背景技术Background technique

分布式文件存储系统在IT企业、云计算、大数据以及虚拟化等领域得到了广泛应用。与此同时，这些领域对存储系统的目录自精简功能的要求也越来越高，仅提供给用户目录自精简功能，但不兼容硬盘系统容量，已无法满足存储系统的使用，还需要能够让目录自精简能够根据用户自身使用需求，修改自精简分配，动态适配并兼容硬盘系统容量。由于目前分布式文件系统目录自精简无法修改预分配，更无法动态兼容硬盘系统容量，降低了存储系统的健壮性、易用性以及功能的丰富性，并严重影响分布式文件存储产品的竞争力。Distributed file storage systems are widely used in IT enterprises, cloud computing, big data, and virtualization. At the same time, these fields have higher and higher requirements for the directory self-reduction function of the storage system.

启动自精简预分配，根据配置的客户端地址参数对客户端进行集群挂载；Start the self-thinning pre-allocation, and perform cluster mounting on the client according to the configured client address parameters;

获取集群系统时间，记录时间戳，在挂载目录创建文件夹；Obtain the cluster system time, record the timestamp, and create a folder in the mount directory;

对创建的文件夹设置预分配空间大小，通过挂载目录查询硬盘系统总空间，对比预分配空间以及系统总空间的大小，选择是否对自精简进行设置。Set the pre-allocated space size for the created folder, query the total hard disk system space through the mounted directory, compare the pre-allocated space and the total system space, and choose whether to set self-thinning.

通过icfs-fs-snap–off关闭文件快照服务，在存储系统主节点的 /home/snap目录下的snap_conf配置文件中，新增snapShot_status文件快照服务标志位参数，并置snapShot_status参数值为OFF。Turn off the file snapshot service through icfs-fs-snap–off, add the snapShot_status file snapshot service flag parameter in the snap_conf configuration file under the /home/snap directory of the storage system master node, and set the snapShot_status parameter value to OFF.

通过icfs-admin-quota–stop–dir关闭目录配额服务，然后在/home/quota目录下的dirquota_conf配置文件中，新增dirQuota_status目录配额服务标志位参数，并置dirQuota_status为OFF。Turn off the directory quota service through icfs-admin-quota–stop–dir, then add the dirQuota_status directory quota service flag parameter in the dirquota_conf configuration file under the /home/quota directory, and set dirQuota_status to OFF.

在查询并确保snapShot_status参数以及dirQuota_status参数均已成功修改为OFF后，通过icfs-fs-thin–start启动自精简功能。After querying and ensuring that the parameters snapShot_status and dirQuota_status have been successfully changed to OFF, start the self-thinning function through icfs-fs-thin–start.
