Ugh.  So I need to change my fstab file.  I swear, some expert on IRC
told me that this should work fine, which is why I did it.  In fact, I
think they recommended it on the basis that I wanted to put VM images
on one of the subvolumes.  This discussion occurred a long time ago,
well before RAID5 was even partially implemented.

There is still data redundancy.  Will a scrub at least notice that the
copies differ?
