either of which would make the ZFS designers pace back and forth in
their Tower muttering angrily.  zvol's are meant for things like iSCSI
and Xen only, not for hosting some other filesystem when you could
just use ZFS instead.  (and ZFS does not itself run on top of zvol's.)

Also, you are discouraged from using more software RAID underneath ZFS
because ZFS can do the job better itself.  For example ZFS can tell if
one side of a mirror is silently corrupting data because of some bad
PATA cable or something, and read from the other side.  gmirror can't
do that, nor can ZFS if there is a gmirror under it.  I guess using
geli would be ok---that tool is missing from Solaris for now.
