I can't say this with 100% certainty but I would of thought that it would been fine. I've lost my mdadm.conf (reinstalled OS) with a separate 4 disk RAID 5 array and re-assembled the array and carried on as if nothing had happened. Use "sudo mdadm -E --scan" do get a list of discovered RAID devices like this example: ARRAY /dev/md0 level=raid0 num-devices=2 UUID=fde94900:3f3f3bf6 Pop the results in your mdadm.conf and that should sort you out after a reboot (I think). Also try something like "sudo mdadm --assemble /dev/md1 /dev/sdb1 /dev/sdc1" to assemble the RAID manually. -- Regards, James ;) Pablo Picasso - "Computers are useless.
