Yardstick Test Case Description TC057
*************************************
+-----------------------------------------------------------------------------+
|OpenStack Controller Cluster Management Service High Availability |
+==============+==============================================================+
|test case id | |
+--------------+--------------------------------------------------------------+
|test purpose | This test case will verify the quorum configuration of the |
| | cluster manager(pacemaker) on controller nodes. When a |
| | controller node , which holds all active application |
| | resources, failed to communicate with other cluster nodes |
| | (via corosync), the test case will check whether the standby |
| | application resources will take place of those active |
| | application resources which should be regarded to be down in |
| | the cluster manager. |
+--------------+--------------------------------------------------------------+
|test method | This test case kills the processes of cluster messaging |
| | service(corosync) on a selected controller node(the node |
| | holds the active application resources), then checks whether |
| | active application resources are switched to other |
| | controller nodes and whether the Openstack commands are OK. |
+--------------+--------------------------------------------------------------+
|attackers | In this test case, an attacker called "kill-process" is |
| | needed. This attacker includes three parameters: |
| | 1) fault_type: which is used for finding the attacker's |
| | scripts. It should be always set to "kill-process" in this |
| | test case. |
| | 2) process_name: which is the process name of the load |
| | balance service. If there are multiple processes use the |
| | same name on the host, all of them are killed by this |
| | attacker. |
| | 3) host: which is the name of a control node being attacked. |
| | |
| | In this case, this process name should set to "corosync" , |
| | for example |
| | -fault_type: "kill-process" |
| | -process_name: "corosync" |
| | -host: node1 |
+--------------+--------------------------------------------------------------+
|monitors | In this test case, a kind of monitor is needed: |
| | 1. the "openstack-cmd" monitor constantly request a specific |
| | Openstack command, which needs two parameters: |
| | 1) monitor_type: which is used for finding the monitor class |
| | and related scripts. It should be always set to |
| | "openstack-cmd" for this monitor. |
| | 2) command_name: which is the command name used for request |
| | |
| | In this case, the command_name of monitor1 should be services|
| | that are managed by the cluster manager. (Since rabbitmq and |
| | haproxy are managed by pacemaker, most Openstack Services |
| | can be used to check high availability in this case) |
| | |
| | (e.g.) |
| | monitor1: |
| | -monitor_type: "openstack-cmd" |
| | -command_name: "nova image-list" |
| | monitor2: |
| | -monitor_type: "openstack-cmd" |
| | -command_name: "neutron router-list" |
| | monitor3: |
| | -monitor_type: "openstack-cmd" |
| | -command_name: "heat stack-list" |
| | monitor4: |
| | -monitor_type: "openstack-cmd" |
| | -command_name: "cinder list" |
| | |
+--------------+--------------------------------------------------------------+
|checkers | In this test case, a checker is needed, the checker will |
| | the status of application resources in pacemaker and the |
| | checker have three parameters: |
| | 1) checker_type: which is used for finding the result |
| | checker class and related scripts. In this case the checker |
| | type will be "pacemaker-check-resource" |
| | 2) resource_name: the application resource name |
| | 3) resource_status: the expected status of the resource |
| | 4) expectedValue: the expected value for the output of the |
| | checker script, in the case the expected value will be the |
| | identifier in the cluster manager |
| | 3) condition: whether the expected value is in the output of |
| | checker script or is totally same with the output. |
| | (note: pcs is required to installed on controller node in |
| | order to run this checker) |
| | |
| | (e.g.) |
| | checker1: |
| | -checker_type: "pacemaker-check-resource" |
| | -resource_name: "p_rabbitmq-server" |
| | -resource_status: "Stopped" |
| | -expectedValue: "node-1" |
| | -condition: "in" |
| | checker2: |
| | -checker_type: "pacemaker-check-resource" |
| | -resource_name: "p_rabbitmq-server" |
| | -resource_status: "Master" |
| | -expectedValue: "node-2" |
| | -condition: "in" |
+--------------+--------------------------------------------------------------+
|metrics | In this test case, there are two metrics: |
| | 1)service_outage_time: which indicates the maximum outage |
| | time (seconds) of the specified Openstack command request. |
+--------------+--------------------------------------------------------------+
|test tool | None. Self-developed. |
+--------------+--------------------------------------------------------------+
|references | ETSI NFV REL001 |
+--------------+--------------------------------------------------------------+
|configuration | This test case needs two configuration files: |
| | 1) test case file: opnfv_yardstick_tc057.yaml |
| | -Attackers: see above "attackers" description |
| | -Monitors: see above "monitors" description |
| | -Checkers: see above "checkers" description |
| | -Steps: the test case execution step, see "test sequence" |
| | description below |
| | |
| | 2)POD file: pod.yaml |
| | The POD configuration should record on pod.yaml first. |
| | the "host" item in this test case will use the node name in |
| | the pod.yaml. |
+--------------+------+----------------------------------+--------------------+
|test sequence | description and expected result |
| | |
+--------------+--------------------------------------------------------------+
|step 1 | start monitors: |
| | each monitor will run with independently process |
| | |
| | Result: The monitor info will be collected. |
| | |
+--------------+--------------------------------------------------------------+
|step 2 | do attacker: connect the host through SSH, and then execute |
| | the kill process script with param value specified by |
| | "process_name" |
| | |
| | Result: Process will be killed. |
| | |
+--------------+--------------------------------------------------------------+
|step 3 | do checker: check whether the status of application |
| | resources on different nodes are updated |
| | |
+--------------+--------------------------------------------------------------+
|step 4 | stop monitors after a period of time specified by |
| | "waiting_time" |
| | |
| | Result: The monitor info will be aggregated. |
| | |
+--------------+--------------------------------------------------------------+
|step 5 | verify the SLA |
| | |
| | Result: The test case is passed or not. |
| | |
+--------------+------+----------------------------------+--------------------+
|post-action | It is the action when the test cases exist. It will check |
| | the status of the cluster messaging process(corosync) on the |
| | host, and restart the process if it is not running for next |
| | test cases. |
| | Notice: This post-action uses 'lsb_release' command to check |
| | the host linux distribution and determine the OpenStack |
| | service name to restart the process. Lack of 'lsb_release' |
| | on the host may cause failure to restart the process. |
| | |
+--------------+------+----------------------------------+--------------------+
|test verdict | Fails only if SLA is not passed, or if there is a test case |
| | execution problem. |
| | |
