背景技术Background technique
随着计算机技术的发展，在云计算领域，超融合系统也随之发展。超融合虚拟化系统，简称超融合系统，是一种集成了虚拟计算资源和存储设备的信息基础系统。在超融合系统中，用户所使用的存储空间是利用软件构建的，这样就使得实体存储设备与用户之间保持隔离的状态，实现了实体存储资源与虚拟化平台的完整融合。With the development of computer technology, in the field of cloud computing, hyper-converged systems have also developed. Hyper-converged virtualization system, referred to as hyper-converged system, is an information infrastructure system that integrates virtual computing resources and storage devices. In a hyper-converged system, the storage space used by users is constructed using software, which maintains isolation between physical storage devices and users, achieving complete integration of physical storage resources and virtualization platforms.
超融合系统的功能之一是为用户提供存储服务，利用超融合系统能够将数据分散存储在多个独立的服务器上，能够满足大规模数据存储的需要。One of the functions of a hyper-converged system is to provide users with storage services. Using a hyper-converged system, data can be distributed and stored on multiple independent servers, which can meet the needs of large-scale data storage.
超融合系统中每一个服务器为一个节点，服务器内的存储资源例如物理磁盘等可以被超融合系统使用，以成为超融合系统包括的存储资源。但是当物理磁盘被超融合系统使用后，只向超融合系统反馈该物理磁盘的相关信息，不再向该物理磁盘实际所处的服务器反馈该物理磁盘的相关信息，导致服务器无法及时更新物理磁盘的相关信息。Each server in the hyper-converged system is a node, and the storage resources in the server, such as physical disks, can be used by the hyper-converged system to become storage resources included in the hyper-converged system. However, when a physical disk is used by a hyper-converged system, only the relevant information of the physical disk is fed back to the hyper-converged system, and the relevant information of the physical disk is no longer fed back to the server where the physical disk is actually located, resulting in the server being unable to update the physical disk in a timely manner. related information.

正如背景技术中所述，在实际应用中，经常会出现服务器中物理磁盘的更换、新增和删除等场景，当服务器中的物理磁盘被超融合系统使用后，物理磁盘的更换、新增和删除等只会对超融合系统进行反馈，对于服务器自身而言，在该服务器内的物理磁盘被超融合系统使用后，被超融合系统使用的物理磁盘不再向服务器自身进行反馈相关信息，经过一段时间后，若物理磁盘进行了信息更新，服务器不会收到更新的信息，导致服务器无法及时更新物理磁盘的相关信息，进而导致超融合系统中保存的对该服务器内包括的物理磁盘的信息和服务器自身保存的物理磁盘的信息不匹配。As mentioned in the background art, in actual applications, scenarios such as the replacement, addition, and deletion of physical disks in the server often occur. When the physical disks in the server are used by the hyper-converged system, the replacement, addition, and deletion of physical disks often occur. Deletion, etc. will only feedback to the hyper-converged system. As for the server itself, after the physical disk in the server is used by the hyper-converged system, the physical disk used by the hyper-converged system will no longer feed back relevant information to the server itself. After a period of time, if the information of the physical disk is updated, the server will not receive the updated information, causing the server to be unable to update the relevant information of the physical disk in a timely manner, which in turn causes the hyper-converged system to save information about the physical disk included in the server. It does not match the physical disk information saved by the server itself.
基于此，本申请实施例提供了一种超融合系统的信息同步方法，针对超融合系统中任意一个服务器，获取超融合系统在该服务器中包括的第一物理磁盘集合的信息以及该服务器存储的被超融合系统使用的第二物理磁盘集合的信息，对两个信息进行比较，得到该服务器内被超融合系统使用的物理磁盘的新增信息或删除信息，根据新增信息或删除信息，更新该服务器内被超融合系统使用的物理磁盘的存储信息，也就是说，对超融合系统内的磁盘信息和服务器内的磁盘信息进行比较，得到服务器内物理磁盘的新增信息或删除信息，使得服务器内的物理磁盘在被超融合系统使用后，依旧能够更新物理磁盘的相关信息，保持服务器内被超融合系统使用的物理磁盘的信息和超融合系统中包括的物理磁盘的信息的一致性，同时在服务器上正确显示被超融合系统使用的物理磁盘的信息，能够提高超融合系统的易用性和容错性，提高超融合系统的性能。Based on this, embodiments of the present application provide an information synchronization method for a hyper-converged system. For any server in the hyper-converged system, the information of the first set of physical disks included in the server of the hyper-converged system and the information stored by the server are obtained. Information on the second set of physical disks used by the hyper-converged system. Compare the two information to obtain new or deleted information on the physical disks used by the hyper-converged system in the server. Update the information based on the newly added or deleted information. The storage information of the physical disks used by the hyper-converged system in the server. In other words, the disk information in the hyper-converged system and the disk information in the server are compared to obtain the new information or deletion information of the physical disks in the server, so that After the physical disks in the server are used by the hyper-converged system, the relevant information of the physical disks can still be updated to maintain the consistency of the information of the physical disks used by the hyper-converged system in the server and the information of the physical disks included in the hyper-converged system. At the same time, correctly displaying the information of the physical disks used by the hyper-converged system on the server can improve the usability and fault tolerance of the hyper-converged system and improve the performance of the hyper-converged system.
参见图1，该图为本申请实施例提供的一种超融合系统的信息同步方法的流程图。Refer to Figure 1, which is a flow chart of an information synchronization method in a hyper-converged system provided by an embodiment of the present application.
在本申请实施例中，超融合系统包括一个或多个服务器，本申请实施例提供的超融合系统的信息同步方法，应用于服务器。In this embodiment of the present application, the hyper-converged system includes one or more servers. The information synchronization method of the hyper-converged system provided by the embodiment of this application is applied to the servers.
本实施例提供的超融合系统的信息同步方法包括如下步骤：The information synchronization method of the hyper-converged system provided by this embodiment includes the following steps:
S101，获取所述超融合系统包括的第一物理磁盘集合的第一磁盘集合信息和所述服务器存储的被所述超融合系统使用的第二物理磁盘集合的第二磁盘集合信息。S101. Obtain the first disk set information of the first physical disk set included in the hyper-converged system and the second disk set information of the second physical disk set used by the hyper-converged system stored in the server.
在本申请的实施例中，针对超融合系统中的任意一个服务器，该服务器包括的一个或多个物理磁盘被超融合系统使用，在超融合系统在该服务器初始化时，该服务器存储了被超融合系统使用的一个或多个物理磁盘的信息，即第二磁盘集合信息。第二物理磁盘集合为在超融合系统初始化阶段，服务器存储的被超融合系统使用的一个或多个物理磁盘。In the embodiment of this application, for any server in the hyper-converged system, one or more physical disks included in the server are used by the hyper-converged system. When the hyper-converged system is initialized on the server, the server stores the hyper-converged disk. The information of one or more physical disks used by the fusion system is the second disk set information. The second set of physical disks is one or more physical disks stored in the server and used by the hyper-converged system during the initialization phase of the hyper-converged system.
第二磁盘集合信息包括第二磁盘集合内的物理磁盘个数和物理磁盘的基础信息，基础信息至少包括物理磁盘的唯一标识(Small Computer System Interface ID，SCSIID)。基础信息还包括物理磁盘的盘符或绝对路径等磁盘的属性信息。The second disk set information includes the number of physical disks in the second disk set and basic information of the physical disks. The basic information at least includes a unique identifier (Small Computer System Interface ID, SCSIID) of the physical disk. Basic information also includes disk attribute information such as the drive letter or absolute path of the physical disk.
在本申请的实施例中，第一磁盘集合信息为超融合系统包括的第一物理磁盘集合的第一磁盘集合信息，即超融合系统也存储了在该服务器内被使用的一个或多个物理磁盘的信息。第一物理磁盘集合为超融合系统在该服务器包括的一个或多个物理磁盘。In the embodiment of the present application, the first disk set information is the first disk set information of the first physical disk set included in the hyper-converged system, that is, the hyper-converged system also stores one or more physical disks used in the server. Disk information. The first set of physical disks is one or more physical disks included in the server in the hyper-converged system.
在超融合系统在该服务器初始化之后，物理磁盘的新增或删除等都不再向服务器反馈，只向超融合系统进行反馈。After the hyper-converged system is initialized on the server, the addition or deletion of physical disks will no longer be fed back to the server, only to the hyper-converged system.
在经过一段时间之后，第一磁盘集合信息和第二磁盘集合信息可以相同，这反映在该段时间内，该服务器被超融合系统使用的物理磁盘没有任何变化。After a period of time, the first disk set information and the second disk set information may be the same, which reflects that there is no change in the physical disks used by the hyper-converged system on the server during the period of time.
但是在实际应用中，在经过一段时间之后，该服务器被超融合系统使用的物理磁盘可能会发生变化，例如删除、新增或更换等，超融合系统包括的第一磁盘集合内的物理磁盘的第一磁盘集合信息是最新的并且实时的信息，而由于服务器无法收到物理磁盘的反馈信息，服务器存储的依旧还是在超融合系统初始化时，被超融合系统使用的第二磁盘集合的第二磁盘集合信息，即当服务器内被超融合系统使用的物理磁盘发生变化时，第一磁盘集合信息和第二磁盘集合信息不同。However, in actual applications, after a period of time, the physical disks used by the hyper-converged system on the server may change, such as being deleted, added, or replaced. The physical disks in the first disk set included in the hyper-converged system may change. The first disk set information is the latest and real-time information. Since the server cannot receive feedback information from the physical disk, the server still stores the second disk set used by the hyper-converged system when the hyper-converged system is initialized. Disk set information, that is, when the physical disks used by the hyper-converged system in the server change, the first disk set information and the second disk set information are different.
在本申请的实施例中，可以通过调用虚拟化底层命令，获取当前超融合系统包括的第一物理磁盘集合的第一磁盘集合信息。第一磁盘集合信息包括一个或多个物理磁盘每个物理磁盘的基础信息，可以以列表的形式获取。In the embodiment of the present application, the first disk set information of the first physical disk set included in the current hyper-converged system can be obtained by calling the virtualization underlying command. The first disk set information includes basic information of each physical disk of one or more physical disks, which can be obtained in the form of a list.
在本申请的实施例中，直接在服务器本地获取服务器存储的被超融合系统使用的第二物理磁盘集合的第二磁盘集合信息。In the embodiment of the present application, the second disk set information of the second physical disk set used by the hyper-converged system stored in the server is directly obtained locally on the server.
S102，对比所述第一磁盘集合信息和所述第二磁盘集合信息，确定所述服务器内被所述超融合系统使用的物理磁盘的插拔信息，所述插拔信息为所述物理磁盘的新增信息或删除信息。S102: Compare the first disk set information and the second disk set information to determine the plug-in and plug-out information of the physical disk used by the hyper-converged system in the server. The plug-in and plug-out information is the plug-in and plug-in information of the physical disk. Add new information or delete information.
在本申请的实施例中，通过对比第一磁盘集合信息和第二磁盘集合信息，能够确定服务器内被超融合系统使用的物理磁盘的插拔信息，其中，物理磁盘的插拔信息为物理磁盘的新增信息或删除信息。也就是说，由于超融合系统包括第一磁盘集合信息是最新的并且实时的物理磁盘的信息，通过对比第一磁盘集合信息和第二磁盘集合信息，就能够确定服务器上被超融合系统使用的物理磁盘的变化，是新增了物理磁盘或删除了物理磁盘。更换物理磁盘被视为删除原有的物理磁盘，新增一个物理磁盘。In the embodiment of the present application, by comparing the first disk set information and the second disk set information, the plug-in and pull-out information of the physical disks used by the hyper-converged system in the server can be determined, where the plug-and-pull information of the physical disks is the physical disk Add information or delete information. That is to say, since the hyper-converged system includes the latest and real-time physical disk information of the first disk set information, by comparing the first disk set information and the second disk set information, it can be determined that the server is used by the hyper-converged system. Changes in physical disks include the addition of new physical disks or the deletion of physical disks. Replacing a physical disk is regarded as deleting the original physical disk and adding a new physical disk.
具体比对第一磁盘集合信息和第二磁盘集合信息可以通过以下的方式：Specifically, the first disk set information and the second disk set information can be compared in the following ways:
可以判断第一物理磁盘集合包括的物理磁盘是否同时属于第二物理磁盘集合，若不属于，则该物理磁盘是服务器内被超融合系统新增使用的物理磁盘。It can be determined whether the physical disks included in the first physical disk set also belong to the second physical disk set. If not, the physical disk is a new physical disk in the server that is used by the hyper-converged system.
接下来继续判断第二物理磁盘集合包括的物理磁盘是否同时属于第一物理磁盘集合，若不属于，则物理磁盘是服务器内被超融合系统删除使用的物理磁盘。Next, it is continued to determine whether the physical disks included in the second physical disk set also belong to the first physical disk set. If not, the physical disk is a physical disk in the server that has been deleted and used by the hyper-converged system.
通过上述方式比对第一磁盘集合信息和第二磁盘集合信息，能够确定服务器上新增或删除的物理磁盘。By comparing the first disk set information and the second disk set information in the above manner, the newly added or deleted physical disks on the server can be determined.
由于第一磁盘集合信息包括第一物理磁盘集合内的物理磁盘的基础信息，第二磁盘集合信息包括第二物理磁盘集合内的物理磁盘的基础信息，因此，可以通过判断第一物理磁盘集合内的物理磁盘的唯一标识是否同时属于第二磁盘集合信息，即判断第一物理磁盘集合内的物理磁盘的唯一标识是否同时在第二物理磁盘集合信息出现，来具体判断第二物理磁盘集合包括的物理磁盘是否同时属于第一物理磁盘集合；可以通过判断第二物理磁盘集合内的物理磁盘的唯一标识是否同时属于第一磁盘集合信息，即判断第二物理磁盘集合内的物理磁盘的唯一标识是否同时在第一物理磁盘集合信息出现，来具体判断判断第二物理磁盘集合包括的物理磁盘是否同时属于第一物理磁盘集合。Since the first disk set information includes the basic information of the physical disks in the first physical disk set, and the second disk set information includes the basic information of the physical disks in the second physical disk set, it can be determined by Whether the unique identifier of the physical disk also belongs to the second disk set information, that is, it is judged whether the unique identifier of the physical disk in the first physical disk set also appears in the second physical disk set information to specifically determine whether the second physical disk set includes Whether the physical disks belong to the first physical disk set at the same time; you can determine whether the unique identifiers of the physical disks in the second physical disk set also belong to the first disk set information, that is, determine whether the unique identifiers of the physical disks in the second physical disk set are At the same time, when the first physical disk set information appears, it is specifically determined whether the physical disks included in the second physical disk set also belong to the first physical disk set.
S103，根据所述插拔信息，更新所述服务器内被所述超融合系统使用的物理磁盘的存储信息。S103: Update the storage information of the physical disk used by the hyper-converged system in the server according to the plug-in information.
在本申请的实施例中，根据对比第一磁盘集合信息和第二磁盘集合信息得到的物理磁盘的插拔信息，更新服务器内被超融合系统使用的物理磁盘的存储信息。In the embodiment of the present application, the storage information of the physical disks used by the hyper-converged system in the server is updated based on the physical disk insertion and removal information obtained by comparing the first disk set information and the second disk set information.
服务器内被超融合系统使用的物理磁盘的存储信息存储在数据库中，存储信息包括服务器与物理磁盘的对应关系，服务器包括的物理磁盘的基础信息和使用信息，其中，使用信息为物理磁盘是否被超融合系统使用的信息。The storage information of the physical disks used by the hyper-converged system in the server is stored in the database. The storage information includes the correspondence between the server and the physical disks, the basic information and usage information of the physical disks included in the server, where the usage information is whether the physical disk is used. Information used by hyperconverged systems.
在本申请的实施例中，若插拔信息为服务器内被超融合系统使用的物理磁盘的新增信息，则新增服务器与新增使用的物理磁盘的对应关系以及新增使用的物理磁盘的基础信息。也就是说，若服务器内被超融合系统使用的物理磁盘为新增的物理磁盘，则需要在数据库中添加服务器与新增的物理磁盘的对应关系以及新增的物理磁盘的基础信息，以通过数据库反映在服务器中新增加物理磁盘被超融合系统使用。具体添加对应关系可以是在数据库表中插入新增加物理磁盘的记录，添加新增的物理磁盘的基础信息可以在数据库表的关联表中进行添加，该关联表为新增的物理磁盘的表。In the embodiment of the present application, if the plugging and unplugging information is new information about the physical disk used by the hyper-converged system in the server, then the corresponding relationship between the newly added server and the newly used physical disk and the relationship between the newly used physical disk and basic information. That is to say, if the physical disk used by the hyper-converged system in the server is a newly added physical disk, you need to add the corresponding relationship between the server and the new physical disk and the basic information of the new physical disk in the database to pass The database is reflected in the newly added physical disks in the server being used by the hyper-converged system. Specifically, adding a corresponding relationship can be by inserting a record of a newly added physical disk into a database table. Basic information about adding a newly added physical disk can be added in an association table of the database table. The association table is the table of the newly added physical disk.
在本申请的实施例中，若插拔信息为服务器内被超融合系统使用的物理磁盘的删除信息，则删除服务器与删除使用的物理磁盘的对应关系以及删除使用的物理磁盘的基础信息。也就是说，若服务器初始化时被超融合系统使用的物理磁盘为删除的物理磁盘，则需要在数据库中删除服务器与删除的物理磁盘的对应关系以及删除的物理磁盘的基础信息，以更新数据库存储的在服务器中被超融合系统使用的物理磁盘的信息。具体首先在数据库中删除数据库表的关联表，该关联表为删除的物理磁盘的表，之后在数据库中删除服务器与删除的物理磁盘的对应关系，删除对应关系可以是删除数据库表中删除的物理磁盘的记录。In the embodiment of the present application, if the plugging and unplugging information is the deletion information of the physical disk used by the hyper-converged system in the server, the corresponding relationship between the deletion server and the deletion of the used physical disk and the basic information of the deletion of the used physical disk are deleted. That is to say, if the physical disk used by the hyper-converged system when the server is initialized is a deleted physical disk, the corresponding relationship between the server and the deleted physical disk and the basic information of the deleted physical disk need to be deleted in the database to update the database storage Information about the physical disks used by hyperconverged systems in the server. Specifically, first delete the association table of the database table in the database, which is the table of the deleted physical disk, and then delete the corresponding relationship between the server and the deleted physical disk in the database. The deletion of the corresponding relationship may be to delete the deleted physical disk in the database table. Disk records.
在本申请的实施例中，在更新服务器内被超融合系统使用的物理磁盘的存储信息之后，服务器可以扫描本地的物理适配器，得到当前服务器上包括的物理磁盘的基础信息，以及物理磁盘的个数等，并将这些信息同步至数据库中。In the embodiment of the present application, after updating the storage information of the physical disks used by the hyper-converged system in the server, the server can scan the local physical adapter to obtain the basic information of the physical disks currently included on the server, as well as the individual physical disks. data, etc., and synchronize this information to the database.

Since physical disk C was previously in server 2, the record of the new physical disk C has been stored in the database, so there is no need to add the new record of physical disk C again. You only need to modify the corresponding relationship between physical disk C and server 2 as follows The corresponding relationship between physical disk C and server 1 is to modify the table association relationship of physical disk C and associate physical disk C with server 1.
针对服务器2而言，获取服务器2的第一磁盘集合信息和第二磁盘集合信息，第一磁盘集合信息为物理磁盘A和物理磁盘D的信息，第二磁盘集合信息为物理磁盘C和物理磁盘D的信息，通过对比第一磁盘集合信息和第二磁盘集合信息，确定物理磁盘A为在服务器1中被超融合系统新增的物理磁盘，物理磁盘C为在服务器1中被超融合系统删除的物理磁盘。由于之前将物理磁盘C与服务器1的对应关系修改为物理磁盘C与服务器2的对应关系，物理磁盘C已经不处于服务器2中，因此只对物理磁盘A进行新增，由于之前物理磁盘A在服务器1中，已经在数据库中存储过新增物理磁盘A的记录，因此无需再次添加物理磁盘A的新增的记录，只需要修改物理磁盘A和服务器1的对应关系为物理磁盘A和服务器2的对应关系，具体的是修改物理磁盘A的表关联关系，将物理磁盘A与服务器2进行关联。For server 2, obtain the first disk set information and the second disk set information of server 2. The first disk set information is the information of physical disk A and physical disk D, and the second disk set information is physical disk C and physical disk Based on the information of D, by comparing the first disk set information and the second disk set information, it is determined that physical disk A is a physical disk added by the hyper-converged system in server 1, and physical disk C is deleted by the hyper-converged system in server 1. physical disk. Since the corresponding relationship between physical disk C and server 1 was previously modified to the corresponding relationship between physical disk C and server 2, physical disk C is no longer in server 2, so only physical disk A is added. Since physical disk A was previously in In Server 1, the record of the new physical disk A has already been stored in the database, so there is no need to add the new record of the physical disk A again. You only need to modify the corresponding relationship between the physical disk A and the server 1 to be the physical disk A and the server 2. The corresponding relationship is to modify the table association relationship of physical disk A and associate physical disk A with server 2.
