You did make a new mdadm.conf with the correct devices for each array
right? If not try running and seeing if your arrays come up. If they
do then copy /tmp/mdadm.conf to /etc/mdadm/mdadm.conf
mdadm --examine --scan --config=partitions > /tmp/mdadm.conf
mdadm --assemble --scan --config=/tmp/mdadm.conf
