Cannot create an external Ceph storage system in Red Hat OpenShift Data Foundation when using OVNKubernetes

Solution Verified - Updated -


After installing the Red Hat OpenShift Data Foundation (ODF) Operator on a Red Hat OpenShift Container Platform cluster, we cannot create a storage system that utilizes an external Ceph cluster.

We are using a second network interface on the cluster nodes for storage traffic. This interface is on a separate network from the pod network and is configured using the NMState operator.

This occurs when using the OVNKubernetes network stack. The problem does not exist when using the OpenShiftSDN network stack.


  • Red Hat OpenShift Container Platform 4.x
  • OVNKubernetes networking
  • A second interface on the cluster nodes, used for storage traffic.
