So the vendors of the failing drives claimed that these kernels were supported? That's great, most vendors don't even consider Linux supported. What response did you get when you reported the problem to Redhat on your RHEL support contract? Did they agree that this hardware, and its use for software raid, was supported and intended? > Of all people, I would think you would > appreciate that.

It didn't properly cope with future hardware, and since you have very long uptimes, I'm reasonably sure you haven't updated the kernel to get fixes installed. -- bill davidsen CTO TMR Associates, Inc Doing interesting things with small computers since 1979
