[Gluster-users] Gluster client can't connect to Gluster volume

Thanks, David:

But I'd rather see if I can fix the problem with the Mageia client (glusterfs-client-3.0.0-2.mga1):
	* This will allow me to file a bug report with the package maintainer (if necessary).
	* I already know that the systems that have Gluster 3.2.6 from source [i.e., the storage nodes] are able to mount the volume.
	* I'd rather keep my daily-driver (i.e., the host system) 100% Mageia.

    don't think anyone expects 3.2 and 3.0 to work correctly.

                    port 6996 comes from - Gluster uses 24007 for it's
                    core communications and ports above that for
                    individual bricks.
