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;)
