【Linux】mount挂载问题案例

老许家的小长工2025-06-24 16:18

记录一次挂载问题,服务端共享路径已经显示出来，但客户端挂载就报下面的错误。

bash 复制代码

mount: wrong fs type, bad option, bad superblock on 172.16.11.11:/opt/file/yami-saas,
       missing codepage or helper program, or other error
       (for several filesystems (e.g. nfs, cifs) you might
       need a /sbin/mount.<type> helper program)

       In some cases useful info is found in syslog - try
       dmesg | tail or so.

查看dmesg日志

bash 复制代码

[root@5gprd-0002 opt]# dmesg | tail

问题原因是在服务器上没有安装nfs。

客户端安装yum -y install nfs-utils,问题解决，恢复正常挂载。
