Description of problem: As noticed by Ladislav: On particular role compositions, the code joining the update_tasks might order things differently then on a typical 3ctrl control plane and the ovn-dbs tasks at step1 (which require the cluster to be up) will happen after the pacemaker task at step1 which stops the cluster. So we can observe something like the following: 2021-09-10 10:05:13.370339 | 001c2891-506d-f833-ff5a-000000000954 | TASK | Change the bundle operation timeout 2021-09-10 10:05:14.136798 | 001c2891-506d-f833-ff5a-000000000954 | CHANGED | Change the bundle operation timeout | ovn-db-01 2021-09-10 10:05:14.137982 | 001c2891-506d-f833-ff5a-000000000954 | TIMING | Change the bundle operation timeout | ovn-db-01 | 0:00:54.808754 | 0.77s 2021-09-10 10:05:14.146853 | 001c2891-506d-f833-ff5a-000000000956 | TASK | Acquire the cluster shutdown lock to stop pacemaker cluster 2021-09-10 10:05:14.508085 | 001c2891-506d-f833-ff5a-000000000956 | CHANGED | Acquire the cluster shutdown lock to stop pacemaker cluster | ovn-db-01 2021-09-10 10:05:14.509257 | 001c2891-506d-f833-ff5a-000000000956 | TIMING | Acquire the cluster shutdown lock to stop pacemaker cluster | ovn-db-01 | 0:00:55.180032 | 0.36s 2021-09-10 10:05:14.518668 | 001c2891-506d-f833-ff5a-000000000957 | TASK | Stop pacemaker cluster 2021-09-10 10:05:18.559627 | 001c2891-506d-f833-ff5a-000000000957 | CHANGED | Stop pacemaker cluster | ovn-db-01 2021-09-10 10:05:18.560561 | 001c2891-506d-f833-ff5a-000000000957 | TIMING | Stop pacemaker cluster | ovn-db-01 | 0:00:59.231336 | 4.04s 2021-09-10 10:05:18.569161 | 001c2891-506d-f833-ff5a-000000000958 | TASK | Start pacemaker cluster 2021-09-10 10:05:18.627924 | 001c2891-506d-f833-ff5a-000000000958 | SKIPPED | Start pacemaker cluster | ovn-db-01 2021-09-10 10:05:18.628678 | 001c2891-506d-f833-ff5a-000000000958 | TIMING | Start pacemaker cluster | ovn-db-01 | 0:00:59.299453 | 0.06s 2021-09-10 10:05:18.637292 | 001c2891-506d-f833-ff5a-000000000959 | TASK | Release the cluster shutdown lock 2021-09-10 10:05:18.694945 | 001c2891-506d-f833-ff5a-000000000959 | SKIPPED | Release the cluster shutdown lock | ovn-db-01 2021-09-10 10:05:18.695717 | 001c2891-506d-f833-ff5a-000000000959 | TIMING | Release the cluster shutdown lock | ovn-db-01 | 0:00:59.366493 | 0.06s 2021-09-10 10:05:18.704368 | 001c2891-506d-f833-ff5a-00000000095a | TASK | Clear ovndb cluster pacemaker error 2021-09-10 10:05:19.368816 | 001c2891-506d-f833-ff5a-00000000095a | FATAL | Clear ovndb cluster pacemaker error | ovn-db-01 | error={"changed": true, "cmd": "pcs resource cleanup ovn-dbs-bundle", "delta": "0:00:00.399084", "end": "2021-09-10 10:05:20 .044985", "msg": "non-zero return code", "rc": 1, "start": "2021-09-10 10:05:19.645901", "stderr": "Error: Unable to forget failed operations of resource: ovn-dbs-bundle\nError connecting to the CIB manager: Transport endpoint is not connected\nError perf orming operation: Transport endpoint is not connected", "stderr_lines": ["Error: Unable to forget failed operations of resource: ovn-dbs-bundle", "Error connecting to the CIB manager: Transport endpoint is not connected", "Error performing operation: Tran sport endpoint is not connected"], "stdout": "", "stdout_lines": []} We cannot call pcs resource cleanup at step1, we must call it at step0 so we're guaranteed that the cluster is up, no matter how heat/ansible decide to order the update_tasks.
