9.10. Suspending Activity on a File System

All write activity to a file system can be suspended for a time by using the gfs_tool command's freeze action. The unfreeze action returns the file system to its ordinary state. That feature allows hardware-based device snapshots to be used to capture the file system in a consistent state.
