2. 解决

# https://github.com/kubernetes-sigs/nfs-subdir-external-provisioner/issues/25

# 解决：
# 修改apiserver的yaml文件
$ vim /etc/kubernetes/manifests/kube-apiserver.yaml
spec:
  containers:
  - command:
    - kube-apiserver
    - --feature-gates=RemoveSelfLink=false
    
# 执行apiserver文件（twice）
$ kubectl apply -f /etc/kubernetes/manifests/kube-apiserver.yaml
$ kubectl apply -f /etc/kubernetes/manifests/kube-apiserver.yaml

3. 查看pvc、pods

# 恢复正常

# pvc
$ kubectl get pvc

# pods
