Not really an answer to your question, I got a snapshot of the in development driver that seems to work just fine. I haven't run smartctl on the controller much mind you, as it seems to freak out my onboard controller too (AMD SB750). I could attempt it, but I've recently just switched over to that hardware for my main server, and I'm reluctant to try running smartctl on the array, as it'd probably require a reboot to get which ever disk back that might get dropped. I might try it later, but I don't even have smartmontools installed. > -- Kristleifur > -- > To unsubscribe from this list: send the line "unsubscribe linux-raid" in > the body of a message to majordomo@xxxxxxxxxxxxxxx > More majordomo info at http://vger.kernel.org/majordomo-info.html > -- Thomas Fjellstrom tfjellstrom@xxxxxxx -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
