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.
