Samba挂载报错mount error(22): Invalid argument

Samba挂载采用cifs方式报错：mount error(22): Invalid argument Refer to the mount.cifs(8) manual page (e.g. man mount.cifs) 查看系统日志： 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. 没有指定cifs共享的版本，cifs分为smb1.0/2.0/3.0/3.1 mount -t cifs //ip/data /test -o username=test,password=test,vers=3.0 sec参数设置也可能导致类似报错，可通过man查看选择sec参数设置为那一项
