My guess would be no, since /proc/mdstat gives less info than mdadm does. > how does mdadm know what devices to query if they are not defined in > /etc/mdadm/mdamd.conf with DEVICES? Don't know how, but since 'mdadm --detail --scan' provides the info you can use to create the mdadm.conf file when missing, mdadm obviously does not rely on getting its info from that file at all. > if devices are missing from the raid device, is there a way of knowing > the name of the missing device without the configuration file? Yes. Well, it depends on what you call "missing". It will report a failed etc device, but if the array was created with a 'missing' drive it obviously cannot know what device will get added before you actually add it. greetings, Maarten -- - 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
