Setup Gluster 3.4.2 on Two Node Controller&Compute; Neutron GRE+OVS Fedora 20 Cluster

This post is focused on Gluster 3.4.2 implementation including tuning /etc/sysconfig/iptables files on Controller and Compute Nodes. Copying ssh-key from master node to compute, step by step verification of gluster volume replica 2 functionality and switching RDO Havana cinder services to work with gluster volume created to store instances bootable cinders volumes for performance improvement. Of course creating gluster bricks under “/” is not recommended . It should be a separate mount point for “xfs” filesystem to store gluster bricks on each node.
