As of the Red Hat Enterprise Linux 6 release, you can use the --merge option of the lvconvert
command to merge a snapshot into its origin volume. One use for this feature is to perform system
rollback if you have lost data or files or otherwise need to restore your system to a previous state. After
you merge the snapshot volume, the resulting logical volume will have the origin volume's name, minor
number, and UUID and the merged snapshot is removed. For information on using this option, see
Section 4.4.5, “Merging Snapshot Volumes”.
