Problem

How to use the pvck command: Check and repair LVM metadata on physical volumes. More information: <https://manned.org/pvck>.

Solution

pvck — Check and repair LVM metadata on physical volumes. More information: <https://manned.org/pvck>.

Print LVM on-disk headers and structures (label, PV header, MDA header, metadata area):

sudo pvck {{/dev/sdXN}} --dump headers

Print the current VG metadata text:

sudo pvck {{/dev/sdXN}} --dump metadata

List all metadata versions found in the metadata area:

sudo pvck {{/dev/sdXN}} --dump metadata_all

Search common locations for metadata when headers may be damaged, and save it to a file:

sudo pvck {{/dev/sdXN}} --dump metadata_search {{[-f|--file]}} {{path/to/metadata.txt}}

Select the second metadata area (mda2) when printing metadata:

sudo pvck {{/dev/sdXN}} --dump metadata --settings "mda_num=2"

Repair headers and metadata using a metadata input file (use with care):

sudo pvck {{/dev/sdXN}} --repair {{[-f|--file]}} {{path/to/metadata_file}}

Repair only the PV header and label header:

sudo pvck {{/dev/sdXN}} --repairtype pv_header
