Partition type FD is only for metadata 0.90 arrays to be auto-assembled 
by the kernel. This is now deprecated; you should be using partition 
type DA (Non-FS data) and an initrd to assemble your arrays.

Metadata version 0.90 does not support devices over 2TiB. I think it's a 
bug that you weren't warned at some point.

Cheers,

John.
