       vgconvert - convert volume group metadata format

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.
