3.6. Suspending an XFS File System

To suspend or resume write activity to a file system, use the following command:

# xfs_freeze mount-point

Suspending write activity allows hardware-based device snapshots to be used to capture the file system in a consistent state.

To suspend (that is, freeze) an XFS file system, use:

# xfs_freeze -f /mount/point

To unfreeze an XFS file system, use:

# xfs_freeze -u /mount/point

When taking an LVM snapshot, it is not necessary to use xfs_freeze to suspend the file system first. Rather, the LVM management tools will automatically suspend the XFS file system before taking the snapshot.

For more information about freezing and unfreezing an XFS file system, see man xfs_freeze.
