Solved. It seems that I had not correctly copied the /boot partition (or maybe messed up the MBR). I cleaned the MBR and /boot, copied and reinstalled Grub on the clone drive and it worked! I was able to unplug the main drive, plug in the clone and the system booted without any problem. LVM is great in providing a live snapshot. But it was a pain to get around the VolGroup identical names due to clonage.
