The backup GPT is located in about the same place as the mdadm v2 metadata. So one can step on the other, depending on how the array is created (on whole devices or on partitions). The problem with unwinding this is if any of these structures becomes stale without having the signature wiped, it becomes important to find out for certain which one is valid and which one is stale. > >> Are these two drives on the same >> controller? > > yes afaict I'd check all the cables (the connections in particular) drive to controller and that the controller is seated. Seems sorta unlikely you'd have the same kind of problem on two drives at the same time that's a hardware problem unless they share something the other drives don't; or if some event has modified both drives the same way. Thing is, invalid argument during seek for read? Kinda sounds like a hardware problem. -- Chris Murphy
