thin_dump
[options]
{device|file}
thin_dump
dumps binary thin provisioning metadata (optionally from alternate block;
see option –metadata-snap) created by the device-mapper

in order to put it back onto a metadata
device
(to process by the device-mapper target) or
file.

thin_dump -f human_redable /dev/vg/metadata
Dumps the thin provisioning metadata on logical volume /dev/vg/metadata
