Well the logs only show that separate hard drives stoped responding for a while and kernel resetted sata link at that point. Since it's happening on random drives, and even two at a time, I'd say hard drives itself are not the problem. I'd replace power supply first. I've had similar simptoms on one of my machines - it either crashed or kicked one of drives out of the array. It happened randomly, but usually once per month - who knows, maybe a spike in a grid, sudden cpu usage or something similar caused it. Anyway - bigger power supply solved the problem. -- Miha -- 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
