I was thinking that, but I wasn't sure of the approach to this problem.

We're currently running 2.4.18-27 XFS enabled kernel. I'm not having a
huge issue with all this, but the damn qlogic drivers we use keep
shitting the bed on us. I'm not 100% sure why just yet, but something's
afoot here. So, in an effort to have/get support for all pieces we're
using, I was looking at potentially using RHAS 2.1. At least, at some
level, we could know that this "configuration" *should* work. If it
doesn't then it expands our troubleshooting capabilities so each
organization RH/Dell/Oracle, can offer their aid as well.

Our bigger issue is the 2500/server/year support cost, plus NO XFS
support. Bah..screw that!
