Which is exactly why I *like* SW RAID - I can, and do, have the mirrors span controllers so a whole controller can fail without taking down the system. With HW RAID cards, if your controller dies, you're SOL. - 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
