DESCRIPTION¶
vgconvert converts VolumeGroupName metadata from one format to another
provided that the metadata fits into the same space.
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.
