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
