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