I haven't run mdadm in ages, but it almost sounds like a raid was
accidentally created inside another raid.
The kernel assembled the raw devices into /dev/md1. However, when
mount checked the contents of /dev/md1 it found a raid member
signature instead of a filesystem. That suggests that /dev/md1 is one
component of a larger raid (which might only have one device in it).
That almost certainly isn't what was intended. I wouldn't be
surprised if it is possible to do by accident though.
