Yes, you will want to dd the backing device.

Seeing as LVM is atop DRBD, I don't think you will be able to go through
with this without cloning the LVM stuff. But then, I don't see how this
is problematic, either.

You will end up with the LVM -> DRBD -> LVM "sandwich". Myself, I'm not
particularly fond of the concept, but it's known to work quite well.

Good luck,
Felix
