It would be interesting to see what the mdadm --detail /dev/mdX says.
I see the VG is made out of 1 PV md3? What are md0,1,2 doing, I can guess md0 is probably /boot, but what about 1 and 2?
It wouldn't hurt to give the sfdisk partition dumps for the drives in question too.

Thanks for the reply. md2 is /boot, md0 is /root and md1 is swap.
