After I booted up on the CentOS 4.4 live CD, the LV's where both there, I
just needed to mount them. And BTW, I tried the snapshot thing, it worked
flawlessly. I tarred a backup then removed the LV of the snapshot. Now
my next step is to see if I can actually restore the whole system on my
test box. I also tarred the hda1 which is mounted as /boot. If this all
goes well, I won't ever have to bring the system down for DD backups
anymore.
