CIFS mount does not update file size for opened (for read) files

Radu, are you still seeing this issue with 6.06 or 6.10?

Yes, I still see this in 6.06.
One correction for the steps above: 'mail/test' should be just 'test'.
Basically, as long as a file is opened for reading on the client machine, its content and attributes are not updated, even if it changes on the server.
This happens for cifs only.

I just tested this on 6.10 and the problem is still there.

Tested this in 7.04, still a problem.
I have spoken to people on the #samba channel, apparently this is a known problem and a fix is in the works. No idea when it would migrate into the kernel though.

Is it this bug perhaps https://bugzilla.samba.org/show_bug.cgi?id=4525 ? Seems to still be a problem in the 2.6.20 kernels. Could someone who has experienced this try with gutsy which has 2.6.22?

Is this still a problem with you in hardy?

Thanks
chuck

I'm having that problem too.

I'm using Ubuntu 9.10 - Karmic Koala, all updated.

I do mount a samba share with this line in /etc/fstab:
//192.168.0.17/www /media/svn cifs auto,iocharset=utf8,uid=xxx,gid=users,credentials=/root/.cifscredentials,file_mode=0775,dir_mode=0775 0 0

version of mount:
$ mount -V
mount from util-linux-ng 2.16 (with libblkid and selinux support)

I'm editing files with SciTE Version 1.76
Scite does control if a file has changed by regularly checking the "last changed" date. If all changes are saved and the file has changed, scite reloads ist. If the buffer is dirty (unsaved changes) scite asks if i wanna reload the file. This works perfectly on lokal drives.

If working on the mount point mentioned above, scite does neither automatically reload clean buffers, nor ask me if i want to reload dirty buffers.

If you need any additional information, just let me know.

Switching to kernel since this is a CIFS issue.

Hi Radu,

Please be sure to confirm this issue exists with the latest development release of Ubuntu. ISO CD images are available from http://cdimage.ubuntu.com/releases/lucid . If the issue remains, please run the following command from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p linux 25031

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.

try adding the "directio" option to your fstab or your mount commandline (eg mount -t cifs -o username=xyz,password=abc,directio)

I have the same problem here with several Lucid machines acessing one share. It does not seem to be reproduceable, happens only sometimes.

Thank you for reporting this bug.

Does this occur in Maverick?
