Public bug reported: The request to create a load balancer is erroring out because there are no available IPs in the network pool that it is using. However, OVN provider driver is not handling this error correctly and ends up throwing a 500 error response, when it should just be relaying the 409 that neutron threw above.
This masks the issue and let’s the user think that the service is misbehaving while in fact, they need to go back and free up some IP addresses. 2025-06-15 11:41:44,382.382 1 ERROR octavia.api.drivers.utils [None req-62861c3a-b121-4a6e-bebf-5bdebab8c92f -
