Description Surya Seetharaman 2021-08-30 13:37:36 UTC
Description of problem:


CNO only tolerates node.kubernetes.io/network-unavailable taint. In https://github.com/openshift/ovn-kubernetes/pull/671 we added the "k8s.ovn.org/network-unavailable" to block pod creations when ovnkube-node is down. We need to change the taint to be the official k8s one.

 - effect: NoSchedule
   key: node.kubernetes.io/network-unavailable
   operator: Exists

55s         Warning   FailedScheduling    pod/network-operator-5697868476-vlqnv    0/27 nodes are available: 1 node(s) didn't match Pod's node affinity/selector, 1 node(s) had taint {role: workload}, that the pod didn't tolerate, 25 node(s) had taint {k8s.ovn.org/network-unavailable: }, that the pod didn't tolerate.
