3.10. 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.

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
