RE: 1 disk shelf with 1 head....using just aggr0 - toasters

      Good advice - forgot about that one...
To make matters worse, the wafl check in question (when root vol is
involved) must first run on the underlying aggr, THEN on each volume
contained within it.  That is indeed serious down time, as the point of
an aggr is large number of disks (which means lots of empty space to
fill with data).

Between the two above arguments, there aren't a lot of reasons not to
put it all together.
One other reason I came up with: you cannot run wafl iron on rootvol or
on an aggregate containing the rootvol on a live system. I once had to
run wafl iron on a 4 shelf single aggr R200, and it was a _long_
downtime.
