This is FC5, the old FC3 (What is left of it.) is on /dev/hdb. Partition 1
on hdb is the boot partition, partition 2 on hdb is the LVM where my stuff
is at:

You know, knoppix might not be a bad idea. I will try it later, have to go
to work now.

Yeah but make sure you don't change file permissions, uids, gids on either
FC3 or FC5. Major headaches if that happens..

I hear ya.

Will try that when I get home later. Thanks for the advice.

You can see the hdb partitions using fdisk on FC5
Are you sure you can't mount the hdb2 now on FC5?
I mean case closed if you can mount FC3 on FC5

root@ $ mount -t ext3 -o ro,defaults /dev/hdb2 /mnt/fc3sys


I didn't mention it first because using
$ vgextend volgroup /dev/hdb2
should have added FC3 as an extension to your FC5 volgroup
but you should be able to turn off lvm vgchange -an.

$ man vgchange

root@ $ vgchange -an # turns off lvm

root@ $ shutdown -r now

root@ $ mount -t ext3 -o ro,defaults /dev/hdb2 /mnt/sysfc3

root@ $ cp -a /mnt/sysfc3/whatever /home/whatever

root@ $ vgchange -an # turns lvm back on

root@ $ shutdown -r now
