Description Carlos Goncalves 2020-02-01 17:40:34 UTC 
Provisioning of overcloud failed while executing the Octavia Ansible playbook. Seen in downstream CI, not 100% reproducible: 1 build failed, 3 other builds passed with the same compose.

Comment 2 Brent Eagles 2020-02-05 16:21:15 UTC 
The cause is that an operation fails for one of the controllers in a role that is run earlier, octava-controller-config:

2020-02-01 12:01:13,689 p=226016 u=root |  fatal: [controller-2]: FAILED! => {"changed": false, "cmd": "set -o pipefail\nport_id=\"$(openstack port show octavia-health-manager-controller-2.      redhat.local-listen-port -f value -c id 2> /dev/null)\"\nif [[ -z \"${port_id}\" ]]; then\n  neutron port-create lb-mgmt-net --binding:host_id=controller-2.redhat.                                local                                             --no-security-groups                                             --port-security-enabled=False                                             --    device-owner Octavia:health-mgr                                             --name octavia-health-manager-controller-2.redhat.local-listen-port                                             -f     value                                             -c id\nfi", "delta": "0:00:07.065055", "end": "2020-02-01 12:01:13.649635", "msg": "non-zero return code", "rc": 1, "start": "2020-02-01 12:01:  06.584580", "stderr": "neutron CLI is deprecated and will be removed in the future.

This results in o-hm-ip not being set for that node and why it cannot be referenced later. There are probably several issues here:

- Why the internal error in neutron for one of the nodes and not the others?
- Why did the ansible continue? Is that by design?
- If yes to above, we need to make Octavia deployment more resilient to apparently transient errors. Even so, completely failure to configure resources (i.e. unable to achieve a working overcloud) should fail the deploy.
Comment 6 Carlos Goncalves 2020-03-28 15:12:29 UTC 
Reopening as we are seeing this again in downstream CI. Neutron is raising MechanismDriverError and returning HTTP 500 to user on port create.
