Is this possible? How can Reco's answers contradict that. Reco's answers echoed pretty much exactly what I would have said. If you don't know how to get from those answers to exactly what you want then you need to be a lot more precise in the requirements. There is a mdadm mode with no metadata at all. check the --build option. I've never used it though... But as Reco suggested, easiest and safest is probably to make space for the superblock.
