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. -- Rich
