After updating the MOSK managed cluster, admission controller prohibits the OsDpl update with the following error message:

TungstenFabric as network backend and setting of floating network
physnet name without network type and segmentation id are not compatible.

As a workaround, after the update remove the orphaned physnet parameter from the OsDpl CR:

features:
  neutron:
    backend: tungstenfabric
    floating_network:
      enabled: true
      physnet: physnet1

As a workaround, restart the rook-ceph-operator pod:

kubectl -n rook-ceph scale deploy rook-ceph-operator --replicas 0
kubectl -n rook-ceph scale deploy rook-ceph-operator --replicas 1
