SYNOPSIS

11       thin_delta [options] {device|file}

DESCRIPTION

15       thin_delta allows you to compare  the  mappings  in  two  thin  volumes
16       (snapshots allow common blocks between thin volumes).
17
18       This  tool  cannot  be  run on live metadata unless the --metadata-snap
19       option is used.

OPTIONS

23       --thin1, --snap1
24              The numeric identifier for the first thin volume to diff.
25
26
27       --thin1, --snap1
28              The numeric identifier for the second thin volume to diff.

31       -m, --metadata-snap [block#]
32
33              If you want to get information out of a live pool then you  will
34              need  to take a metadata snapshot and use this switch.  In order
35              for the information to be meaningful you need to ensure the thin
36              volumes  you're  examining are not changing (eg, do not activate
37              those thins).
38
39
40       --verbose
41              Provide extra information on the mappings.
42
43
44       -h, --help
45              Print help and exit.
46
47
48       -V, --version
49              Output version information and exit.
