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;) --=20 Best regards, Ken Gunderson GPG Key-- 9F5179FD "Freedom begins between the ears." -- Edward Abbey
