THIN_DELTA(8)                                  System Manager's Manual                                  THIN_DELTA(8)



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
              The numeric identifier for the first thin volume to diff.


       --thin1, --snap1
              The numeric identifier for the second thin volume to diff.


       -m, --metadata-snap [block#]

              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 (eg, 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.
