Generally most of these systems have a dedicated metadata server where for
each file they store on which servers(replicas) the file is stored. In
gluster there is no metadata server, while it gives flexibility in some
other ways, In this aspect it becomes a bit rigid. The steps I gave above
eventually achieve the same thing. Another way to solve this problem is to
flip the order of replication and distribution layers but that will need a
lot of subsystems to be tested thoroughly.
