elasticsearch初始容器更改所有权失败，原因是在kubernetes部署中pod启动失败

Question

我正在kubernetes中部署elasticsearch（v1.15.2，我正在艰难地部署k8s），遵循此doc，现在启动pod失败并抛出此错误：

Back-off restarting failed container

我在kubernetes仪表板中发现初始化容器启动失败：

并使用此命令检查初始容器的日志：

kubectl logs quickstart-es-default-0 -c elastic-internal-init-filesystem

这是日志输出：

$ kubectl logs quickstart-es-default-0 -c elastic-internal-init-filesystem

我已经在互联网上搜索并找到this question。并不能解决我的问题。现在我使用的是由ElasticSearch加载的PV作为NFS文件夹，该文件夹是root用户影响ES吗？这是我的PV文件夹：

[root@ops001 es]# pwd
/opt/data/data/es
[root@ops001 es]# ll
total 8
drwxrwxrwx 2 root root 4096 Feb 27 10:57 pv1
drwxrwxrwx 2 root root 4096 Feb 27 13:59 pv2(Elastic using now)

如何解决此问题？
