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 {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.
