Based on the above, I'd say your md0 is still mounted as a filesystem.
umount it, or if you're having real problems getting it umounted add
noauto to fstab options for the fs and the next boot shouldn't mount it
and raidstop will work fine.

If it's not mounted, and you're getting the above errors, please send
df output.
