thin_delta  allows you to compare the mappings in two thin volumes (snapshots allow common blocks between
       thin volumes).

       This tool cannot be run on live metadata unless the --metadata-snap option is used.

--thin1,--snap1{natural}
              The numeric identifier for the first thin volume to diff.

       --thin2,--snap2{natural}
              The numeric identifier for the second thin volume to diff.

       --metadata-snap[blocknr]
              Use a metadata snapshot.

           If you want to get information out of a live pool then you will need to
           take a metadata snapshot and use this switch.  In order for the information
           to be meaningful, you need to ensure the thin volumes you're examining are
           not changing (ie, do not activate those thins).

       --verbose
              Provide extra information on the mappings.

       -h,--help
              Print help and exit.

       -V,--version
              Output version information and exit.
