thin_delta - Print the differences in the mappings between two thin devices.
thin_delta [options] {device|file}
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.
--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.
