NAME

6       thin_delta  -  Print  the  differences in the mappings between two thin
7       devices.

SYNOPSIS

10       thin_delta [options] {device|file}
11

DESCRIPTION

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

OPTIONS

20       --thin1, --snap1 {natural}
21              The numeric identifier for the first thin volume to diff.
22
23       --thin2, --snap2 {natural}
24              The numeric identifier for the second thin volume to diff.
25
26       --metadata-snap [block nr]
27              Use a metadata snapshot.
28
29           If you want to get information out of a live pool then you will need to
30           take a metadata snapshot and use this switch.  In order for the information
31           to be meaningful, you need to ensure the thin volumes you're examining are
32           not changing (ie, do not activate those thins).
33
34
35       --verbose
36              Provide extra information on the mappings.
37
38       -h, --help
39              Print help and exit.
40
41       -V, --version
42              Output version information and exit.
