Reading files caused it become modified?

Our TeamSite 552 is hosted on Windows. Some of our developers are using linux machine, and they can mount to the TeamSite backing store to read files directly via the mounted drive. Eachtime when a file is read through the mounted drive, the file is indicated as modified even if the developer is just reading the file without modifing the file. Any idea why?

Try turning off your anti-virus software briefly, and see if
the problem goes away.

I have heard of this happening to another customer once.

If it stops the problem, you might want to talk to technical
support and see what they say.

Also check into the application(s) being used to look at the file(s) - some editing applications modify attributes of the file (besides, though including, last access time) which might be causing the backing store to assume that the file was modified. If this is the case, you may have to develop a procedure whereby the users copy the file to their local disk before running the editing application on it (or go through TeamSite and download the file via LaunchPad)

Our TeamSite server does not have any anti-virus program running. I don't think this problem is caused by the anti-virus program.

We have done various testing and try to find out what changes the file. However, we do notice that even if we use "cat" to view a file content or "cp" to copy files that could cause the file showing on the TeamSite GUI as being modified. This problem only occur if we try to access files via a Linux machine. We do not have the same problem to access files via a Windows machine.

you don't say what method the Linux clients are using to access the TeamSite/Windows server.

I'm going to hypothesize that your clients are using the native Linux SMBfs, and there's something in the Linux SMBfs that is trying to change the access time on the file, thus causing TeamSite to think the files are modified. If this is the case, it really sounds to me like a Linux problem -- applying Posix semantics to a non-Posix filesystem.

you should investigate whether there's a "noatime" option for the mount_smbfs command; that might solve your problem.

Our developers are using SuSE and Debian Linux. I'll ask them to look into whether there is a "noatime" option for the mount command.
