4.12. Suspending Activity on a File System

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


Start Suspension
gfs_tool freeze MountPoint
End Suspension
gfs_tool unfreeze MountPoint
Specifies the file system.
