|
|
- 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`
|
