If you need to take a hardware-based snapshot of an XFS file system, you can temporarily stop write operations to it.
You do not need to explicitly suspend write operations if you use the lvcreate command to take an LVM snapshot.
To freeze and unfreeze an XFS file system, use the -f and -u options with the xfs_freeze command, for example:
#xfs_freeze -f /myxfs# # ... Take snapshot of file system ... #xfs_freeze -u /myxfs
You can also use the xfs_freeze command with
btrfs, ext3, and
ext4 file systems.
For more information, see the xfs_freeze(8)
manual page.
