DESCRIPTION         top

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

OPTIONS         top

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

Examples         top

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

       vgconvert -M2 vg1

RECOVERY         top

       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.
