Besides, it stops a MDS if the sfcfsd daemon and node are running.
Only a superuser can perform unmount processing.

Specifies the name of path name of the block special file of a representative partition of the file system to be unmounted.
Specifies the directory of the mount point of the file system that will be unmounted.
<EXAMPLES>

<NOTES>
When the secondary MDS does not exist, the GFS Shared File System should be unmounted on the node which the primary MDS is running after it is unmounted on other nodes. Or, the GFS Shared File System should be unmounted at the same time on all nodes by using sfcumntgl(8). If the GFS Shared File System is unmounted first on the node which the primary MDS is running, the file system will be blockaded on other nodes.
