很奇怪，我不知道它从哪里来的10.100.155.82？这是ClusterIP的先前IP（与nfs服务有关）...

            #server: 10.11.250.37

此超时/使用错误IP可能是什么原因？

我尝试删除部署，更改了似乎仍然不起作用的名称，但几分钟后它起作用了……真的很奇怪吗？

再次遇到此问题...：

它一直在使用旧的NFS IP。这是一个错误...：

Mounting arguments: --description=Kubernetes transient mount for /var/lib/kubelet/pods/9470ac17-a8b9-11e9-bdf7-38ffa66115bc/volumes/kubernetes.io~nfs/nfs-data-src --scope -- mount -t nfs 10.11.250.37:/exports/www/typo3_src /var/lib/kubelet/pods/9470ac17-a8b9-11e9-bdf7-38ffa66115bc/volumes/kubernetes.io~nfs/nfs-data-src
Output: Running scope as unit: run-ref2095cb52c94d0c87de5458c3b16733.scope
mount.nfs: Connection timed out

NFS卷安装在IP地址不正确的Kubernetes上超时吗？
