Version-Release number of selected component (if applicable): 3.5 How reproducible: Always Steps to Reproduce: 1. Upgrade OCP from 3.4 to 3.5. 2. Upgrade metrics stack using the ansible playbook using hostPath for cassandra PV. Actual results: The playbook keeps going but fails to update the hawkular-cassandra RC, the following error was found: STDERR: The ReplicationController "hawkular-cassandra-1" is invalid: * spec.template.spec.volumes[0].hostPath: Forbidden: may not specify more than 1 volume type * spec.template.spec.containers[0].volumeMounts[0].name: Not found: "cassandra-data" Expected results: The RC would be updated. Additional info: Workaround was found to change the RC definition to use emptyDir and after the upgrade finishes, modify it back to use hostPath.
