     NAME
          thin_delta - Print the differences in the mappings between
          two thin devices.

     SYNOPSIS
          thin_delta [options] {device|file}

     DESCRIPTION
          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.

     OPTIONS
          --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 [block nr]
               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.
