This post is an update for "Setting up Two Physical-Node OpenStack RDO Havana + Neutron GRE + Gluster backend for Cinder" on Fedora 20 boxes with both Controller and Compute nodes each one having one Ethernet adapter. It’s 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.
