Following up on this message, I don’t want anyone to think I’m asking for help without doing my own research.
I found a set of instructions at http://www.barryodonovan.com/index.php/2007/12/08/lvm-recovery and it’s similar to my problem (although my physical volume is on a partition instead of the entire disk) and I want to make sure that the plan to repair my system won’t wipe existing data.
So, assuming the data is still on /dev/sdc1, if I recreate the PV, will I lose data? i.e., will pvcreate –vvvv –u <my uuid> /dev/sdc1 destroy the data on the partition?
Similiarly, will vgcreate –v <my volumename> /dev/sdc1 kill my data?
Am I heading in entirely the wrong direction?

I’m hoping I can get some help recovering my data. A week or so back I accidentally overwrote the partition table on one of the two drives containing my data. I luckily didn’t touch the partition itself, so I believe all the data is still there, but in rebuilding the partition table I (think I) nuked the uuid of the drive. Now I’m not sure how to progress.
Please help this relative neophyte – there is a lot of nostalgia sitting on those drives. Tell me what information you need and I will get it.
