NAME
       vgconvert - convert volume group metadata format

SYNOPSIS
       vgconvert  [-d|--debug]  [-h|--help]  [-t|--test]  [-v|--verbose]  [--labelsector] [-M|--metadatatypetype] [--pvmetadata-
       copies#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.
