There one file can be edit by more than one user, if one user open this file and recevie the information : other user had opened this file now ,you only can open this file for read only.

Question:

You will want to look at the command "smbstatus". That will tell you what files are locked and by who.

Thank you very much!
Is there any way to close special connection but not by close cifs services or tell users to quit program.
i do this just for unlocked some file.
because some times,user had shutdowned his computer,but freenas still locked the file .

You could kill the process that the user is on with "kill -9 pid"

If you want to close only the file, you can connect to the freenas server via compmgmt.msc on a windows computer, view open files, and close the offending one. If you're in an ad environment it will require being domain admin. In a workgroup you will need to grant some rights to your user. I believe it requires sediskoperatorprivilege (net rpc rights grant [user] SeDiskOperatorPrivilege). Full list of rights can be viewed here: https://www.samba.org/samba/docs/man/Samba-HOWTO-Collection/rights.html
