NAME

       vgconvert - convert volume group metadata format

SYNOPSIS

       vgconvert  [-d|--debug] [-h|--help] [-t|--test] [-v|--verbose] [--labelsector] [-M|--metadatatypetype] [--pvmetadatacopies#copies] [--meta-
       datasizesize] [--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.

EXAMPLE

       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 ar-
       chive file to restore the original metadata.
