+Yardstick Test Case Description TC052
+*************************************
+
++-----------------------------------------------------------------------------+
+|OpenStack Controller Node Disk I/O Block High Availability |
+| |
++--------------+--------------------------------------------------------------+
+|test case id | OPNFV_YARDSTICK_TC052: OpenStack Controller Node Disk I/O |
+| | Block High Availability |
++--------------+--------------------------------------------------------------+
+|test purpose | This test case will verify the high availability of control |
+| | node. When the disk I/O of a specified disk is blocked, |
+| | which breaks down the Openstack services on this node. Read |
+| | and write services should still be accessed by other |
+| | controller nodes, and the services on failed controller node |
+| | should be isolated. |
++--------------+--------------------------------------------------------------+
+|test method | This test case blocks the disk I/O of a specified control |
+| | node, then checks whether the services that need to read or |
+| | wirte the disk of the control node are OK with some monitor |
+| | tools. |
++--------------+--------------------------------------------------------------+
+|attackers | In this test case, an attacker called "disk-block" is |
+| | needed. This attacker includes two parameters: |
+| | 1) fault_type: which is used for finding the attacker's |
+| | scripts. It should be always set to "disk-block" in this |
+| | test case. |
+| | 2) host: which is the name of a control node being attacked. |
+| | e.g. |
+| | -fault_type: "disk-block" |
+| | -host: node1 |
++--------------+--------------------------------------------------------------+
+|monitors | In this test case, two kinds of monitor are 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. |
+| | |
+| | e.g. |
+| | -monitor_type: "openstack-cmd" |
+| | -command_name: "nova flavor-list" |
+| | |
+| | 2. the second monitor verifies the read and write function |
+| | by a "operation" and a "result checker". |
+| | the "operation" have two parameters: |
+| | 1) operation_type: which is used for finding the operation |
+| | class and related scripts. |
+| | 2) action_parameter: parameters for the operation. |
+| | the "result checker" have three parameters: |
+| | 1) checker_type: which is used for finding the reuslt |
+| | checker class and realted scripts. |
+| | 2) expectedValue: the expected value for the output of the |
+| | checker script. |
+| | 3) condition: whether the expected value is in the output of |
+| | checker script or is totally same with the output. |
+| | |
+| | In this case, the "operation" adds a flavor and the "result |
+| | checker" checks whether ths flavor is created. Their |
+| | parameters show as follows: |
+| | operation: |
+| | -operation_type: "nova-create-flavor" |
+| | -action_parameter: |
+| | flavorconfig: "test-001 test-001 100 1 1" |
+| | result checker: |
+| | -checker_type: "check-flavor" |
+| | -expectedValue: "test-001" |
+| | -condition: "in" |
++--------------+--------------------------------------------------------------+
+|metrics | In this test case, there is one metric: |
+| | 1)service_outage_time: which indicates the maximum outage |
+| | time (seconds) of the specified Openstack command request. |
++--------------+--------------------------------------------------------------+
+|test tool | Developed by the project. Please see folder: |
+| | "yardstick/benchmark/scenarios/availability/ha_tools" |
+| | |
++--------------+--------------------------------------------------------------+
+|references | ETSI NFV REL001 |
+| | |
++--------------+--------------------------------------------------------------+
+|configuration | This test case needs two configuration files: |
+| | 1) test case file: opnfv_yardstick_tc052.yaml |
+| | -Attackers: see above "attackers" discription |
+| | -waiting_time: which is the time (seconds) from the process |
+| | being killed to stoping monitors the monitors |
+| | -Monitors: see above "monitors" discription |
+| | -SLA: see above "metrics" discription |
+| | |
+| | 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 | do attacker: connect the host through SSH, and then execute |
+| | the block disk I/O script on the host. |
+| | |
+| | Result: The disk I/O of the host will be blocked |
+| | |
++--------------+--------------------------------------------------------------+
+|step 2 | start monitors: |
+| | each monitor will run with independently process |
+| | |
+| | Result: The monitor info will be collected. |
+| | |
++--------------+--------------------------------------------------------------+
+|step 3 | do operation: add a flavor |
+| | |
++--------------+--------------------------------------------------------------+
+|step 4 | do result checker: check whether the falvor is created |
+| | |
++--------------+--------------------------------------------------------------+
+|step 5 | stop monitors after a period of time specified by |
+| | "waiting_time" |
+| | |
+| | Result: The monitor info will be aggregated. |
+| | |
++--------------+--------------------------------------------------------------+
+|step 6 | verify the SLA |
+| | |
+| | Result: The test case is passed or not. |
+| | |
++--------------+--------------------------------------------------------------+
+|post-action | It is the action when the test cases exist. It excutes the |
+| | release disk I/O script to release the blocked I/O. |
++--------------+--------------------------------------------------------------+
+|test verdict | Fails if monnitor SLA is not passed or the result checker is |
+| | not passed, or if there is a test case execution problem. |
+| | |
