NAME
       vgconvert - convert volume group metadata format

SYNOPSIS
       vgconvert  [--commandprofile  ProfileName] [-d|--debug] [-h|--help] [-t|--test] [-v|--ver‐
       bose] [--labelsector] [--bootloaderareasize size] [-M|--metadatatype type]  [--pvmetadata‐
       copies  NumberOfCopies]  [--metadatasize  size]  [--version] VolumeGroupName [VolumeGroup‐
       Name...]

DESCRIPTION
       vgconvert converts VolumeGroupName metadata from one format to another provided  that  the
       metadata fits into the same space.

OPTIONS
       See lvm(8) and pvcreate(8) for options.

Examples
       Convert volume group vg1 from LVM1 metadata format to the new LVM2 metadata format.

       vgconvert -M2 vg1

RECOVERY
       Use  pvscan(8)  to see which PVs lost their metadata.  Run pvcreate(8) with the --uuid and
       --restorefile options on each such PV to reformat it as it was,  using  the  archive  file
       that vgconvert(8) created at the start of the procedure.  Finally run vgcfgrestore(8) with
       that archive file to restore the original metadata.
