Right. This is consistent with what I've seen as well.
I can't help you repair this filesystem, but when you do my suggestion
remains to change the partition types of the RAID members. This is
because I've noticed that the in-kernel RAID detection and assembly code
sometimes gets it wrong (leading to the kinds of symptoms you've
reported), whereas mdadm run from the initrd does not.
