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.
