I got a new cable, recreated the LV and copied everything over.
Rebooted, and was still getting the drive errors on boot, still getting
the drive light on solid, all of the problems I was having. To

Swapped drives (after the first drive failed).
Swapped cables
Swapped controllers (was originally on the first controller with the   
   other drive, now on the second.)

The original drive (Quantum) was known good prior to starting to use
LVM, it has since failed. (It had, among other things, a Debian mirror
on it.) The replacememt drive is known good as well, no errors on the
drive itself.

vg00 on /dev/hda works fine, no problems encountered. vg01 (/dev/hdb)
has problems. It is allowing me to turn off the vg (vgchange -a n),
however, any operations done on that vg afterwards (including attempting
to try to turn it back on results in a segmentation fault. (see earlier
message in this thread for the exact trap information).

Can someone give me any advice on what to do to fix this problem?

If you push the stick forward, the houses get bigger. If you pull
the stick back, they get smaller. That is, unless you keep pulling
the stick all the way back, then they get bigger again.
