It's fooled Garret into believing he had a > raid5, how many others are also using ata believing their raid5 is a > raid5. We should warn people in the future rather than just saying 'its > in the docs'. A kernel warning at attach is much more visible. Although it is more visible, personally I would prefer it to just fail instead of proceeding. RAID5 is not RAID5 without parity so why even allow it to continue and hence risk such an unrecoverable situation?
