If I switch the "DEVICE partitions" with "DEVICE /dev/sdb1 /dev/sdc1 /dev/sdd1", drives no longer are allocated as spares, however the array still seems to rebuild every boot.
I don't remember the specifics of what was in /proc/mdstat at the time, but currently the array is being rebuilt. I'll reboot after it is complete to give you a copy of it. Basically it allocated the dropped drive as a spare which I'd have to mdadm -stop and mdadm -add to the original array after every boot, manually. Give me an hour or two and I'll get you the output of mdstat.
