VGCONVERT(8)                                   System Manager's Manual                                   VGCONVERT(8)



NAME
       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]
       [--reportformat {basic|json}] [--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.
