Description of problem:
Converting IPv6 Primary Dual Stack to IPv6 Single stack causing control plane failures. OVN masters in CLBO state peridically OVN masters logs: http://shell.lab.bos.redhat.com/~anusaxen/convert/ MG is not working as cluster lands in bad shape. Happy to share cluster if needed for debugging
Version-Release number of selected component (if applicable):
4.13.0-0.nightly-2023-04-21-084440
How reproducible:
Always
Steps to Reproduce:
1.Bring cluster on IPv6 Primary Dual Stack 2.Edit network.config.openshift.io from dual stack to single like as follow spec: clusterNetwork: - cidr: fd01::/48 hostPrefix: 64 - cidr: 10.128.0.0/14 hostPrefix: 23 externalIP: policy: {} networkType: OVNKubernetes serviceNetwork: - fd02::/112 - 172.30.0.0/16 status: clusterNetwork: - cidr: fd01::/48 hostPrefix: 64 - cidr: 10.128.0.0/14 hostPrefix: 23 clusterNetworkMTU: 1400 networkType: OVNKubernetes serviceNetwork: - fd02::/112 - 172.30.0.0/16 TO apiVersion: v1 items: - apiVersion: config.openshift.io/v1 kind: Network metadata: creationTimestamp: "2023-04-27T14:11:37Z" generation: 3 name: cluster resourceVersion: "81045" uid: 28f15675-e739-4262-9acc-4c2c0df4b38d spec: clusterNetwork: - cidr: fd01::/48 hostPrefix: 64 externalIP: policy: {} networkType: OVNKubernetes serviceNetwork: - fd02::/112 status: clusterNetwork: - cidr: fd01::/48 hostPrefix: 64 clusterNetworkMTU: 1400 networkType: OVNKubernetes serviceNetwork: - fd02::/112 kind: List metadata: resourceVersion: "" 3. Wait for control plane components to roll out successfully
Actual results:
Cluster fails with network, ETCD, Kube API and ingress failures
Expected results:
Cluster should convert to IPv6 single without any issues
Additional info:
MGs not working due to varios control place restricting it
