LVM2 not accessible unless using rescue disk.

I think I had a power failure while away with Fedora Core 10. This system has two LVM volumes. One is a data volume that consists of a hardware raid setup and the other is just one drive (this volume contains myths tv recordings).

The system looked up and running but I couldn't access MythTV. I rebooted it, and when it came back up it failed trying to mount the LVG that contains the TV shows, it also simply stated that the RAID01 LVG had "Failed". It recommended trying a different super block on the TVShows LVG. I ran the e2chfs on TVShows after setting the new super block and it still won't boot.

If I use a rescue disk or UBCD rescue disk, I can mount the LVG's just fine and browse the file systems.

the pvscan won't running from my original linux install. So.... I decided to try and spin MythDora 12.23 and hit upgrade thinking some of the binaries got corrupted. Same problem as before. It keeps thinking I have a corrupt/missing super block on TVShows LVG and says "Failed" on the RAID01 LVG.

Should I reinstall, or is there a way to recover this system? My data "looks" intact. In fact the only volume I was messing with for super block was TVShows so if that gets lost not the end of the world.

I think I found out what happened. The file system corrupted and couldn't mount a couple of the volumes. I lost most of the data on TVShows LVG and decided after looking that the system wasn't worth saving if that data was corrupted. I rebuilt it and was able to mount and acess all the files in the raoid01 volume which is what I care about.

Thanks for the reply though!
