thin_dump
THIN_DUMP(8) System Manager's Manual THIN_DUMP(8)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-map-
per 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 process-
able 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.
