AFAIK, the current production glusterfs doesn't support replicated striped
volumes. This is due to be added in 3.3 (now in beta):

Of course, a replicated *distributed* volume exists. The difference is that
a distributed volume puts each file entirely on one disk of the set, whilst
a striped volume puts chunks of each files on each disk.

I don't really understand the question. For a replicated distributed volume
where the data is replicated N times, you have to add N bricks at a time; I
would imagine the same will be true of a replicated striped volume.
