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  de-
       vice  or  file between a region of thin provisioned pool blocks and the
       associated thin provisioned devices.

       This tool cannot be run on live metadata.

       --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
