Change Details

I just did these upgrades in codfw1dev and things went very smoothly. Steps: [] Merge an install_server patch moving these hosts to Buster [] Determine which host is active and which is standby: ``` root@cloudcontrol1003:~# neutron l3-agent-list-hosting-router d93771ba-2711-4f88-804a-8df6fd03978a ``` [] Re-image standby host, confirm puppet stability, reboot [] Confirm (with above command) that the standby node is up and running [] Fail-over by stopping the l3-agent on the active host ``` service neutron-l3-agent stop ``` [] Confirm networking still working, confirm that active/standby hosts have traded places [] Re-image remaining host
