3.11. 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.

Usage

Start Suspension

gfs_tool freeze MountPoint

End Suspension

gfs_tool unfreeze MountPoint

MountPoint: Specifies the file system.

Examples

This example suspends writes to file system /gfs.

gfs_tool freeze /gfs

gfs_tool unfreeze /gfs
