You haven't provides a lot of concrete information, like error messages
during boot or "mdadm -E" output of devices or even kernel/mdadm versions, so
I can only guess, but my guess would be that you can fix it by assembling
the array with "--update=homehost"
i.e.
mdadm --assemble /dev/mdwhatever \
--update=homehost /dev/device1 /dev/device2 ....
