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

Sat May 5 12:44:41 UTC 2012

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.
