Ubuntu(Linux) mount error(22):解决办法

错误log

执行命令

sudo mount -t cifs //ip/sharename /tmp/1 -o username=11,password=tmp

错误提示

mount error(22): Invalid argument Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)

解决办法

查看root cause:

tail -f /var/log/kern.log

提示：

No dialect specified on mount. Default has changed to a more secure dialect, SMB2.1 or later (e.g. SMB3), from CIFS (SMB1). To use the less secure SMB1 dialect to access old servers which do not support SMB3 (or SMB2.1) specify vers=1.0 on mount.

提示里面已经指明解决方法，没有指定cifs共享的版本，cifs分为smb1.0/2.0/3.0/3.1。

解决办法

sudo mount -t cifs //ip/sharename /tmp/1 -o username=11,password=tmm,vers=1.0
