Did you do an "mdadm --stop /dev/md1" before trying that? That's a classic error from an array that's previously been partially assembled and failed ...
The other thing I'd do is make sure there aren't any other unepected partially assembled arrays. I doubt it applies here, but I have come across mirrors that get broken in half and you get two failed arrays instead of one working one ...
