In case it helps, it is recognizing the partitions, sdd2 and sdb2
the new RAID is to be assembled from:

And it does recognize the other partitions, sdd1 and sdb1, outside
the RAID, that reside on those disks. I can mount them and they
have their proper contents. So it is detecting the gpt partitioning
properly.
