helm版本

Client: &version.Version{SemVer:"v2.14.3", GitCommit:"0e7f3b6637f7af8fcfddb3d2941fcc7cbebb0085", GitTreeState:"clean"} Server: &version.Version{SemVer:"v2.14.3", GitCommit:"0e7f3b6637f7af8fcfddb3d2941fcc7cbebb0085", GitTreeState:"clean"}

起初一直以为是服务本身问题，也曾怀疑过是阿里的文件存储有访问策略，手动在三台节点上mount挂载，挂载成功，没有报错

检查conf/common.yaml发现将nfs_path: /nfs 项目误配置成 nfs_path: true，修改后执行uninstall.sh卸载，再执行install.sh重新安装后成功跳过

紧接着又重复出现了昨天的报错：minio启动报错

用kubectl get pods –all-namespaces 查看pods运行情况，发现nfs-client-nfs-client-provisioner-685f7fdf45-4xbzj这个pod启动失败

用kubectl describe pod nfs-client-nfs-client-provisioner-685f7fdf45-4xbzj -n kube-system查看发现是nfs
nfs挂载失败导致的，失败命令：mount -t nfs …. ***.aliyun.com:/nfs

最初报错信息如下：

helm版本

检查conf/common.yaml发现将nfs_path: /nfs 项目误配置成 nfs_path: true，修改后执行uninstall.sh卸载，再执行install.sh重新安装后成功跳过

问题来了，检查阿里的文件存储服务发现路径是 / ，/nfs是我自己挂载到服务器目录，而common.yaml里nfs_path: 的配置项是要求填写nfs服务端的路径，所以，在common.yaml里改成nfs_path: /，再次执行install.sh集群安装成功！

总结本次部署失败原因在于错误理解了nfs_path配置项的含义，希望后面的小伙伴以此为戒，检查好nfs路径。
