If a file system is no longer used and needs to be deleted, you are advised to unmount the file system and then delete it.
Before unmounting a file system, stop the process and read/write operations.
umount Local path
Local path: An ECS local directory where the file system is mounted, for example, /local_path.
Before running the umount command, stop all read and write operations on this file system and exit the local path. Otherwise, the unmount operation will fail.
