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
