[pve-devel] [PATCH ha-manager 13/15] test: ha tester: add test cases for loose colocation rules

Tue Mar 25 16:12:52 CET 2025
Add test cases for loose positive and negative colocation rules, i.e.
where services should be kept on the same node together or kept separate
nodes. These are copies of their strict counterpart tests, but verify
the behavior if the colocation rule cannot be met, i.e. not adhering to
the colocation rule. The test scenarios are:
- 2 neg. colocated services in a 3 node cluster; 1 node failing
- 2 neg. colocated services in a 3 node cluster; 1 node failing, but the
recovery node cannot start the service
- 2 pos. colocated services in a 3 node cluster; 1 node failing
- 3 pos. colocated services in a 3 node cluster; 1 node failing, but the
recovery node cannot start one of the services

+Test whether a loose negative colocation rule among two services makes one of

+failover of their previously assigned node.

+The test scenario is:
+- vm:101 and vm:102 should be kept separate
+- vm:101 and vm:102 are currently running on node2 and node3 respectively
+- node1 has a higher service count than node2 to test that the rule is applied

+Therefore, the expected outcome is:

+Test whether a loose positive colocation rule makes three services migrate to
+the same recovery node in case of a failover of their previously assigned node.
+If one of those fail to start on the recovery node (e.g. insufficient
+resources), the failed service will be relocated to another node.
+
+The test scenario is:
+- vm:101, vm:102, and fa:120002 should be kept together
+- vm:101, vm:102, and fa:120002 are all currently running on node3
+- fa:120002 will fail to start on node2
+- node1 has a higher service count than node2 to test that the rule is applied
+ even though it would be usually balanced between both remaining nodes
+
+Therefore, the expected outcome is:
+- As node3 fails, all services are migrated to node2
+- Two of those services will start successfully, but fa:120002 will be
+ relocated to another node, since it couldn't start on the same recovery node
