具体实施方式Detailed ways

为了使本技术领域的人员更好地理解本申请方案，下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述。In order to enable those skilled in the art to better understand the solutions of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

套接字(Socket)通信是一种进程间通信(Inter-Process Communication，IPC)机制，在操作系统中，通常会为应用程序提供一组应用程序接口(Application ProgrammingInterface，API)，称为套接字接口(Socket API)。应用程序可以通过套接字接口，来使用网络套接字，以进行数据交换。操作系统根据套接字地址，可以决定应该将数据送达特定的行程或线程。Socket通信中，HTTP提供了封装或者显示数据的具体形式，Socket提供了网络通信的能力。Socket (Socket) communication is an inter-process communication (Inter-Process Communication, IPC) mechanism. In the operating system, a set of application programming interfaces (Application Programming Interface, API), called sockets, are usually provided for applications. Word interface (Socket API). Applications can use network sockets for data exchange through the socket interface. Based on the socket address, the operating system can decide that the data should be sent to a specific process or thread. In Socket communication, HTTP provides a specific form of encapsulating or displaying data, and Socket provides the capability of network communication.

Binder通信类似于Socket通信，是一种高效的进程间通信机制，可以实现将进程A的数据发送到进程B。目前，越来越多的终端设备也基于Binder通信机制进行通信，例如，终端设备包含外部存储设备管理模块(Volume Daemon，Vold)以及存储管理服务模块(Storage Manager Service)，在对外部存储设备如存储卡、U盘等进行挂载时，需要外部存储设备管理模块与存储管理服务模块之间的交互，其中，该交互则可以基于Binder通信。其中，终端设备包括但不限于手机、数码相机、便携式电脑和其他终端设备。Binder communication is similar to Socket communication. It is an efficient inter-process communication mechanism that can send data from process A to process B. At present, more and more terminal devices also communicate based on the Binder communication mechanism. For example, the terminal device includes an external storage device management module (Volume Daemon, Vold) and a storage management service module (Storage Manager Service). When the memory card, U disk, etc. are mounted, the interaction between the external storage device management module and the storage management service module is required, and the interaction can be based on Binder communication. Among them, terminal equipment includes but not limited to mobile phones, digital cameras, portable computers and other terminal equipment.

但是，发明人在研究中发现，外部存储设备管理模块与存储管理服务模块基于Binder通信挂载外部存储设备的过程中，如果在Binder调用的过程中被卡住可能会触发系统中的看门狗程序，导致系统无响应，出现如系统卡死或定屏等异常情况。However, the inventor found in the research that during the process of mounting the external storage device based on the Binder communication between the external storage device management module and the storage management service module, if it is stuck in the process of Binder calling, the watchdog in the system may be triggered program, causing the system to become unresponsive, and abnormal situations such as system freezing or freezing of the screen appear.

因此，为了解决上述缺陷，本申请实施例提供了一种挂载处理方法，如图1所示，具体地，该方法包括：S101至S104。Therefore, in order to solve the above defects, an embodiment of the present application provides a mounting processing method, as shown in FIG. 1 , specifically, the method includes: S101 to S104.

S101：存储管理服务模块向外部存储设备管理模块发送第一调用指令。S101: The storage management service module sends a first call instruction to the external storage device management module.

于本实施例中，终端设备包括外部存储设备模块与存储管理服务模块，其中，外部存储设备管理模块是操作系统平台中外部存储系统的管控中心，是管理和控制操作系统平台外部存储设备的后台进程。其功能主要包括：外部存储设备的插拔事件检测、外部存储设备的挂载、卸载、格式化等。存储管理服务模块为操作系统的系统框架层与外部存储设备管理模块进行通信的模块，同时存储管理服务模块也是向应用程序提供存储设备的访问接口及存储设备的挂载消息广播的模块。需要说明的是，外部存储设备管理模块与存储管理服务模块之间基于进程间通信，若二者之间的通信进程卡住，可能导致系统无响应。In this embodiment, the terminal device includes an external storage device module and a storage management service module, wherein the external storage device management module is the management and control center of the external storage system in the operating system platform, and is the background for managing and controlling the external storage device of the operating system platform process. Its functions mainly include: detection of plugging and unplugging events of external storage devices, mounting, unmounting and formatting of external storage devices, etc. The storage management service module is a module for the system framework layer of the operating system to communicate with the external storage device management module, and the storage management service module is also a module that provides the access interface of the storage device and broadcasts the mount message of the storage device to the application program. It should be noted that the external storage device management module and the storage management service module are based on inter-process communication. If the communication process between the two is stuck, the system may not respond.

其中，外部存储设备插入终端设备后，终端设备需对该外部存储设备进行挂载，并在挂载成功后，终端设备上的应用程序可以访问该外部存储设备。Wherein, after the external storage device is inserted into the terminal device, the terminal device needs to mount the external storage device, and after the mounting is successful, the application program on the terminal device can access the external storage device.

在一种实施方式中，在终端设备需对外部存储设备进行挂载时，存储管理服务模块向外部存储设备管理模块发送第一调用指令。In one embodiment, when the terminal device needs to mount the external storage device, the storage management service module sends a first call instruction to the external storage device management module.

S102：外部存储设备管理模块响应于第一调用指令，执行检测操作，且设置外部存储设备的检测状态标识为检测中标识，并返回检测状态标识。S102: The external storage device management module executes a detection operation in response to the first calling instruction, and sets the detection state flag of the external storage device as a detection state flag, and returns the detection state flag.

其中，检测操作为检测外部存储设备的文件系统是否异常。Wherein, the detection operation is to detect whether the file system of the external storage device is abnormal.

其中，检测中标识用于指示存储管理模块外部存储设备管理模块正在执行检测操作且未检测完成，使得在外部存储设备管理模块返回检测状态标识时，存储管理模块基于该检测状态标识为检测中标识，可以获知外部存储设备正在检测中且未检测完成。具体地，终端设备在检测到外部存储设备的插入事件后，外部存储设备管理模块会创建该外部存储设备，并对应存储有该外部存储设备的设备信息，其中设备信息包括检测状态标识。Wherein, the detecting flag is used to indicate that the storage management module and the external storage device management module are performing the detection operation and the detection has not been completed, so that when the external storage device management module returns the detection state flag, the storage management module is marked as the detection state flag based on the detection state , you can know that the external storage device is being detected and the detection has not been completed. Specifically, after the terminal device detects the insertion event of the external storage device, the external storage device management module will create the external storage device and correspondingly store the device information of the external storage device, wherein the device information includes the detection status identifier.

在一些实施方式中，检测时长包括检测文件系统是否异常的耗时以及外部存储设备管理模块在文件系统异常时进行修复的耗时。例如外部存储设备的文件系统损坏过多，可能引发外部存储设备管理模块对外部存储设备的文件系统尝试修复的耗时过长，而过长的修复时长将导致系统卡住。In some implementations, the detection time includes the time spent in detecting whether the file system is abnormal and the time spent in repairing the file system by the external storage device management module when the file system is abnormal. For example, the file system of the external storage device is damaged too much, which may cause the external storage device management module to take too long to repair the file system of the external storage device, and the too long repair time will cause the system to be stuck.

于本实施例中，响应于第一调用指令，外部存储设备管理模块分别执行检测操作，以及设置外部存储设备的检测状态标识为检测中标识，并返回检测状态标识，使得外部存储设备管理模块与存储管理服务模块基于第一调用指令的交互进程无需等待检测操作完成，即可结束，避免了由于检测时长过长导致基于第一调用指令的交互进程卡住，导致系统无响应，具体地，系统无响应包括系统卡死或定屏(屏幕长时间卡住不动，也可称为冻屏或hang机)等系统异常情况，从而可以防止异常外部存储设备插入导致系统不响应，提升系统稳定性。In this embodiment, in response to the first call instruction, the external storage device management module performs detection operations respectively, and sets the detection status flag of the external storage device as the detection status flag, and returns the detection status flag, so that the external storage device management module and The interaction process of the storage management service module based on the first call instruction can end without waiting for the completion of the detection operation, which avoids the interaction process based on the first call instruction being stuck due to too long detection time, causing the system to be unresponsive. Specifically, the system Unresponsiveness includes system abnormalities such as system stuck or fixed screen (the screen is stuck for a long time, also known as frozen screen or hang), so as to prevent the system from not responding due to the insertion of abnormal external storage devices and improve system stability. .

具体地，例如，外部存储设备管理模块响应于第一调用指令，可以将外部存储设备的检测状态标识设置为检测中标识如“checki ng”，在外部存储设备管理模块返回“checking”后，存储管理服务模块可以根据外部存储设备的存储状态标识为“checki ng”，获知外部存储设备正在检测中。Specifically, for example, in response to the first calling instruction, the external storage device management module may set the detection status flag of the external storage device to a detection flag such as "checking", and after the external storage device management module returns "checking", the storage The management service module can learn that the external storage device is being checked according to the storage status of the external storage device as "checking".

S103：外部存储设备管理模块在检测操作已完成时，向存储管理服务模块发送检测完成指令。S103: When the detection operation is completed, the external storage device management module sends a detection completion instruction to the storage management service module.

于本实施例中，外部存储设备管理模块在检测操作已完成时，向存储管理服务模块发送检测完成指令，通知存储管理服务模块对外部存储设备的检测操作已完成，使得存储管理服务模块可以进行下一步操作。In this embodiment, when the detection operation has been completed, the external storage device management module sends a detection completion instruction to the storage management service module, notifying the storage management service module that the detection operation of the external storage device has been completed, so that the storage management service module can perform Next step.

作为一种实施方式，若检测操作的检测时长超过指定时间，结束检测操作，此时检测操作已完成，外部存储设备管理模块向存储管理服务模块发送检测完成指令。需要说明的是，由于在外部存储设备的文件系统是异常时，外部存储设备管理模块尝试对该文件系统进行修复，若修复时间过长且在修复成功之前所耗的检测时长已超过指定时间，则存在当检测操作已完成时，外部存储设备的文件系统仍是异常的情况。即在检测操作已完成时，外部存储设备的文件系统可以是异常的，也可以是非异常的。其中，非异常的情况包括文件系统在检测前即是正常的情况，还可以包括外部存储设备在刚插入时是异常的，但在指定时间内经外部存储设备管理模块修复完成从而恢复正常的情况。As an implementation manner, if the detection duration of the detection operation exceeds a specified time, the detection operation is ended, and the detection operation has been completed at this time, and the external storage device management module sends a detection completion instruction to the storage management service module. It should be noted that when the file system of the external storage device is abnormal, the external storage device management module tries to repair the file system. If the repair time is too long and the detection time before the repair succeeds exceeds the specified time, Then there is a situation that the file system of the external storage device is still abnormal when the detection operation is completed. That is, when the detection operation is completed, the file system of the external storage device may be abnormal or non-abnormal. Among them, the non-abnormal situation includes the situation that the file system is normal before the detection, and it can also include the situation that the external storage device is abnormal when it is just inserted, but it is restored to normal by the external storage device management module within a specified time.

作为另一种实施方式，若检测操作的检测时长超过指定时间，不认为检测操作已完成，即若检测时长过长，在指定时间内未完成检测操作，则认为检测操作未完成，不向存储管理服务模块发送检测完成指令，由此，使得存储管理服务模块无法对外部存储设备进行下一步操作。具体地，由于外部存储设备的文件系统损坏过多，外部存储设备管理模块无法在指定时间内完成对损坏的文件系统的修复。As another implementation, if the detection duration of the detection operation exceeds the specified time, the detection operation is not considered to be completed. The management service module sends a detection completion instruction, thereby preventing the storage management service module from performing the next operation on the external storage device. Specifically, because the file system of the external storage device is damaged too much, the management module of the external storage device cannot finish repairing the damaged file system within a specified time.

需要说明的是，由于外部存储设备管理模块响应于第一调用指令，已完成一次返回，即当次调用线程已结束，而外部存储设备管理模块对外部存储设备执行的检测操作，并不基于与存储管理服务模块之间跨进程通信的线程，而是基于外部存储设备管理模块内部进程内的线程，因此，即便检测时长过长也不会卡住系统进程，也就不会导致系统无响应，从而可以防止由于异常外部存储设备插入终端设备导致的系统卡死或定屏，提升系统稳定性。It should be noted that since the external storage device management module has completed a return in response to the first call instruction, that is, the current calling thread has ended, and the detection operation performed by the external storage device management module on the external storage device is not based on the same The thread of cross-process communication between the storage management service modules is based on the thread in the internal process of the external storage device management module. Therefore, even if the detection time is too long, the system process will not be stuck, and the system will not be unresponsive. In this way, it can prevent the system from freezing or freezing the screen due to the abnormal external storage device being inserted into the terminal device, and improve the system stability.

S104：存储管理服务模块基于检测完成指令通知外部存储设备管理模块对外部存储设备进行挂载。S104: The storage management service module notifies the external storage device management module to mount the external storage device based on the detection completion instruction.

其中，存储管理服务模块基于检测完成指令，可以获知检测操作已完成，此时通知外部存储设备管理模块对外部存储设备进行挂载。Wherein, based on the detection completion instruction, the storage management service module can know that the detection operation has been completed, and at this time, notify the external storage device management module to mount the external storage device.

由此，相较于现有技术中外部存储设备管理模块需在完成检测操作与挂载操作之后才作返回，本实施例通过将检测操作与挂载操作的执行分开，使得外部存储设备管理模块在检测操作完成前，先返回检测状态标识，以结束与存储管理服务模块之间跨进程通信的线程，并在检测操作完成后再进行挂载，因此，可以防止由于对外部存储设备的检测时长过长，导致线程卡住，使得系统无响应，从而可以防止异常外部存储设备插入导致系统卡死或定屏等异常情况，提升系统稳定性。Therefore, compared with the external storage device management module in the prior art, which needs to complete the detection operation and the mounting operation before returning, this embodiment separates the execution of the detection operation from the mounting operation, so that the external storage device management module Before the detection operation is completed, return the detection status flag first to end the thread of cross-process communication with the storage management service module, and mount after the detection operation is completed, so it can prevent the external storage device from being detected for a long time If it is too long, the thread will be stuck, making the system unresponsive, which can prevent abnormal situations such as system freezing or fixed screen caused by abnormal external storage device insertion, and improve system stability.

请参阅图2，示出了本申请实施例提供的一种挂载处理方法，具体地，该方法包括：S201至S207。Please refer to FIG. 2 , which shows a mounting processing method provided by the embodiment of the present application. Specifically, the method includes: S201 to S207.

S201：存储管理服务模块向外部存储设备管理模块发送第一调用指令。S201: The storage management service module sends a first call instruction to the external storage device management module.

作为一种实施方式，第一调用指令包括检测指令，具体地，检测指令可以是用于检测文件系统是否异常、是否有错误的函数Check，也可以是其他在用于检测文件系统是否异常的接口函数，本实施例对此不做限定。基于检测指令，还可以对检测状态标识进行设置或更新等操作。在此实施方式中，存储管理服务模块通过Binder调用将检测指令发送至外部存储设备管理模块。具体地，存储管理服务模块基于Binder通信调用函数Check至外部存储设备管理模块，使得外部存储设备管理模块可以执行函数Check。由此，基于Binder通信可以方便地实现跨进程调用函数。As an implementation, the first call instruction includes a detection instruction, specifically, the detection instruction may be a function Check for detecting whether the file system is abnormal or whether there is an error, or it may be other interfaces used for detecting whether the file system is abnormal. function, which is not limited in this embodiment. Based on the detection instruction, operations such as setting or updating the detection status flag may also be performed. In this implementation manner, the storage management service module sends the detection instruction to the external storage device management module through a Binder call. Specifically, the storage management service module calls the function Check to the external storage device management module based on the Binder communication, so that the external storage device management module can execute the function Check. Therefore, based on Binder communication, it is convenient to implement cross-process calling functions.

作为另一种实施方式，检测指令可以是预先加载的，即第一调用指令不包含检测指令，此时，存储管理服务模块向外部存储设备管理模块发送第一调用指令，可以使得外部存储设备管理模块响应于第一调用指令，可以执行预先加载的检测指令，减少进程间的通信数据量，降低函数加载时间，提高通信效率，提高检测效率，进而有利于提高对外部存储设备的挂载效率。As another implementation, the detection instruction may be preloaded, that is, the first call instruction does not contain the detection instruction. At this time, the storage management service module sends the first call instruction to the external storage device management module, which can make the external storage device manage In response to the first call instruction, the module can execute preloaded detection instructions, reduce the amount of communication data between processes, reduce function loading time, improve communication efficiency, improve detection efficiency, and then help improve the mounting efficiency of external storage devices.

S202：外部存储设备管理模块响应于第一调用指令，执行检测操作，且设置外部存储设备的检测状态标识为检测中标识，并返回检测状态标识。S202: The external storage device management module executes a detection operation in response to the first call instruction, and sets the detection state flag of the external storage device as a detection state flag, and returns the detection state flag.

其中，检测状态标识可以是对应外部存储设备的用于反映当前检测状态的标志位，通过该标识位，可以获知当前检测的状态，例如，若该标志位为检测中标识如“Checking”，可以表示外部存储设备管理模块正在对外部存储设备执行检测操作且未检测完成，存储管理服务模块通过接收外部存储设备管理模块返回的检测状态标识，可以获知当前检测的状态为正在执行检测操作且未检测完成。Wherein, the detection state flag can be a flag bit corresponding to the external storage device used to reflect the current detection state, through which the state of the current detection can be known, for example, if the flag bit is a flag in detection such as "Checking", you can Indicates that the external storage device management module is performing a detection operation on the external storage device and the detection has not been completed. The storage management service module can know that the current detection status is performing the detection operation and not detected by receiving the detection status identifier returned by the external storage device management module.

于本实施例中，外部存储设备管理模块响应于第一调用指令，可以基于两个不同的线程分别执行检测操作和设置外部存储设备的检测状态标识并返回检测状态标识。具体地，外部存储设备管理模块响应于第一调用指令，基于第一线程设置外部存储设备的检测状态标识为检测中标识，并返回检测状态标识，使得第一线程在接收到第一调用指令后立刻返回执行结束了，并且外部存储设备管理模块响应于第一调用指令，基于第二线程执行检测操作。In this embodiment, in response to the first calling instruction, the external storage device management module may respectively perform the detection operation and set the detection state flag of the external storage device based on two different threads, and return the detection state flag. Specifically, in response to the first call instruction, the external storage device management module sets the detection state flag of the external storage device as a detection flag based on the first thread, and returns the detection state flag, so that the first thread receives the first call instruction Immediately returning execution ends, and the external storage device management module performs a detection operation based on the second thread in response to the first calling instruction.

其中，第一线程是基于Binder调用的跨进程的线程，即主线程，而第二线程是外部存储设备管理模块进程内的线程，由此，本实施例通过第一线程在接收到第一调用指令之后，立刻返回执行结束了，使得本次Binder调用的线程可以及时结束，并且开启第二线程执行实际的检测操作，使得实际的检测时长，并且其中还包含的修复时长不影响主线程，即基于第二线程执行可能导致Binder调用卡住的检测操作，使得基于Binder调用的第一线程可以得到及时甚至快速的响应，很好地避免了由于检测时长过长导致的系统无响应，防止了异常外部存储设备插入导致的系统卡死或定屏等异常情况发生，大大提升了系统的稳定性。Wherein, the first thread is a cross-process thread based on the Binder call, that is, the main thread, and the second thread is a thread in the process of the external storage device management module. Therefore, in this embodiment, the first thread receives the first call through the first thread. After the instruction, the execution is returned immediately, so that the thread called by Binder can end in time, and the second thread is started to perform the actual detection operation, so that the actual detection duration and the repair duration included in it will not affect the main thread, that is Based on the detection operation that may cause the Binder call to be stuck based on the second thread, the first thread based on the Binder call can get a timely or even fast response, which well avoids the system being unresponsive due to the long detection time and prevents exceptions. Abnormal situations such as system freezing or fixed screen caused by the insertion of external storage devices have greatly improved the stability of the system.

作为一种实施方式，第一进程先于第二进程进行，具体地，外部存储设备管理模块响应于第一调用指令，先基于第一线程设置检测状态标识为检测中标识，并返回检测状态标识，此时再开启第二线程，基于第二线程执行检测操作。As an implementation, the first process is performed before the second process. Specifically, the external storage device management module responds to the first call instruction, first sets the detection status flag as the detection flag based on the first thread, and returns the detection status flag , and then start the second thread at this time, and perform the detection operation based on the second thread.

作为另一种实施方式，第一进程与第二进程同时进行，具体地，外部存储设备管理模块响应于第一调用指令，同时设置检测状态标识以及开启第二线程并基于第二线程执行检测操作，在检测操作完成前即可立刻返回检测状态标识，并且由于第二线程与第一线程同时进行，使得外部存储设备管理模块响应于第一调用指令，在可以及时结束Binder调用的基础上，还可以更快执行检测操作，提高检测效率，同时更高的检测效率还有利于提高对外部存储设备的挂载效率。As another implementation, the first process and the second process are performed at the same time, specifically, the external storage device management module responds to the first call instruction, simultaneously sets the detection status flag and starts the second thread, and performs the detection operation based on the second thread , the detection status flag can be returned immediately before the detection operation is completed, and since the second thread and the first thread are carried out simultaneously, the external storage device management module can respond to the first call instruction and end the Binder call in time. The detection operation can be performed faster, and the detection efficiency is improved, and the higher detection efficiency is also conducive to improving the mounting efficiency of the external storage device.

其中，检测操作为检测外部存储设备的文件系统是否异常，并针对异常的文件系统进行修复。需要说明的是，检测操作包括在检测到异常时，对异常的文件系统进行修复的操作，故本实施例中，检测时长包括修复时长。具体地，若文件系统存在损坏，则异常，无损坏则正常，并在异常时外部存储设备管理模块将尝试修复异常的文件系统。进一步地，若修复完成，此时文件系统无损坏，可以认为是无异常即正常的。Wherein, the detection operation is to detect whether the file system of the external storage device is abnormal, and repair the abnormal file system. It should be noted that the detection operation includes the operation of repairing the abnormal file system when an abnormality is detected, so in this embodiment, the detection duration includes the repair duration. Specifically, if the file system is damaged, it is abnormal, and if there is no damage, it is normal, and the external storage device management module will try to repair the abnormal file system when abnormal. Further, if the restoration is completed, the file system is not damaged at this time, and it can be considered normal without exception.

在一些实施方式中，若文件系统正常或者文件系统异常且修复完成，则外部存储设备管理模块判定检测操作已完成，并且若文件系统异常且未修复完成，则文件系统仍处于异常状态，外部存储设备管理模块判定检测操作未完成。其中：In some embodiments, if the file system is normal or the file system is abnormal and the repair is completed, the external storage device management module determines that the detection operation has been completed, and if the file system is abnormal and the repair is not completed, the file system is still in an abnormal state, and the external storage device The device management module determines that the detection operation is not completed. in:

作为一种方式，若文件系统正常或者文件系统异常且修复完成，则外部存储设备管理模块判定检测操作已完成；若文件系统异常且无法修复，则外部存储设备管理模块判定检测操作未完成。由此，对于检测操作不限时长，并当文件系统异常时，判定检测操作未完成。从而在修复完成时，可以及时判定检测操作已完成，以便进行下一步操作。As a method, if the file system is normal or the file system is abnormal and the repair is completed, the external storage device management module determines that the detection operation has been completed; if the file system is abnormal and cannot be repaired, the external storage device management module determines that the detection operation is not completed. Thus, there is no time limit for the detection operation, and when the file system is abnormal, it is determined that the detection operation is not completed. Therefore, when the restoration is completed, it can be determined in time that the detection operation has been completed, so as to proceed to the next operation.

作为另一种方式，外部存储设备管理模块的检测操作对应设置有预设时长，并在文件系统异常且在预设时长内未修复完成时，即检测时长超过预设时长时，判定检测操作未完成。具体地，若检测到文件系统正常，此时无需修复，外部存储设备管理模块判定检测操作已完成；若检测到文件系统异常但在预设时长内修复完成，则外部存储设备管理模块判定检测操作已完成；若检测时长超过预设时长但仍未修复完成，此时外部存储设备管理模块检测到文件系统异常，但在预设时长内损坏的文件系统未被修复完成，则判定检测操作未完成。由此，可以控制检测操作的执行时间，可以及时作出响应以便进行下一步操作，从而保证检测效率的同时，避免检测超时无响应，提高系统可用性。As another way, the detection operation of the external storage device management module is correspondingly set with a preset duration, and when the file system is abnormal and has not been repaired within the preset duration, that is, when the detection duration exceeds the preset duration, it is determined that the detection operation is not completed. Finish. Specifically, if it is detected that the file system is normal and there is no need to repair it at this time, the external storage device management module determines that the detection operation has been completed; Completed; if the detection time exceeds the preset time but the repair is still not completed, the external storage device management module detects an abnormal file system at this time, but the damaged file system has not been repaired within the preset time, then it is determined that the detection operation has not been completed . In this way, the execution time of the detection operation can be controlled, and a response can be made in time for the next operation, so as to ensure the detection efficiency, avoid detection timeout and no response, and improve system availability.

在另一些实施方式中，外部存储设备管理模块的检测操作对应设置有预设时长，并在文件系统异常且在预设时长内未修复完成时，即检测时长超过预设时长时，仍判定检测操作已完成。具体地，若文件系统正常或者文件系统异常且修复完成，则外部存储设备管理模块判定检测操作已完成，并且若文件系统异常且在预设时长内未修复完成，则文件系统仍处于异常状态，此时外部存储设备管理模块仍判定检测操作完成。也就是，检测操作最多可以执行预设时长，并且达到预设时长时，判定检测操作已完成，此时包括文件系统可以是正常的，也可以是异常的。由此，可以控制检测操作的执行时间，并在文件系统未修复完成时仍判定检测操作已完成，可以及时作出响应以便进行下一步操作，从而保证检测效率的同时，避免检测超时无响应，提高系统可用性。In some other implementations, the detection operation of the external storage device management module is correspondingly set with a preset duration, and when the file system is abnormal and has not been repaired within the preset duration, that is, when the detection duration exceeds the preset duration, it is still determined that the detection Operation complete. Specifically, if the file system is normal or the file system is abnormal and the repair is completed, the external storage device management module determines that the detection operation has been completed, and if the file system is abnormal and the repair is not completed within the preset time length, the file system is still in the abnormal state, At this time, the external storage device management module still determines that the detection operation is completed. That is, the detection operation can be performed for a preset duration at most, and when the preset duration is reached, it is determined that the detection operation has been completed. At this time, the file system may be normal or abnormal. In this way, the execution time of the detection operation can be controlled, and the detection operation can still be judged to be completed when the file system has not been repaired, and a response can be made in time for the next operation, thereby ensuring detection efficiency while avoiding detection timeout and no response, improving System availability.

进一步地，在检测时长超过预设时长时，外部存储设备管理模块可以终止检测操作，也可以不终止，具体的实施方式如下：Further, when the detection duration exceeds the preset duration, the external storage device management module may or may not terminate the detection operation. The specific implementation method is as follows:

在一种实施方式中，在检测时长超过预设时长时，外部存储设备管理模块可以终止检测操作，节省资源，提高系统可用性。In an implementation manner, when the detection duration exceeds a preset duration, the external storage device management module may terminate the detection operation to save resources and improve system availability.

在另一种实施方式中，在检测时长超过预设时长时，外部存储设备管理模块也可以不终止检测操作，使得检测操作继续，具体地，在文件系统损坏过多时，外部存储设备管理模块要完成对所有异常的文件系统的修复，所需时长较长，并且所需时长可能超过预设时长，此时通过在检测时长超过预设时长时，仍不中断检测操作，使得外部存储设备管理模块可以继续修复，由此，存在在挂载操作执行前，完成修复的可能，此时检测操作未完成的外部存储设备仍具有可被成功挂载的可能。具体的实施方式，可以参见后述实施例，本实施例不再赘述。In another embodiment, when the detection duration exceeds the preset duration, the external storage device management module may not terminate the detection operation, so that the detection operation continues. Specifically, when the file system is damaged too much, the external storage device management module needs to It takes a long time to complete the repair of all abnormal file systems, and the required time may exceed the preset time. At this time, when the detection time exceeds the preset time, the detection operation is still not interrupted, so that the external storage device management module The repair can be continued, thus, there is a possibility that the repair can be completed before the mount operation is performed, and at this time, the external storage device whose detection operation has not been completed may still be successfully mounted. For specific implementation manners, reference may be made to the following embodiments, and details will not be repeated in this embodiment.

进一步地，于本实施例中，在检测时长超过预设时长时，可以执行S204；在检测时长未超过预设时长时，可以执行S203。Further, in this embodiment, when the detection duration exceeds the preset duration, S204 may be executed; when the detection duration does not exceed the preset duration, S203 may be executed.

S203：当检测时长超过预设时长时，外部存储设备管理模块设置检测状态标识为检测异常标识。S203: When the detection duration exceeds the preset duration, the external storage device management module sets the detection status flag as a detection abnormality flag.

其中，检测状态标识还包括检测异常标识，该检测异常标识可以用于指示存储管理服务模块当前检测异常，即检测时长超过预设时长仍未修复完成，此时外部存储设备的文件系统仍异常。Wherein, the detection status flag also includes a detection abnormality flag, which can be used to indicate that the storage management service module is currently detecting an abnormality, that is, the detection time exceeds the preset time and has not been repaired, and the file system of the external storage device is still abnormal at this time.

于本实施例中，当检测时长超过预设时长时，外部存储设备管理模块设置检测状态标识为检测异常标识。具体地，在一种实施方式中，检测异常标识可以是数字、字母、单词等字符串，如“0”、“uncheckable”等用于表征经检测操作后文件系统仍异常，可以是系统预设的，也可以是自定义的，从而通过该检测异常标识，可以获知文件系统异常，另外，本实施例对检测异常标识的命名形式不做其他限定。In this embodiment, when the detection duration exceeds the preset duration, the external storage device management module sets the detection status flag as a detection abnormality flag. Specifically, in one implementation, the abnormality detection flag can be a string of numbers, letters, words, etc., such as "0", "uncheckable", etc., used to indicate that the file system is still abnormal after the detection operation, and can be a system preset It can also be self-defined, so that the abnormality of the file system can be known through the abnormality detection flag. In addition, this embodiment does not make other restrictions on the naming form of the abnormality detection flag.

由于文件系统异常时，外部存储设备难以挂载成功，故当文件系统异常且在预设时长内未修复完成时，通过设置检测异常标识，可以在检测到检测异常标识时，不对该外部存储设备进行挂载，从而减少不必要的资源消耗，提高响应效率。具体的实施方式，可见后述实施例，在此不作赘述。When the file system is abnormal, it is difficult for the external storage device to mount successfully. Therefore, when the file system is abnormal and has not been repaired within the preset time, by setting the abnormal detection flag, the external storage device will not be detected when the abnormal detection flag is detected. Mount to reduce unnecessary resource consumption and improve response efficiency. Specific implementation manners can be seen in the following embodiments, and details are not repeated here.

S204：外部存储设备管理模块在检测操作已完成时，向存储管理服务模块发送检测完成指令。S204: When the detection operation is completed, the external storage device management module sends a detection completion instruction to the storage management service module.

于本实施例中，在检测操作已完成时，外部存储设备的文件系统可以是正常的，也可以是异常的，其中正常的包括本身即正常的情况，以及异常但修复完成的情况。In this embodiment, when the detection operation is completed, the file system of the external storage device may be normal or abnormal, wherein the normal includes the normal itself and the abnormal but repaired.

作为一种实施方式，若文件系统异常且在预设时长内未修复完成，即检测时长超过预设时长时，仍判定检测操作已完成，此时通过外部存储设备管理模块向存储管理服务模块发送检测完成指令，使得存储管理服务模块通过接收到该检测完成指令，可以获知当前外部存储设备已完成检测操作，可以进行挂载。此时，外部存储设备的文件系统可以异常的，也可以是非异常的。As an implementation, if the file system is abnormal and has not been repaired within the preset time period, that is, when the detection time exceeds the preset time period, it is still determined that the detection operation has been completed. At this time, the external storage device management module sends the file system to the storage management service module. The detection completion instruction enables the storage management service module to know that the current external storage device has completed the detection operation and can be mounted after receiving the detection completion instruction. At this time, the file system of the external storage device may be abnormal or non-abnormal.

作为另一种实施方式，若文件系统异常且在预设时长内未修复完成，即检测时长超过预设时长时，判定检测操作未完成，此时通过外部存储设备管理模块向存储管理服务模块发送检测完成指令，使得存储管理服务模块通过接收到该检测完成指令，可以获知当前外部存储设备是正常的，可以进行挂载。此时，外部存储设备的文件系统是非异常的，即在外部存储设备的文件系统仍异常时，不发送检测完成指令。As another implementation, if the file system is abnormal and has not been repaired within the preset time, that is, when the detection time exceeds the preset time, it is determined that the detection operation has not been completed. At this time, the external storage device management module sends the The detection completion instruction enables the storage management service module to know that the current external storage device is normal and can be mounted after receiving the detection completion instruction. At this time, the file system of the external storage device is not abnormal, that is, when the file system of the external storage device is still abnormal, no detection completion instruction is sent.

S205：存储管理服务模块基于检测完成指令通知外部存储设备管理模块对外部存储设备进行挂载。S205: The storage management service module notifies the external storage device management module to mount the external storage device based on the detection completion instruction.

于本实施例中，存储管理服务模块基于检测完成指令，可以判定当前外部存储设备已完成检测操作，可以进行挂载，此时通知外部存储设备管理模块对该外部存储设备进行挂载。由此，将检测操作和挂载操作分开在不同的线程执行，并在通过检测操作判定外部存储设备的文件系统是正常的情况时，才进行挂载，可以提高挂载成功率以及效率。In this embodiment, based on the detection completion instruction, the storage management service module can determine that the current external storage device has completed the detection operation and can be mounted, and at this time notifies the external storage device management module to mount the external storage device. Therefore, the detection operation and the mounting operation are performed separately in different threads, and the file system of the external storage device is mounted only when the detection operation determines that the file system of the external storage device is normal, which can improve the success rate and efficiency of the mounting.

S206：外部存储设备管理模块对外部存储设备进行挂载时，确定是否能够查找到检测异常标识。S206: When the external storage device management module mounts the external storage device, it is determined whether the detected abnormality identifier can be found.

在一些实施方式中，若文件系统异常且在预设时长内未修复完成，即检测时长超过预设时长时，仍判定检测操作已完成，外部存储设备管理设备管理模块对外部存储设备进行挂载时，确定是否能够查找到检测异常标识，具体地，例如，基于表征检测状态的标志位，判断该标志位上的检测状态标识是否位检测异常标识；再如，可以直接查找对应该外部存储设备是否存储检测异常标识。In some embodiments, if the file system is abnormal and has not been repaired within the preset time period, that is, when the detection time exceeds the preset time period, it is still determined that the detection operation has been completed, and the external storage device management module mounts the external storage device When determining whether the abnormal detection flag can be found, specifically, for example, based on the flag bit representing the detection state, it is judged whether the detection state flag on the flag bit is an abnormal detection flag; Whether to store detected exception flags.

在另一些实施方式中，若文件系统异常且在预设时长内未修复完成，即检测时长超过预设时长时，判定检测操作未完成，则在S205之后不执行S206至S207，此时，外部存储设备的文件系统是非异常的，也就无需查找检测异常标识。In other embodiments, if the file system is abnormal and has not been repaired within the preset time period, that is, when the detection time exceeds the preset time period, it is determined that the detection operation has not been completed, and then S206 to S207 are not executed after S205. At this time, the external The file system of the storage device is non-abnormal, so there is no need to find and detect an abnormality identifier.

进一步地，若能够查找到检测异常标识，可以执行S207；若不能够，可以继续执行挂载操作。Further, if the detected abnormality identification can be found, S207 can be executed; if not, the mounting operation can be continued.

S207：若能够，则停止对外部存储设备进行挂载。S207: If possible, stop mounting the external storage device.

若能够查找到检测异常标识，此时外部存储设备管理模块判定外部存储设备的文件系统为异常，通过停止对外部存储设备进行挂载，可以降低运行资源的消耗，提高系统运行效率，并有利于提高挂载效率。If the abnormality detection flag can be found, the external storage device management module determines that the file system of the external storage device is abnormal. By stopping the external storage device from being mounted, the consumption of operating resources can be reduced, the operating efficiency of the system can be improved, and it is beneficial to Improve loading efficiency.

需要说明的是，上述步骤中未详细描述的部分，可参考前述实施例，在此不再赘述。It should be noted that, for parts not described in detail in the above steps, reference may be made to the foregoing embodiments, and details are not repeated here.

本实施例提供的挂载处理方法，通过将检测操作和挂载操作分开在不同的线程执行，通过外部存储设备管理模块在接收到第一调用指令之后，立刻返回使得本次Binder调用的线程可以及时结束，并开启第二线程执行实际的检测操作，使得实际的检测时长，并且其中还包含的修复时长不影响主线程，即基于第二线程执行可能导致Binder调用卡住的检测操作，避免了由于检测时长过长导致的系统无响应，防止了异常外部存储设备插入导致的系统卡死或定屏等异常情况发生，大大提升了系统的稳定性。并且，通过确定是否能够找到检测异常标识，使得外部存储设备管理设备在外部存储设备的文件系统是非异常时，才继续进行挂载，还可以提高挂载成功率以及效率，另外，由于外部存储设备管理模块在文件系统异常时不进行挂载，还可以减少不必要的资源消耗，提高系统运行效率。The mount processing method provided by this embodiment, by separating the detection operation and the mount operation into different threads, the external storage device management module returns immediately after receiving the first call instruction so that the thread called by the Binder can End in time, and start the second thread to perform the actual detection operation, so that the actual detection time, and the repair time included in it will not affect the main thread, that is, the detection operation that may cause the Binder call to be stuck based on the second thread execution, avoiding The system does not respond due to too long detection time, which prevents abnormal situations such as system freezing or fixed screen caused by the insertion of abnormal external storage devices, and greatly improves the stability of the system. Moreover, by determining whether the detection abnormality mark can be found, the external storage device management device continues to mount when the file system of the external storage device is normal, which can also improve the success rate and efficiency of the mount. In addition, because the external storage device The management module does not mount when the file system is abnormal, which can also reduce unnecessary resource consumption and improve system operating efficiency.

另外，在检测时长超过预设时长时，也可以结束本次方法，不进行下一步操作。具体地，请参阅图3，该方法包括：S301至S303。In addition, when the detection duration exceeds the preset duration, the current method may also be terminated without performing the next step. Specifically, referring to FIG. 3 , the method includes: S301 to S303.

S301：存储管理服务模块向外部存储设备管理模块发送第一调用指令。S301: The storage management service module sends a first call instruction to the external storage device management module.

S302：外部存储设备管理模块响应于第一调用指令，执行检测操作，且设置外部存储设备的检测状态标识为检测中标识，并返回检测状态标识。S302: The external storage device management module executes a detection operation in response to the first call instruction, and sets the detection state flag of the external storage device as a detection state flag, and returns the detection state flag.

S303：当检测时长超过预设时长时，外部存储设备管理模块设置检测状态标识为检测异常标识。S303: When the detection duration exceeds the preset duration, the external storage device management module sets the detection status flag as a detection abnormality flag.

于本实施例中，当检测时长超过预设时长时，结束本次方法，使得在文件系统异常且在预设时长内未修复完成时，不通知存储管理服务模块而结束本次方法，可以大大减少运行资源的消耗，提高系统运行效率。In this embodiment, when the detection duration exceeds the preset duration, the method is ended, so that when the file system is abnormal and has not been repaired within the preset duration, the storage management service module is not notified and the method is terminated, which can be greatly improved. Reduce the consumption of operating resources and improve the operating efficiency of the system.

进一步地，作为一种方式，当检测时长超过预设时长时，可以先执行S303，再结束本次方法。此时外部存储设备管理模块设置检测状态标识为检测异常标识，使得在存储管理服务模块获取到外部存储设备的检测状态标识时，可以获知外部存储设备的文件系统处于异常状态，从而使得用户可以及时尝试重新挂载。Further, as a way, when the detection duration exceeds the preset duration, S303 may be executed first, and then this method ends. At this time, the external storage device management module sets the detection status identification as the abnormal detection identification, so that when the storage management service module obtains the detection status identification of the external storage device, it can know that the file system of the external storage device is in an abnormal state, so that the user can timely Try remounting.

作为另一种方式，当检测时长超过预设时长时，可以不执行S303，而结束本次方法。此时存储管理服务模块认为外部存储设备一直处于检测中，仍在执行检测操作，具体地，外部存储设备对应地检测状态一直为“Checking”。As another manner, when the detection duration exceeds the preset duration, S303 may not be executed, and this method ends. At this time, the storage management service module considers that the external storage device has been being checked and is still performing the checking operation. Specifically, the corresponding detection status of the external storage device is always "Checking".

S304：外部存储设备管理模块在检测操作已完成时，向存储管理服务模块发送检测完成指令。S304: When the detection operation is completed, the external storage device management module sends a detection completion instruction to the storage management service module.

S305：存储管理服务模块基于检测完成指令通知外部存储设备管理模块对外部存储设备进行挂载。S305: The storage management service module notifies the external storage device management module to mount the external storage device based on the detection completion instruction.

需要说明的是，上述步骤中为详细描述的部分，可参考前述实施例，在此不再赘述。It should be noted that, for the part described in detail in the above steps, reference may be made to the foregoing embodiments, and details are not repeated here.

本实施例提供的挂载处理方法，在前述实施例的基础上，通过在检测时长超过预设时长时，结束本次方法，可以大大减少运行资源的消耗，提高运行效率，并且可以使得用户通过重新插入外部存储设备或其他措施，重新尝试挂载，提高用户挂载体验。The mounting processing method provided in this embodiment, on the basis of the foregoing embodiments, terminates the method when the detection duration exceeds the preset duration, which can greatly reduce the consumption of operating resources, improve operating efficiency, and allow users to pass Reinsert the external storage device or take other measures to retry the mount to improve the user mount experience.

请参阅图4，示出了本申请实施例提供的一种挂载处理方法，具体地，该方法包括：S401至S404。Please refer to FIG. 4 , which shows a mounting processing method provided by the embodiment of the present application. Specifically, the method includes: S401 to S404.

S401：存储管理服务模块向外部存储设备管理模块发送第一调用指令。S401: The storage management service module sends a first call instruction to the external storage device management module.

S402：外部存储设备管理模块响应于第一调用指令，执行检测操作，且设置外部存储设备的检测状态标识为检测中标识，并返回检测状态标识。S402: The external storage device management module executes a detection operation in response to the first call instruction, and sets the detection state flag of the external storage device as a detection state flag, and returns the detection state flag.

S403：外部存储设备管理模块在检测操作已完成时，向存储管理服务模块发送检测完成指令。S403: When the detection operation is completed, the external storage device management module sends a detection completion instruction to the storage management service module.

上述S401至S403的具体实施方式可参考前述实施例，在此不再赘述。For specific implementation manners of the foregoing S401 to S403, reference may be made to the foregoing embodiments, and details are not repeated here.

S404：存储管理服务模块响应于检测完成指令，向外部存储设备管理模块发送第二调用指令。S404: The storage management service module sends a second call instruction to the external storage device management module in response to the detection completion instruction.

其中，第二调用指令用于通知外部存储设备管理模块对外部存储设备进行挂载。Wherein, the second calling instruction is used to notify the external storage device management module to mount the external storage device.

作为一种实施方式，存储管理服务模块响应于检测完成指令，通过Binder调用将挂载指令发送至外部存储设备管理模块，其中，第二调用指令包括挂载指令，例如，挂载指令可以是用于挂载外部存储设备的函数Mount，也可以是其他用于挂载外部存储设备的接口函数，本实施例对此不作限定。具体地，存储管理服务模块基于Binder通信调用函数Mount至外部存储设备管理模块，使得外部存储设备管理模块可以执行函数Mount，执行挂载操作。As an implementation, the storage management service module sends the mount instruction to the external storage device management module through a Binder call in response to the detection completion instruction, wherein the second call instruction includes the mount instruction, for example, the mount instruction can be The function Mount for mounting an external storage device may also be other interface functions for mounting an external storage device, which is not limited in this embodiment. Specifically, the storage management service module calls the function Mount to the external storage device management module based on the Binder communication, so that the external storage device management module can execute the function Mount to perform a mount operation.

作为另一种实施方式，挂载指令可以是预先加载的，即第二调用指令不包括挂载指令，此时，存储管理服务模块向外部存储设备管理模块发送第二调用指令，可以使得外部存储设备管理模块响应于第二调用指令，可以执行预先加载的挂载指令，减少进程间的通信数据量，降低函数加载时间，提高通信效率的同时提高挂载效率。As another implementation, the mount instruction may be preloaded, that is, the second call instruction does not include the mount instruction. At this time, the storage management service module sends the second call instruction to the external storage device management module, which can make the external storage In response to the second calling instruction, the device management module can execute the preloaded mounting instruction, reduce the amount of communication data between processes, reduce the function loading time, improve communication efficiency and improve mounting efficiency.

请参阅图5，示出了本申请实施例提供的一种挂载处理方法，具体地，该方法包括：S501至S507。Please refer to FIG. 5 , which shows a mounting processing method provided by the embodiment of the present application. Specifically, the method includes: S501 to S507.

S501：存储管理服务模块向外部存储设备管理模块发送第一调用指令。S501: The storage management service module sends a first calling instruction to the external storage device management module.

S503：外部存储设备管理模块在检测操作已完成时，向存储管理服务模块发送检测完成指令。S503: When the detection operation is completed, the external storage device management module sends a detection completion instruction to the storage management service module.

S504：存储管理服务模块响应于检测完成指令，向外部存储设备管理模块发送第二调用指令。S504: The storage management service module sends a second call instruction to the external storage device management module in response to the detection completion instruction.

S505：外部存储设备管理模块响应于第二调用指令，根据检测状态标识，判断外部存储设备的文件系统是否异常。S505: The external storage device management module determines whether the file system of the external storage device is abnormal according to the detection status flag in response to the second calling instruction.

于本实施例中，外部存储设备管理模块响应于第二调用指令，根据外部存储设备对应的检测状态标识，判断外部存储设备的文件系统是否异常。具体地，若当前的检测状态标识为检测异常标识，外部存储设备的文件系统异常，否则非异常，即文件系统正常。In this embodiment, the external storage device management module determines whether the file system of the external storage device is abnormal according to the detection status identifier corresponding to the external storage device in response to the second call instruction. Specifically, if the current detection status flag is a detection abnormality flag, the file system of the external storage device is abnormal; otherwise, it is not abnormal, that is, the file system is normal.

本实施例中，S505之后，若非异常，可以执行S506；若异常，可以执行S508。In this embodiment, after S505, if there is no abnormality, S506 can be executed; if there is an abnormality, S508 can be executed.

S506：外部存储设备管理模块获取挂载结果。S506: The external storage device management module acquires a mounting result.

若非异常，此时外部存储设备管理模块检测到外部存储设备的文件系统非异常，外部存储设备管理模块对外部存储设备执行挂载操作，获取挂载结果。具体地，外部存储设备管理模块基于挂载指令，如用于挂载的函数Mount，通过执行该函数Mount，对外部存储设备执行挂载操作，获取挂载结果。其中，挂载结果包括挂载成功和挂载失败。If it is not abnormal, the external storage device management module detects that the file system of the external storage device is not abnormal, and the external storage device management module performs a mount operation on the external storage device to obtain a mount result. Specifically, the external storage device management module executes a mount operation on the external storage device based on a mount command, such as a function Mount for mounting, and obtains a mount result. Wherein, the mount result includes mount success and mount failure.

S507：外部存储设备管理模块根据挂载结果，设置挂载状态标识。S507: The external storage device management module sets a mounting state identifier according to the mounting result.

具体地，挂载状态标识可以是一个用于表征挂载状态的标志位，例如，若挂载状态标识为“unmountable”，表征外部存储设备无法挂载，若挂载状态标识为“mounted”，表征外部存储设备已挂载。需要说明的是，只要挂载状态标识可以用于表征挂载状态，本实施例对挂载状态标识的命名形式不作其他限定。Specifically, the mount status identifier may be a flag bit used to represent the mount status. For example, if the mount status identifier is "unmountable", it indicates that the external storage device cannot be mounted; if the mount status identifier is "mounted", Indicates that the external storage device is mounted. It should be noted that, as long as the mounting state identifier can be used to represent the mounting state, this embodiment does not impose other limitations on the naming form of the mounting state identifier.

作为一种实施方式，若挂载成功，设置挂载状态标识为已挂载标识，如“mounted”；若挂载失败，设置挂载状态标识为无法挂载标识，如“unmountable”，或设置为未挂载标识，如“unmounted”。从而使得存储管理服务模块通过获取挂载状态标识可以获知对应的挂载结果。As an implementation, if the mount is successful, set the mount status flag to the mounted flag, such as "mounted"; if the mount fails, set the mount status flag to the unmountable flag, such as "unmountable", or set Unmounted flag, such as "unmounted". Therefore, the storage management service module can obtain the corresponding mounting result by obtaining the mounting state identifier.

S508：设置外部存储设备的挂载状态标识为无法挂载标识。S508: Set the mount status flag of the external storage device as an flag that cannot be mounted.

若异常，此时外部存储设备管理模块检测到外部存储设备的文件系统异常，此时设置外部存储设备的挂载状态标识为无法挂载标识，使得外部存储设备管理模块无法对外部存储设备进行挂载。由于文件系统异常时，对外部存储设备挂载成功的可能性低，因此通过判断外部存储设备的文件系统是否异常，可以判断挂载成功的可能性，从而在实际执行挂载操作前作出预判，并在文件系统异常时，停止挂载，可以节省资源，提高挂载效率。If it is abnormal, the external storage device management module detects that the file system of the external storage device is abnormal. At this time, the mount status flag of the external storage device is set as an unmountable flag, so that the external storage device management module cannot mount the external storage device. load. When the file system is abnormal, the possibility of successfully mounting the external storage device is low. Therefore, by judging whether the file system of the external storage device is abnormal, the possibility of successful mounting can be judged, so as to make a prediction before actually performing the mounting operation. , and when the file system is abnormal, stop mounting, which can save resources and improve mounting efficiency.

作为一种实施方式，S508之后可以结束本次方法，即设置挂载状态标识后再结束本次方法，使得存储管理服务模块可以获取该挂载状态标识，从而获知当前插入的外部存储设备无法挂载，使得用户可以采取措施重新挂载该外部存储设备，如重新插入等，提升用户挂载外部存储设备的用户体验。As an implementation, after S508, this method can be ended, that is, after setting the mounting status identifier, this method can be ended, so that the storage management service module can obtain the mounting status identifier, so as to know that the currently inserted external storage device cannot be mounted. Mount, so that the user can take measures to remount the external storage device, such as reinserting, etc., to improve the user experience of mounting the external storage device.

作为另一种实施方式，S508之前可以结束本次方法，即若外部存储设备管理模块判断外部存储设备的文件系统异常，不执行S508，而结束本次方法。进一步节省挂载所需的运行资源，由于在文件系统异常时，难以对外部存储设备挂载成功，因此，本实施方式通过在文件系统异常时，不执行实际的挂载操作，例如不执行函数Mount等操作，而结束本次方法，可以减少不必要的运行资源。As another implementation manner, this method may end before S508, that is, if the external storage device management module determines that the file system of the external storage device is abnormal, S508 is not executed, and this method ends. To further save the running resources required for mounting, since it is difficult to successfully mount the external storage device when the file system is abnormal, this embodiment does not perform the actual mounting operation when the file system is abnormal, for example, does not execute the function Mount and other operations, and ending this method can reduce unnecessary running resources.

作为又一种实施方式，S508之后可以将无法挂载标识发送至存储管理服务模块，使得存储管理服务模块可以获知外部存储设备的当前挂载状态。具体的实施方式，可以参考后述实施例，在此不再赘述。As yet another implementation manner, after S508, the unmountable identifier may be sent to the storage management service module, so that the storage management service module may know the current mount status of the external storage device. For specific implementation manners, reference may be made to the following embodiments, and details are not repeated here.

需要说明的是，上述步骤中未详细描述的部分，可参考前述实施例，在此不再赘述。It should be noted that, for parts not described in detail in the above steps, reference may be made to the foregoing embodiments, and details are not repeated here.

本实施例提供的挂载处理方法，由于文件系统异常时，对外部存储设备挂载成功的可能性低，因此在前述实施例的基础上，本实施例通过判断外部存储设备的文件系统是否异常，可以判断挂载成功的可能性，从而在实际执行挂载操作前作出预判，并在文件系统异常时不进行挂载操作，可以节省资源，提高挂载效率。The mounting processing method provided in this embodiment, because when the file system is abnormal, the possibility of successfully mounting the external storage device is low, so on the basis of the foregoing embodiments, this embodiment judges whether the file system of the external storage device is abnormal , the possibility of successful mounting can be judged, so that a prediction can be made before the actual execution of the mounting operation, and the mounting operation will not be performed when the file system is abnormal, which can save resources and improve mounting efficiency.

另外，外部存储设备管理模块在判定外部存储设备的文件系统异常，并设置外部存储设备的挂载状态标识为无法挂载标识时，可以不执行挂载操作，但将无法挂载标识发送至存储管理服务模块，使得存储管理服务模块可以广播对应的挂载结果。具体地，请参阅图6，示出了本申请实施例提供的一种挂载处理方法，具体地，该方法包括：S601至S610。In addition, when the external storage device management module determines that the file system of the external storage device is abnormal, and sets the mount status flag of the external storage device as an unmountable flag, it may not perform the mount operation, but sends the unmountable flag to the storage device. The management service module enables the storage management service module to broadcast the corresponding mounting result. Specifically, please refer to FIG. 6 , which shows a mounting processing method provided by the embodiment of the present application. Specifically, the method includes: S601 to S610.

S601：存储管理服务模块向外部存储设备管理模块发送第一调用指令。S601: The storage management service module sends a first calling instruction to the external storage device management module.

S602：外部存储设备管理模块响应于第一调用指令，执行检测操作，且设置外部存储设备的检测状态标识为检测中标识，并返回检测状态标识。S602: The external storage device management module executes a detection operation in response to the first calling instruction, and sets the detection state flag of the external storage device as a detection state flag, and returns the detection state flag.

S603：外部存储设备管理模块在检测操作已完成时，向存储管理服务模块发送检测完成指令。S603: When the detection operation is completed, the external storage device management module sends a detection completion instruction to the storage management service module.

S604：存储管理服务模块响应于检测完成指令，向外部存储设备管理模块发送第二调用指令。S604: The storage management service module sends a second call instruction to the external storage device management module in response to the detection completion instruction.

S605：外部存储设备管理模块响应于第二调用指令，根据检测状态标识，判断外部存储设备的文件系统是否异常。S605: The external storage device management module determines whether the file system of the external storage device is abnormal according to the detection status flag in response to the second calling instruction.

于本实施例中，若非异常，可以执行S606；若异常，可以执行S608。In this embodiment, if it is not abnormal, S606 may be executed; if abnormal, S608 may be executed.

S609：外部存储设备管理模块在当前挂载已完成时，向存储管理服务模块发送挂载完成指令。S609: When the current mounting is completed, the external storage device management module sends a mounting completion instruction to the storage management service module.

于本实施例中，在当前挂载已完成时，向存储管理服务模块发送挂载完成指令，其中挂载完成指令包括挂载状态标识，使得存储管理服务模块在接收到挂载完成指令时，可以获取外部存储设备的挂载状态标识。In this embodiment, when the current mount is completed, send a mount completion instruction to the storage management service module, wherein the mount completion instruction includes a mount status identifier, so that when the storage management service module receives the mount completion instruction, The mount status identifier of the external storage device can be obtained.

其中，外部存储设备管理模块执行挂载操作对外部存储设备进行挂载后，可以获取挂载结果，于本实施例中，若外部存储设备管理模块判定外部存储设备的文件系统异常，设置外部存储设备的挂载状态标识为无法挂载标识，此时当前挂载已完成；若非异常，获取挂载结果，并根据挂载结果设置挂载状态标识，此时当前挂载也已完成。由于在文件系统异常时，外部存储设备管理模块仍将无法挂载标识发送至存储管理服务模块，使得存储管理服务模块对可以广播每次挂载外部存储设备时对应的挂载结果都可以广播，即便在文件系统异常时，未执行挂载操作，也将对应的挂载失败进行广播，使得其他应用程序可以及时获知所插入的外部存储设备的挂载状态。Wherein, after the external storage device management module executes the mount operation to mount the external storage device, the mount result can be obtained. In this embodiment, if the external storage device management module determines that the file system of the external storage device is abnormal, set the external storage device If the mount status of the device is marked as unable to mount, the current mount has been completed; if it is not abnormal, obtain the mount result and set the mount status flag according to the mount result, and the current mount has also been completed at this time. Because when the file system is abnormal, the external storage device management module will still send the unmountable flag to the storage management service module, so that the storage management service module can broadcast the corresponding mount result every time the external storage device is mounted, Even if the mount operation is not performed when the file system is abnormal, the corresponding mount failure will be broadcasted, so that other applications can know the mount status of the inserted external storage device in time.

S610：存储管理服务模块根据挂载状态标识，广播与挂载状态标识对应的挂载结果。S610: The storage management service module broadcasts a mounting result corresponding to the mounting state identifier according to the mounting state identifier.

作为一种实施方式，若挂载状态标识为无法挂载标识，存储管理服务模块广播挂载失败；若挂载状态标识为已挂载标识，存储管理服务模块广播挂载成功，使得系统上的应用程序可以访问挂载成功的外部存储设备。具体地，存储管理服务模块向系统广播挂载结果，应用程序监听到广播后可以作对应操作，例如，用于文件管理的应用程序可以在监听到挂载成功的广播时，在该应用程序的界面显示出该外部存储设备，并在监听到挂载失败的广播时，在该应用程序的界面显示该外部存储设备异常。As an implementation, if the mount status flag is unable to mount, the storage management service module broadcasts the mount failure; if the mount status flag is mounted, the storage management service module broadcasts the mount success, so that the Applications can access successfully mounted external storage devices. Specifically, the storage management service module broadcasts the mounting result to the system, and the application can perform corresponding operations after listening to the broadcast. For example, when an application for file management listens to the broadcast of successful mounting, it can The interface displays the external storage device, and when the mount failure broadcast is heard, the application interface displays that the external storage device is abnormal.

需要说明的是，上述步骤中未详细描述的部分，可参考前述实施例，在此不再赘述。It should be noted that, for parts not described in detail in the above steps, reference may be made to the foregoing embodiments, and details are not repeated here.

本实施例提供的挂载处理方法，在前述实施例的基础上，在外部存储设备管理模块检测到外部存储设备的文件系统异常后，不执行挂载操作，降低不必要的资源消耗，同时通过将无法挂载标识发送至存储管理服务模块，使得存储管理服务模块仍广播检测异常标识对应的挂载结果，使得其他应用程序可以及时获知当前挂载结果，提高响应效率，便于用户在挂载失败时及时采取措施，提升用户体验。The mounting processing method provided in this embodiment, on the basis of the foregoing embodiments, does not perform the mounting operation after the external storage device management module detects that the file system of the external storage device is abnormal, so as to reduce unnecessary resource consumption, and at the same time pass Send the mount failure flag to the storage management service module, so that the storage management service module still broadcasts the mount result corresponding to the abnormal detection flag, so that other applications can know the current mount result in time, improve the response efficiency, and facilitate the user when the mount fails Take timely measures to improve user experience.

另外，外部存储设备管理模块在判定外部存储设备的文件系统异常，并设置外部存储设备的挂载状态标识为无法挂载标识时，仍可以进行挂载操作，具体地，请参阅图7，示出了本申请实施例提供的一种挂载处理方法，具体地，该方法包括：S701至S710。In addition, when the external storage device management module determines that the file system of the external storage device is abnormal, and sets the mount status flag of the external storage device as an unmountable flag, the mount operation can still be performed.

作为一种实施方式，在检测时长超过预设时长时，外部存储设备管理模块也可以不中断检测操作，使得检测操作继续，继续对损坏的文件系统进行修复。具体地，在文件系统损坏过多时，外部存储设备管理模块要完成对所有异常的文件系统的修复，所需的时长较长，并且所需的时长可能超过预设时长，此时通过在检测时长超过预设时长时，仍不中断检测操作，使得外部存储设备管理模块可以对外部存储设备中损坏的文件系统继续进行修复，由此，存在在挂载操作执行前，完成修复的可能，此时检测操作未完成的外部存储设备仍具有可被成功挂载的可能。As an implementation manner, when the detection duration exceeds the preset duration, the external storage device management module may not interrupt the detection operation, so that the detection operation continues, and the damaged file system continues to be repaired. Specifically, when the file system is damaged too much, the external storage device management module needs to complete the repair of all abnormal file systems, which takes a long time, and the required time may exceed the preset time. When the preset duration is exceeded, the detection operation is still not interrupted, so that the external storage device management module can continue to repair the damaged file system in the external storage device. Therefore, there is a possibility that the repair can be completed before the mount operation is executed. At this time External storage devices whose detection operation has not been completed may still be successfully mounted.

S703：外部存储设备管理模块在检测操作已完成时，向存储管理服务模块发送检测完成指令。S703: When the detection operation is completed, the external storage device management module sends a detection completion instruction to the storage management service module.

若外部存储设备管理模块判定外部存储设备的文件系统异常，设置外部存储设备的挂载状态标识为无法挂载标识，仍可以进行挂载操作，继续执行S707。If the external storage device management module determines that the file system of the external storage device is abnormal, it sets the mount status flag of the external storage device as an unmountable flag, and the mount operation can still be performed, and continues to execute S707.

作为一种实施方式，在S707之前，外部存储设备管理模块将外部存储设备的文件系统修复完成，使得该文件系统恢复正常，此时，通过执行S707，可以使得由于在预设时长内未修复完成导致检测状态标识设置为检测异常标识的外部存储设备，在文件系统恢复正常时，可以及时进行挂载，而不需要重新插入、重新执行检测、挂载操作，因此提高了外部存储设备的挂载效率。As an implementation, before S707, the external storage device management module completes the repair of the file system of the external storage device, so that the file system returns to normal. The external storage device whose detection status flag is set as the detection abnormality flag can be mounted in time when the file system returns to normal without reinserting, re-executing detection, and mounting operations, thus improving the mountability of external storage devices. efficiency.

需要说明的是，上述步骤中未详细描述的部分，可参考前述实施例，在此不再赘述。It should be noted that, for parts not described in detail in the above steps, reference may be made to the foregoing embodiments, and details are not repeated here.

本实施例提供的挂载处理方法，通过在检测时长超过预设时长时，仍未中断检测操作，继续对损坏的文件系统进行修复，并在执行挂载操作，获取挂载结果前这段时间完成了修复，使得外部存储设备的文件系统恢复正常，从而本实施例通过外部存储设备管理模块在根据检测异常标识设置挂载状态标识为无法挂载后，仍可执行挂载操作，使得外部存储设备可以在文件系统恢复正常时及时被挂载，提高挂载效率。The mount processing method provided in this embodiment continues to repair the damaged file system without interrupting the detection operation when the detection duration exceeds the preset duration, and performs the mount operation during the period before obtaining the mount result The repair is completed, so that the file system of the external storage device returns to normal, so that in this embodiment, the external storage device management module can still perform the mount operation after setting the mount status flag as unmountable according to the detection abnormality flag, so that the external storage device The device can be mounted in time when the file system returns to normal, improving the mounting efficiency.
