Your mileage may definitely vary, but neither of the servers on which I run mdadm have motherboards which allow mdadm to recognize the drives. For both of them, only drives 0 and 1 are properly recognized by Linux. I had to purchase SATA controllers for both. Both are Asus AMD-64 motherboards. -- 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
