Thanks, David:

That's fine. If it's just a version-mismatch I can accept that. I'm sure that the developers at Mageia are working on catching-up in Mageia, Version 2. I just figured that, if it were a version-mismatch, I'd see something to that effect in the servers' log files. That's all.

                    3.0 to work correctly.

                                    not just use the 3.2.6 version for
                                    everything? Also, I'm not sure where
                                    port 6996 comes from - Gluster uses
                                    24007 for it's core communications
                                    and ports above that for individual
                                    bricks.
