发表于 分类于

DELL 存储服务器的，CentOS 7版本挂载NFS出现的几个异常。

1、由于DELL 存储服务器，创建的目录是大写文件夹，在系统版本CentOS 7.5挂载正常，无论是挂载大写还是小写都是正常挂载，而在系统版本CentOS 7.9挂载出现以下错误
  • 本地操作错误

mount.nfs: mounting dfs01.xxx.xxx:/bms failed, reason given by server: No such file or directory

    yum install nfs-utils -y
    systemctl enable rpcbind
    systemctl restart rpcbind
3、权限问题，由于DELL 存储服务器设置文件权限设置不当导致

1、DELL 存储服务器设置允许根目录权限
2、DELL 存储服务器设置k8s pods里面的ip访问权限
3、DELL 存储服务器设置允许中文，否则挂载nfs里面创建文件提示File name too long
