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
