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 archive file to restore the original metadata.
