NAME

       vgconvert - convert volume group metadata format

SYNOPSIS

       vgconvert    [-d|--debug]    [-h|--help]    [-t|--test]   [-v|--verbose]   [--labelsector]
       [-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.
