持续音量和打开移位3.11

我刚刚安装了openshift okd 3.11,正在尝试一个持久的postgres数据库。

尝试创建数据库后,我得到以下错误:

MountVolume.SetUp failed for volume "postgresql" : 
mount failed: exit status 32 Mounting command: systemd-run Mounting arguments: --description=Kubernetes transient mount for /var/lib/origin/openshift.local.volumes/pods/b76a314a-d59a-11e8-a502-6c626d58b24d/volumes/kubernetes.io~nfs/postgresql --scope -- mount -t nfs apps.mydomain.com:/pg-data /var/lib/origin/openshift.local.volumes/pods/b76a314a-d59a-11e8-a502-6c626d58b24d/volumes/kubernetes.io~nfs/postgresql Output: 
Running scope as unit run-7329.scope. mount.nfs: Protocol not supported

我还创建了以下持久卷:

apiVersion: v1
kind: PersistentVolume
metadata:
  name: postgresql 
spec:
  capacity:
    storage: 5Gi 
  accessModes:
  - ReadWriteOnce 
  nfs: 
    path: /pg-data 
    server: apps.mydomain.com 
  persistentVolumeReclaimPolicy: Retain

即使在创建pv(使用 oc create -f pv.yml )我仍然得到上面的错误。
