I'm trying to create a RAID5 consisting of 4 3TB drives from scratch:

there's something I'm missing here - please advise.
In-kernel auto-assembly is only supported for metadata 0.90, and even then the feature is deprecated. If you have your root filesystem on a md array, use an initrd with mdadm in it to start it.
