It'd be interesting to see mdadm -E for sdc and sdd. GPT uses LBA 0-3. And mdadm metadata 1.2 is 4K from the start. These do not overlap. So I'm unconvinced that mdadm -C applied to sdc and sdd instead of sdc1 and sdd1 is the source of the problem. Further, gdisk specifically said the GPT header was corrupt. The PMBR, LBA 0, is intact, and the table data (LBA 2) is intact. Only LBA 2 was stepped on by something? What do you get for gdisk -l /dev/sdc? Another warning or is it OK? Also for what it's worth: primary, extended, logical are terms that do not apply to GPT partitioned disks. There is only one kind of partition with GPT disks, no distinctions. -- Chris Murphy -- 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
