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.<br>
<br>
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.<br>

<div>Hi, All:<br>

I've built a Gluster-based storage cluster on a pair of CentOS
5.7 (i386) VM's. The nodes are using Gluster 3.2.6 (from
source) and the host is using Gluster 3.0.0 (from the Mageia
package repositories):</div>

<div>None of the systems (i.e., neither the two storage nodes
nor the client) can connect to Port 6996 of the cluster (<span

mount the shared volume using the Gluster helper and/or NFS:</div>
