[linux-lvm] help! system crash ...

Hi everyone it seems im in a pinch.

my system crashed last night... system disk dead!  So i replaced it, unfortunately i lost all of the /etc/lvm data.

I rebuilt my system.. (RH 8.0) and it seemed to go well.  For some reason when i try to bring my LVM back up  it croaks and dies.

Here is the output... it looks like somehow /dev/hdc got messed up and has no PE's on it anymore.  How can i get it back?  Remember i dont have any of the backups because my system hard drive was wasted!

can i just re-create it? it was just one big disk, with a very simple layout.  How can i do that and keep the integrity of the other PV's?

any help would be VERY appreciated... 

bill
