    • It's a known issue that IPv6 OVN load balancers fail to create health monitors in OSP 17.1 <link-to-bug>.
    • Known Issue
    • In Progress

      Below two tests:

      "[sig-installer][Suite:openshift/openstack][lb][Serial] The Openstack platform should apply lb-method on TCP OVN LoadBalancer when a TCP svc with monitors and ETP:Local is created on Openshift"
      "[sig-installer][Suite:openshift/openstack][lb][Serial] The Openstack platform should apply lb-method on UDP OVN LoadBalancer when a UDP svc with monitors and ETP:Local is created on Openshift"
      

      fail running on an ipv6primary dualstack cluster with below cloud-provider-config applied in the cluster running on top of RHOSP17.1:

      $ oc get cm -n openshift-config cloud-provider-config  -o json | jq -r .data.config 
      [Global]
      secret-name = openstack-credentials
      secret-namespace = kube-system
      region = regionOne
      ca-file = /etc/kubernetes/static-pod-resources/configmaps/cloud-config/ca-bundle.pem
      
      [LoadBalancer]
      floating-network-id = 663be8b6-09db-4be4-bb33-7fc87c0ec51a
      lb-provider = ovn
      lb-method = SOURCE_IP_PORT
      subnet-id = e8399103-9dac-44ae-a2bf-862800d73412
      create-monitor = False
      monitor-delay = 10s
      monitor-timeout = 10s
      monitor-max-retries = 1
      max-shared-lb = 2
      

      The test shows that the 6 OCP nodes are members in ONLINE status, instead of two, which is the expectation when monitors are enabled (the test creates a service with 2 endpoints):
