Openshift -超时过期，等待卷附加或挂载到pod

Question

我在部署Openshift模板时遇到了一些困难，特别是在附加持久卷方面。该模板用于部署Jira和MYSQL数据库以实现持久性。我已经部署了以下持久性卷配置：

apiVersion: v1
kind: PersistentVolume
metadata:
  name: mysqlpv0003 
spec:
  capacity:
    storage: 2Gi 
  accessModes:
  - ReadWriteMany
  nfs: 
    path: /var/nfs/mysql
    server: 192.168.0.171
  persistentVolumeReclaimPolicy: Retain 

其中，192.168.0.171是有效的、正在工作的nfs服务器。我的目标是使用这个持久卷作为MYSQL服务器的存储空间。我试图部署的模板如下：

运行时，MYSQL服务器的部署最终失败，出现以下错误：

无法为pod挂载卷"database-1-qvv86_test3(54f01c55-6885-11e9-bc42-3a342852673a)"：超时过期，等待卷附加或挂载为pod“test3”/“数据库-1-qv86”。未挂载卷列表=数据库-数据默认值-令牌-8 8hjgv。未附加卷列表=数据库-数据默认值-令牌-8 8hjgv

持久卷声明成功地附加到持久卷，但据我所知，荚没有附加到该卷。模板被部署在一个新项目中，PV是新创建的，nfs是空的。我看不出pod如何引用持久卷声明时有任何错误。我不知道为什么会出现这个错误，但我只是在学习模板，显然缺少了一些东西。有人看到我错过了什么吗？

问题在于我的NFS权限。以下是my /etc/exports文件的工作内容：

/var/nfs        *(rw,root_squash,no_wdelay)
