This I think, highlights one of glusters few weaknesses - the inflexibility of brick layout. It would be really nice if you could just arbitrarily add bricks to distributed-replicate volumes and have files be evenly distributed among them as a whole. This would work particularly well with sharded volumes. Unfortunately I suspect this would need some sort of meta server.
Setups with arbiters especially. I know it's a relatively new feature still, however all of the tools for managing & manipulating dist-rep layouts are geared for standard bricks. It's very easy to accidentally convert your arbiters into full rep 3 bricks.
Luckily, most situations where you want to grow your cluster from a basic setup, you'll be converting to true rep 3 anyway.
