mount error(5): Input/output error

试图从Linux挂载windows的共享文件时：

mount.cifs //192.168.216.27/ova ova_tmp/ -o user=xxx,pass=xxx

出现了如下错误：

mount error(5): Input/output error
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)

解决办法是加上sec=ntlm选项

mount.cifs //192.168.216.27/ova ova_tmp/ -o user=xxx,pass=xxx,sec=ntlm

秒挂啦！
