This looks like a nice geom based config:)  My question was about
gvinum though.  Vinum is more complex, but I think also allows for more
flexibility, albeit at a price.  I, too, have been using some
gmirror configs on 5.3 for a while now w/ zero problems.  And I have
simulated drive failures.  Works like a charm;)

Recently, however, I just bit the bullet and scored an LSI-320-2X...  A
sister machine is also in the works in near future, so maybe I'll build
it w/ a geom base raid10 config and have some fun playing;)
