CIFS :: user lost lock on file after time

Hello Forum,

 

Sometimes we notice a strange problem with accessing files, keeping locks and user access to files.

 

Our users got mapped network drive that points to a filer. They open a file (for example an excel sheet) and kept it open.

After a while (for example 3 hours) another user tries to open that file and DOESN'T get a message that this file is in use by the first one.

If the person tries this after a shorter amount of time (for example 10 minutes) it does get a message.

Why?

 

 

I thought that it should have to do with loosing locks, so I think that the protocol (CIFS) forum is the right place for this question.

 

Do you have any idea why users can loose there locks after a while?

Maybe, there is an option for that timeout?

 

 

How to troubleshoot this issue?

 

 

Best regards,

Re: CIFS :: user lost lock on file after time

I have the same issue you were facing before. 

 

The fist user opened a file (DOC), the secound user can open the same file without seeing a message " file in use for editing" 

 

Have you solved this issue ? then how to resolve this issue??

 

Thank you for your help in advance

Re: CIFS :: user lost lock on file after time

This is a known behavior of softwares like Word and Excel (but also some UNIX editors like VI).

When a user opens a document in Word, a temporary file will be created and the user will in fact be working on the temporary copy of the file.
