我在部署Openshift模板时遇到一些困难，特别是在附加永久卷方面。该模板旨在部署Jira和MYSQL数据库以实现持久性。我已部署以下持久卷配置：
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
192.168.0.171是有效的nfs服务器。我的目标是使用此持久卷作为MYSQL服务器的存储。我尝试部署的模板如下：
---

运行时，MYSQL服务器的部署最终失败，并显示以下错误：
无法挂载Pod的卷 “数据库-1-qvv86_test3（54f01c55-6885-11e9-bc42-3a342852673a）”： 超时已到期，等待卷连接或挂载到Pod “ test3” /“ database-1-qvv86”。未装入的卷列表= [数据库数据 default-token-8hjgv]。未连接卷的列表= [数据库数据 default-token-8hjgv]
永久卷声明已成功附加到永久卷，但据我所知，吊舱未附加到该卷。该模板正在一个新项目中部署，并且PV已重新创建，并且nfs为空。我看不到Pod如何引用持久卷声明的任何错误。我不确定为什么会发生此错误，但是我只是在学习模板，并且显然缺少一些东西。有人看到我所缺少的吗？
答案 0 :(得分：1)
问题出在我的NFS权限中。这是我的/ etc / exports文件的工作内容：
/var/nfs *(rw,root_squash,no_wdelay)
