I don't mean gone as in removed, I mean changed as in adding/removing a drive in a system that should not cause these problems. The Xyratex gear I'm using should allow me to add/remove drives while the system is running, as in hot swap. I'm guessing it's the Xyratex I need to work on some more. Still, I do want to understand how to deal with hardware changes so that I don't have crashed clusters too often since we do change/move gear in and out, a lot.
