The problem is that both /dev/sdd and /dev/sdd1 contains a MD
superblock for an array with the same UUID ; when I formatted the disk
and created the partition, it obviously didn't properly removed the
original md superblock.

So now md is confused and doesn't restart automatically.

I tried to modify /etc/mdadm/mdadm.conf so it only looks in the
appropriate partition ; this helps starts the raid drive from the
command line without error ; but not so after a reboot.

Tad annoying...
