7       vices.

SYNOPSIS

10       thin_delta [options] {device|file}
11
12

DESCRIPTION

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

OPTIONS

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