To write a new/repaired pv_header and label_header: pvck --repairtype pv_header --file <file> <device> This uses the metadata input file to find the PV UUID, device size, and data offset. To write new/repaired metadata text and mda_header: pvck --repairtype metadata --file <file> <device> This requires a good pv_header which points to one or two metadata areas. Any metadata areas referenced by the pv_header are updated with the specified metadata and a new mda_header. "--settings mda_num=1|2" can be used to select one mda to repair. To combine all header and metadata repairs: pvck --repair --file <file> <device> It's best to use a raw metadata file as input, that was extracted from another PV in the same VG (or from another metadata area on the same PV.) pvck will also accept a metadata backup file, but that will produce metadata that is not identical to other metadata copies on other PVs and other areas. So, when using a backup file, consider using it to update metadata on all PVs/areas. To get a raw metadata file to use for the repair, see pvck --dump metadata|metadata_search. List all instances of metadata from the metadata area: pvck --dump metadata_search <device> Save one instance of metadata at the given offset to the specified file (this file can be used for repair): pvck --dump metadata_search --file <file> --settings "metadata_offset=<off>" <device>	2019-11-27 11:13:47 -06:00
