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..)
