If nothing is changing and the order is swapping really every boot, then IMO that is odd. But it's very normal for ordering to change from time to time, and definitely when elements change - kernel version/flavor, drivers, BIOS settings, etc. Part of my SOP is now to record both mdadm and the boot loader's ordering against serial number and UUID of drives when creating an array, and to put the relevant information on labels securely attached to the physical drives, along with creating a map of their physical location and taping that inside the case. It's critical to know what's what in a crisis. . . -- 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
