Thanks, David:
Yes...
* iptables has been disabled on all three systems.
* SELinux is set to permissive on the two systems that employ it - the two CentOS nodes.
* Port #6996 is referenced in the Troubleshooting section of the Gluster User Guide.
FWIW: All of this except the SELinux question is already documented in my post on the Mageia Forum.

Why 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.
