3.10. Suspending Activity on a File System

You can suspend write activity to a file system by using the gfs2_tool freeze command. Suspending write activity allows hardware-based device snapshots to be used to capture the file system in a consistent state. The gfs2_tool unfreeze command ends the suspension.

Usage

Start Suspension

gfs2_tool freeze MountPoint

End Suspension

gfs2_tool unfreeze MountPoint

MountPoint: Specifies the file system.

Examples

This example suspends writes to file system /mygfs2.

gfs2_tool freeze /mygfs2

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

gfs2_tool unfreeze /mygfs2
