| [XP Pro] fsmgmt.msc - perform tasks in commandline
hi guys i am new here but hope you can help me out.
I am trying to perform a task of breaking file locks hosted on an NFS file store. This has been a manual task for us. every time we need to deploy files.
we execute fsmgmt.msc map to a server, go to open files, select the files we need to close and close them.
What we are trying to do is to automate this process, I was wondering if this is possible to do in commandline.

| 1. You can execute this from a command line on the server:
for /f "skip=4 tokens=1" %g in ('net files') do net files %g /close
2. Using Microsoft/Sysinternals PsExec you could use a command line remotely; (or put the string in a "LockUndo.CMD" batch file and execute it remotely for each server):
===========
Rem LockUndo.CMD
Rem Example with two example servernames: test1 & test2
Rem Untested; there may be a syntax error. Concept piece only.
for %%h in (
"test1"
"test2"
) do (
psexec -accepteula -e "\\%%~h" "cmd /c for /f "skip=4 tokens=1" %%g in ('net files') do net files %%g /close"
)
exit
Or something similar to this concept. This closes all locks on all files on the servers in the list.

| I do not understand the problem you are raising with what I wrote.
net files /close will clear any of the four oploc types on files if the snap-in fsmgmt.msc will.
If you are thinking this is not really NFS but CIFS, you are likely right; but if the snap-in works, so will net file. (It could even be both). |

| I was replying to the OP.
As far as I understand it, the snapin (and net file) will close the instance of the file that is open via CIFS, and not any other way.
So if remote cifs user has the file open as 'id 1' and a remote nfs user is accessing the same file(**) and a third local-to-server app has the same file open as well, then 'net file 1 /close' will close the cifs user's open file handle, but will do nothing for the remote nfs user's access and nothing for the local access.
All this is fine for cifs file servers (i.e. normal MS Windows Networking), but the OP specifically seems to be interested in nfs. So I'm confused as to what the real requirements are here. Just a typo and 'nfs' was not really intended?
(**)the nfs protocol doesn't really have the concept of open files, though of course the nfs server must open the file in the file system. |

Btw, psfile allows you to close a remote file; it's like 'net files' with a target system specification in the command syntax.

net files did not work but i figured out the command openfiles will work.
These are netapps filers
so the command "openfiles /disconnect /S servername /ID ####" works after I retreave a list of files by performing a query by "openfiles /query /S servername"
Thanks guys

thanks dave!
this will not work as the OS is netapps based and not a windows system. need a more lower level command interface.

You mean ONTAP?
That is NFS and CIFS.
Originally the filers were NFS and CIFS; then NFS only; then for non-block storage back to NFS and CIFS.
If you were using the fsmgmt.msc snap-in, you were using CIFS.

said by ARIA :thanks dave! this will not work as the OS is netapps based and not a windows system. need a more lower level command interface. It should work just fine. You run it on your Windows system, and it issues a CIFS RPC to the target CIFS server saying 'close this file'. Consequently it should work with any CIFS implementation that supports the necessary RPCs. |

You realize that there is a difference between an Open file and a Locked file?
Do you realize that the command: "openfiles /disconnect /S servername /ID ####" is a Windows/CIFS command?
Do you realize that the command "OpenFiles /Query /S RemoteSystemName" is a Windows/CIFS command?
You can modify my first FOR/DO/LOOP to avoid having to process the OpenFiles/Query command and parsing IDs:
(You need to modify RemoteSystemName to suite:
FOR /F "skip=3" %h IN ('OpenFiles /Query /S RemoteSystemName') DO (OpenFiles /Disconnect /S RemoteSystemName /ID %h)
===================================
Rem FileCloser.CMD
Rem Example with two example servernames: test1 & test2
Rem Untested; there may be a syntax error. Concept piece only.
for %%h in (
"test1"
"test2"
) do (
"psexec -accepteula -e "\\%%~h" "cmd /c for /f "skip=3 tokens=1" %%g in ('OpenFiles /Query /S %%~h') DO (OpenFiles /Disconnect /S %%~h /ID %%g)"
)
exit
===================================
You should also be able to use NET SESSION:
net session /Delete
/delete : Ends the computer's session with /ComputerName and closes all open files on the computer for the session. If you omit /ComputerName, all sessions on the local computer are canceled and all open files are closed.
