Hi all I run a 4 disk array with 6 RAID 1 partitions. This is a very simple configurations which has served me well through multiple drive failures. I now have a wierd problem. One of the disks has become a critical node. My server does not boot without this disk no matter which disk is my primary boot disk (bios). I've changed the order of the disks and it makes no difference. When this disk is not in booting from some of the other disks gives me a warning that there is an invalid superblock magic on sda. They all end up with an error on stdin and modprobe failing. Any ideas how to resolve this? I'm leaning towards nukeing sd[acd] and re-adding them. -- Regards Wayne -- 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
