【 使用环境 】测试环境
【 使用版本 】
oceanbase/oceanbase-ce 4.1.0.0
【问题描述】清晰明确描述问题
用镜像部署oceanbase，挂载pv不生效，重启容器后数据丢失。
在pv
【复现路径】问题出现前后相关操作
mountPath配置/store 可以正常启动，日志里也能会打印 clog and data use the same disk (/store) 但实际并没有挂载成功，重启容器后数据丢失

就是想本地部署基于k8s的OB server, 但每次重启镜像实例数据盘就没了 ，配置了pv重启就报错了 如何解决 是配置不对吗

主要是想通过以下配置去挂载外部存储，然后启动就报错了

          volumeMounts:
            - name: oceanbase-pv
              mountPath: /root/ob
              subPath: ob
            - name: oceanbase-pv
              mountPath: /root/.obd
              subPath: obd
            - name: oceanbase-pv
              mountPath: /root/obagent
              subPath: obagent

报错日志已经上传在上面了

最新的加了以下配置就是上面那个图的结果，服务不知道是否启动成功，异常日志也不清楚如何查看了

 - name: oceanbase-pv
              mountPath: /root/obagent
              subPath: obagent

和上面发的错误日志文件里一样的错误码

在 K8s 里面的话推荐用 ob-operator 的方式来部署

这个镜像仅限于单机使用，直接 docker run 就行了，没必要把单机的放在 K8s 里去跑
