Use "mdadm --examine" on various component devices to discover the uuid or e.g. mdadm --examine --scan --config=partitions Once you have determined a particular UUID use e.g. mdadm --assemble /dev/mdX --update=super-minor --uuid=ebe07606:c0b4c223:3f00e978:949a6a60 /dev/sd*a This will find all devices with the right uuid, assemble them in /dev/mdX (you choose X) and update the superblock to reflect the correct md number.
