(/dev/sda and /dev/sdc are fine.) So the immediate problem here is fixing the GPT partition table. Strictly, that isn't a RAID1 problem and I don't think it's appropriate to ask for comment on that issue on the raid list; people here are truly helpful so I'll fix the partition but I could use a comment on whether I should then just use the mdadm -- manage .. --add .. commands and whether mdadm needs to be inhibited from taking any automatic remedial action. regards, Ron
