     NAME
          thin_rmap - output reverse map of a thin provisioned region
          of blocks from metadata device or file.

     SYNOPSIS
          thin_rmap [options] {device|file}

     DESCRIPTION
          thin_rmap outputs the reverse mapping stored in the metadata
          on a device or file between a region of thin provisioned
          pool blocks and the associated thin provisioned devices.

          This tool cannot be run on live metadata.

     OPTIONS
          -h, --help
               Print help and exit.

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

          --region {block range}
               Specify range of blocks on the data device.

              At least one region must be specified.  Multiple regions may be specified.

              The range takes the format <begin>..<one past the end>.  For example,
              "5..45" specifies data blocks 5 to 44 inclusive, but not 45.

     EXAMPLES
          $ thin_rmap --region 5..45 /dev/pool-metadata

     DIAGNOSTICS
          thin_rmap returns an exit code of 0 for success or 1 for
          error.
