3.9. Suspending Activity on a GFS2 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.

Usage

Start Suspension

dmsetup suspend MountPoint

End Suspension

dmsetup resume MountPoint

MountPoint: Specifies the file system.

Examples

This example suspends writes to file system /mygfs2.

# dmsetup suspend /mygfs2

This example ends suspension of writes to file system /mygfs2.

# dmsetup resume /mygfs2
