SYNOPSIS

       vgconvert    [--commandprofile   ProfileName]   [-d|--debug]   [-h|--help]   [-t|--test]   [-v|--verbose]
       [--labelsector] [--bootloaderareasize size] [-M|--metadatatype type] [--pvmetadatacopies  NumberOfCopies]
       [--metadatasize size] [--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.

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.
