File System Defragmentation*

If your data is modified constantly, the amount of fragmented files will increase in the file system, resulting in slow access performance of files on the hard drives. Performing file system defragmentation can improve the performance.

To perform file system defragmentation:

Open Storage Manager.
Go to Volume.
Select the volume on which to perform file system defragmentation.
Click Manage.
Select File system defragmentation.

Note:

File system defragmentation can only be performed on volumes in Btrfs file system.
File system defragmentation can only be performed when the status of the volume is Normal.
Please do not shut down the system before file system defragmentation is completed. If the system is shut down before completion, file system defragmentation must be restarted from the beginning.
Volume usage might increase if the volume contains snapshots of shared folders.
