NAME

thin_dump − dump thin provisioning metadata from device or file to standard output

SYNOPSIS

thin_dump [options] {device|file}

DESCRIPTION

thin_dump dumps binary thin provisioning metadata (optionally from alternate block; see option −−metadata-snap) created by the device-mapper thin provisioning target on a device or file to standard output for analysis or postprocessing in either XML or human readable format. XML formated metadata can be fed into thin_restore (see thin_restore(8)) in order to put it back onto a metadata device (to process by the device-mapper target) or file.
−f, −−format {xml|human_readable}
Print output in XML or human readable format.
−r, −−repair
Repair the metadata whilst dumping it.
−m, −−metadata_snap [block#]
Dump metadata snapshot created by device-mapper thin provisioning target. If block is not provided, access the default metadata snapshot created by the thin provisioning device-mapper target, else try the one at block#. See the thin provisioning target documentation on how to create or release a metadata snapshot and retrieve the block number from the kernel.
−h, −−help
Print help and exit.
−V, −−version
Output version information and exit.

EXAMPLES

Dumps the thin provisioning metadata on logical volume /dev/vg/metadata to standard output in human readable format:

thin_dump -f human_redable /dev/vg/metadata

Dumps the thin provisioning metadata on logical volume /dev/vg/metadata to standard output in XML format:

thin_dump /dev/vg/metadata

Dumps the thin provisioning metadata snapshot on logical volume /dev/vg/metadata to standard output in human readable format (not processable by thin_restore(8) ):

thin_dump --format human_readable --metadata-snap /dev/vg/metadata

DIAGNOSTICS

thin_dump returns an exit code of 0 for success or 1 for error.
