I am trying to mount this (my old hard drive) from my Centos 5 install as a USB drive so I can copy files over.
I have made the change to max_luns so that I can have more than one drive on a USB drive.
The first partition, /dev/sda1 mounts automatically as /boot_
The second partition, /dev/sda2 is the one I really want and it is an lvm partition. When I am booted from this drive (as the installed IDE drive, not as a usb drive) has for its /etc/fstab:
# This file is edited by fstab-sync - see 'man fstab-sync' for details /dev/VolGroup00/LogVol01 / ext3 defaults 1 1 LABEL=/boot /boot ext3 defaults 1 2 none /dev/pts devpts gid=5,mode=620 0 0 none /dev/shm tmpfs defaults 0 0 /dev/VolGroup00/LogVol02 /home ext3 defaults 1 2 none /proc proc defaults 0 0 none /sys sysfs defaults 0 0 /dev/VolGroup00/LogVol00 swap swap defaults 0 0
But I do not see any /dev/Vol... when I boot from my Centos 5 drive (oh, I have labeled the lvm partitions on that drive to start with Centos5 so that its labels are different from my Centos 4 drive lablels).
What mount command do I use?

vgscan ; vgchange -ay VolGroup00
If the volume group happens to be the same as the one you're using on your new system, then that will probably fail, and I suggest renaming your current volume group using a rescue cd (don't forget to recreate the initrd, as it has the vg hardcoded).

I will give this a try, shortly.
If the volume group happens to be the same as the one you're using on your new system,
I was careful to give the new drive a different name than the old one.... So I suspect I am set for this.
then that will probably fail, and I suggest renaming your current volume group using a rescue cd (don't forget to recreate the initrd, as it has the vg hardcoded).
