One of my LVM partitions is not mounted/does not shows up

This is what happened.
Created partitions, some of them LVM, in a server, say A.
Did the same for another server, B, but created one more LVM partition.

Installed RHEL in A, and some other applications.
Made dump files for each partition of A and restored all of them them in B.
No error in that process, except B wouldn't boot.
Did chroot /mnt/sysimage and grub-install /dev/sda--still no good.
B came to a halt with GRUB> dispalyed.
<tried many things many times.. searching Googles..but w/o luck)
Gave up, and restored the bootloader part using OS CD -- I say restored because now B boots ok and I can see application that I had installed in A.
So far so good.

Problem: that extra LVM partition is missing!
I did not knowingly overwrite it, so where did it go?
Somebody is keeping it from being displayed!

Is it the grub.conf that tells the OS what to mount and what not to?
If yes, problem is , grub.conf is missing in B. In A, it is in /boot/grub/.

df -kh shows other partions (some of them LVM) just fine.. what is going on?

I tracked a file called menu.lst in a strange place, in /usr/share/doc/grub-0.97.. but I didn't see any entry that loads partitions.

Would appreciate some advice, hint, urls. etc.

Thank you.

Using LVM is going to complicate what your trying to accomplish. I would recommend using a tool like CloneZilla to clone A to B in one pass instead of in chunks.
