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.
