Unmounting GPFS remote mount on compute nodes

Learn how to unmount GPFS filesystem from compute nodes.

To perform some GPFS administration tasks, you must first unmount the file system.

You can unmount a GPFS file system by using the cloudkit revoke filesystem command.

To unmount a GPFS file system by using the revoke command, enter the following line:

#./cloudkit revoke filesystem

Example:

#./cloudkit revoke filesystem
