I'm hoping there's an LVM guru out there who can help with this one. I added an old disk to my system because I needed some temporary space. After creating a partition that used the entire disk, I added the partition as a physical volume (PV) to the volume group (VG) that already occupied most of the first disk. I then created a logical volume (LV) of the entire PV on the second disk. When I tried creating the file system on the new LV, I had so many errors during the bad block check that I decided not to use it. I did not, however, remove it from the VG, Now, the second disk has died completely, so much so that it even prevents the BIOS from seeing the first disk when booting. The problem is that when I try to boot with just the first disk, it says that LVM is badly screwed up and the kernel panics. I was able to boot with the distro's (CentOS 4.0) rescue CD and even started an lvm shell which has all the LVM commands, but it appears they all need to have to the volume group available (under /dev) which it isn't because it is screwed up. Any ideas on how I can remove the LV and PV for the second disk from the VG so I can get my life back in order? TIA, Eric P.S. This is LVM 2.
