NAME
 vgconvert - convert volume group metadata format
SYNOPSIS
 vgconvert [-d|--debug] [-h|--help] [-t|--test] [-v|--verbose] [--labelsector] [-M|--metadatatypetype] [--metadatacopies#copies] [--metadatasizesize] [--version] VolumeGroupName [VolumeGroupName...]
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.
EXAMPLE
 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.
