In order to be successfull with vgcfgrestore you need to a) figure out the most recent metadata backup which *doesn't* contain information about the snapshot in question (you can do that with the -ll and the -f option of the vgcfgrestore command on the files in /etc/lvmconf/NameOfYourVG*) *and* b) run "pvcreate -ff" on all the PVs before vgcfgrestore *and* c) run vgcfgrestore on *all* of the PVs of your VG in question > > > > > And if vgcfgrestore helps, what if you create a snapshot and then some > > other vgs and lvs and then your snapshot gets corrupt like this, can > > vgcfgrestore help here also? > > > > So I would say I'm out. :-( > > > > > Is there a way to remove the snapshot (the volumegroup can't be made > > > active) without touching the other logical volumes ? > > > > Would be really interesting to know the answer. > > > > > _______________________________________________ > 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.
