In this section explain the purpose of the scenario and the + types of capabilities provided + +The purpose of os-nosdn-kvm-ha scenario testing is to test the +High Availability deployment and configuration of OPNFV software suite +with OpenStack and without SDN software. This OPNFV software suite +includes OPNFV KVM4NFV latest software packages for Linux Kernel and +QEMU patches for achieving low latency. High Availability feature is achieved +by deploying OpenStack multi-node setup with 3 controllers and 2 computes nodes + +KVM4NFV packages will be installed on compute nodes as part of deployment. +This scenario testcase deployment is happening on multi-node by using +OPNFV Fuel deployer. + +Scenario Components and Composition +----------------------------------- +.. In this section describe the unique components that make up the scenario, +.. what each component provides and why it has been included in order +.. to communicate to the user the capabilities available in this scenario. + +This scenario deploys the High Availability OPNFV Cloud based on the +configurations provided in ha_nfv-kvm_heat_ceilometer_scenario.yaml. +This yaml file contains following configurations and is passed as an +argument to deploy.py script + +* ``scenario.yaml:`` This configuration file defines translation between a + short deployment scenario name(os-nosdn-kvm-ha) and an actual deployment + scenario configuration file(ha_nfv-kvm_heat_ceilometer_scenario.yaml) + +* ``deployment-scenario-metadata:`` Contains the configuration metadata like + title,version,created,comment. + +* ``stack-extensions:`` Stack extentions are opnfv added value features in form + of a fuel-plugin.Plugins listed in stack extensions are enabled and + configured. + +* ``dea-override-config:`` Used to configure the HA mode,network segmentation + types and role to node assignments.These configurations overrides + corresponding keys in the dea_base.yaml and dea_pod_override.yaml. + These keys are used to deploy multiple nodes(3 controllers,2 computes) + as mention below. + + * **Node 1**: This node has MongoDB and Controller roles. The controller + node runs the Identity service, Image Service, management portions of + Compute and Networking, Networking plug-in and the dashboard. The + Telemetry service which was designed to support billing systems for + OpenStack cloud resources uses a NoSQL database to store information. + The database typically runs on the controller node. + + * **Node 2**: This node has Controller and Ceph-osd roles. Ceph is a + massively scalable, open source, distributed storage system. It is + comprised of an object store, block store and a POSIX-compliant distributed + file system. Enabling Ceph, configures Nova to store ephemeral volumes in + RBD, configures Glance to use the Ceph RBD backend to store images, + configures Cinder to store volumes in Ceph RBD images and configures the + default number of object replicas in Ceph. + + * **Node 3**: This node has Controller role in order to achieve high + availability. + + * **Node 4**: This node has Compute role. The compute node runs the + hypervisor portion of Compute that operates tenant virtual machines + or instances. By default, Compute uses KVM as the hypervisor. + + * **Node 5**: This node has compute role. + +* ``dha-override-config:`` Provides information about the VM definition and + Network config for virtual deployment.These configurations overrides + the pod dha definition and points to the controller,compute and + fuel definition files. + +* os-nosdn-kvm-ha scenario is successful when all the 5 Nodes are accessible, + up and running + +Scenario Usage Overview +----------------------- +.. Provide a brief overview on how to use the scenario and the features available to the +.. user. This should be an "introduction" to the userguide document, and explicitly link to it, +.. where the specifics of the features are covered including examples and API's + +* The high availability feature can be acheived by executing deploy.py with + ha_nfv-kvm_heat_ceilometer_scenario.yaml as an argument. +* Install Fuel Master and deploy OPNFV Cloud from scratch on Hardware + Environment: + + -Example: + +.. code:: bash + + sudo python deploy.py -iso ~/ISO/opnfv.iso -dea ~/CONF/hardware/dea.yaml -dha ~/CONF/hardware/dha.yaml -s /mnt/images -b pxebr -log ~/Deployment-888.log.tar.gz + +* Install Fuel Master and deploy OPNFV Cloud from scratch on Virtual + Environment: + + -Example: + +.. code:: bash + + sudo python deploy.py -iso ~/ISO/opnfv.iso -dea ~/CONF/virtual/dea.yaml -dha ~/CONF/virtual/dha.yaml -s /mnt/images -log ~/Deployment-888.log.tar.gz + +* os-nosdn-kvm-ha scenario can be executed from the jenkins project + "fuel-os-nosdn-kvm-ha-baremetal-daily-master" +* This scenario provides the High Availability feature by deploying + 3 controller,2 compute nodes and checking if all the 5 nodes + are accessible(IP,up & running). +* Test Scenario is passed if deployment is successful and all 5 nodes have + accessibility (IP , up & running). +* Observed that scenario is not running any testcase on top of deployment. + +Known Limitations, Issues and Workarounds +----------------------------------------- +.. Explain any known limitations here. + +* Test scenario os-nosdn-kvm-ha result is not stable. After node reboot + triggered by kvm plugin, sometimes puppet agent (mcollective) is not + responding with in the given time. + +References +---------- + +For more information on the OPNFV Danube release, please visit +http://www.opnfv.org/danube |
