Unmounting a file system

Some GPFS™ administration tasks require you to unmount the file system before they can be performed. You can unmount a GPFS file system using the mmumount command.

If the file system does not unmount, see File system fails to unmount.

To unmount a GPFS file system using the mmumount command, enter: 
mmumount device
where device is the name of the file system. For example, to unmount the file system fs1, enter: 
mmumount fs1
