This is nonsense. Mdadm creates those nodes automa[tg]ically - man mdadm, search for --auto. Udev has exactly nothing to do with mdX nodes. In order for an md array to be started up on boot, it has to be specified in /etc/mdadm.conf. With proper DEVICE line in there. That's all. If you're using raid0 on top of two raid1s (as opposed to using raid10 directly - which is more efficient and flexible), the DEVICE line in mdadm.conf should be either `partitions' (usually preferred way), or - in case direct device list is specified - should contain both real disks AND the raid1 arrays. But in any case, this has exactly nothing to do with kernel. It's 100% userspace issues, I'd say distribution-specific issues. /mjt - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
