Thank you Clay! That makes sense! I wasn't aware that zones needed to be about the same size. The first 3 devices are going away. As the names might reveal they are running on software raid partitions which is a bad idea. So I guess some of the problem will correct itself when they are removed completely.
I'm using the official ubuntu packages so I'll have to wait until the commit makes it into those. At the moment the zones represent different servers (but same rack, DC). Is that a bad idea?
