In a similar situation, I booted from the DVD in "linux rescue" mode. I 
found that when it asked whether I wanted it to find and mount 
partitions, I needed to hit "skip".  If I allowed it to mount the root 
partition, I could not unmount it.

In rescue mode, the vgscan, etc commands are not directly present, but
the executable lvm is, which can do all those things. When you run lvm,
you will get a new prompt, where you type lvm commands.
