I had exactly the same problem and the same thoughts but I really don't=20 know how to delete a snapshot of an inactive volumegroup and I couldn't=20 find any program that was provided and did the job. Perhaps you can recover = some old configurations without snapshot with vgcfgrestore and stuff. But=20 I'm not really sure if this works cause the problem went away after I=20 rebooted the machine and was never to be seen again. And I was happy and=20 didn't touch this system again. And if vgcfgrestore helps, what if you create a snapshot and then some=20 other vgs and lvs and then your snapshot gets corrupt like this, can=20 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 ?
