             Summary: Existing PVC can slip into as the storage for operator
                 Key: WFWIP-255
                 URL: https://issues.jboss.org/browse/WFWIP-255
             Project: WildFly WIP
          Issue Type: Bug
          Components: OpenShift
            Reporter: Petr Kremensky
            Assignee: Jeff Mesnil


PVC created manually (any accessModes) by user can be slip into the Operator.

*Things to notice here:*
 * WFWIP-186 StorageSpec is intended to be mounted in ReadWriteOnce mode
 * {{foo: bar}} should never pass the validation as it is not a valid storage configuration

*reproduce*
* create PVC, use the ${APP_NAME}-volume-quickstart-0 name - the PVC would be in normal circumstances created by the operator
