No. You need to "pvcreate -ff" your PVs and vgcfgrestore a metadata backup to all of them. Before doing so, you can save your actual metadata for recovery in case something goes badly wrong with: for d in /dev/hda[34] do dd if=$d of=$(basename $d).vgda bs=1k count=1k done So, assuming /dev/hda[34] are all your PVs which belonged to the missing VG (otherwise add those), figure out the recent metadata backup in /etc/lvmconf. Say /etc/lvmconf/VG.conf would be the one. Then run: pvcreate -yff /dev/hda[34] vgcfgrestore -n YourVGName /dev/hda3 vgcfgrestore -n YourVGName /dev/hda4 vgscan vgchange -ay > vgcreate gives: > vgcreate -- ERROR: "/etc/lvmtab" doesn't exist; please run vgscan > and pvscan gives: > pvscan -- reading all physical volumes (this may take a while...) > pvscan -- inactive PV "/dev/hda3" is associated to an unknown VG (run vgscan) > pvscan -- inactive PV "/dev/hda4" is associated to an unknown VG (run vgscan) > pvscan -- total: 2 [16.88 GB] / in use: 2 [16.88 GB] / in no VG: 0 [0] > > Where do I go from here - vgcfgrestore? uuid_fixer? Even something really smelly! Please upgrade to LVM 1.0.3 and do the pvcreate + vgcfgrestore above. > Thanks, > Bill > (Sorry if this comes over a bit garbled, I'm posting using lynx, 'coz > pine's somewhere on /dev/hda4 ...) > > > _______________________________________________ > linux-lvm mailing list > linux-lvm@sistina.com > http://lists.sistina.com/mailman/listinfo/linux-lvm > read the LVM HOW-TO at http://www.sistina.com/lvm/Pages/howto.html -- Regards, Heinz -- The LVM Guy -- *** Software bugs are stupid.
