Gluster client can't connect to Gluster volume

Do you have any firewall rules enabled? I'd start by disabling iptables 
(or at least setting everything to ACCEPT) and as someone else suggested 
setting selinux to permissive/disabled.

Why are your nodes and client using different versions of Gluster? 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.
