4.10. Suspending Activity on a File System

You can suspend write activity to a file system by using the dmsetup suspend command. Suspending write activity allows hardware-based device snapshots to be used to capture the file system in a consistent state. The dmsetup resume command ends the suspension.


Start Suspension
dmsetup suspend MountPoint
End Suspension
dmsetup resume MountPoint
Specifies the file system.


This example suspends writes to file system /mygfs2.
# dmsetup suspend /mygfs2
This example ends suspension of writes to file system /mygfs2.
# dmsetup resume /mygfs2
