I happen to have just received my first Coraid chassis. I am planning
on testing it out later this week with software raid, lvm, and reiser.
If there is a particular config someone would like to know about, I
might be able to try it out before putting this system into production.
Heck, you might steer me toward something I like better than my current
plan.
