| Lukas Bezdicka | 2023-08-10 13:15:25 UTC | Doc Text | Cause: There is race in deployment steps for ovn_controller and ovn_dbs which causes ovn_dbs to be upgraded before ovn_controller. Consequence: If ovn_controller is not upgraded before ovn_dbs it will throw error before being restarted to the new version causing packet loss. Workaround (if any): Result: Estimated 1min network outage if the race is hit during OVN upgrade. | |

| Jenny-Anne Lynch | 2023-08-10 15:24:59 UTC | Doc Text | Cause: There is race in deployment steps for ovn_controller and ovn_dbs which causes ovn_dbs to be upgraded before ovn_controller. Consequence: If ovn_controller is not upgraded before ovn_dbs it will throw error before being restarted to the new version causing packet loss. Workaround (if any): Result: Estimated 1min network outage if the race is hit during OVN upgrade. | There is currently a known issue with a race condition in the deployment steps for `ovn_controller` and `ovn_dbs`, which causes `ovn_dbs` to be upgraded before `ovn_controller`. If `ovn_controller` is not upgraded before `ovn_dbs`, an error before the restart to the new version causes packet loss. There is an estimated one-minute network outage if the race condition occurs during the Open Virtual Network (OVN) upgrade. A fix is expected in a later RHOSP release. |
