In previous versions of triple-quickstart a config file was used to determine not only the features that would be enabled in tripleo and openstack but also the number of nodes to be used. For instance "config/general_config/ha.yml" would configure pacemaker and ensure three controller nodes were provisioned.This typeof configuration is now deprecated but will still work through the Queens release. The feature and node configuration have been seperated into two distinct configuration files to allow users to explicity select the configuration known as "feature sets" and the nodes to be provisioned. The feature set configuration can be found under tripleo-quickstart/config/general_config/ and the node configuration can be found under tripleo-quickstart/config/nodes/
In general,Ocata overcloud deployment is more memory consuming then Newton.Minimal memory requirements are highlighted bellow. Also minor trobleshooting step was undertaken after overcloud deployment. Command `pcs resource cleanup` was issued after detecting resources failed to start right after original deployment. Sshuttle command line was also modified to provide access to control plane and external network from workstation at a time.
