I suspect a kernel upgrade would do the trick, though you don't say what kernel you are running. You could probably kick it along by removing and re-adding your spare: mdadm /dev/md_d0 --remove /dev/sdao mdadm /dev/md_d0 --add /dev/sdao (And I assume you mean 'raid5' rather than 'raid6', not that it matters..)
