CIFS Mount and Tar Issue

[tonyswu]

Hi,

We have a Windows Server 2012 SMB share mounted on a Centos 6.4 server using autofs via cifs mount. Sporadically we see issues with tar command where it would generate the following error:

tar: file changed as we read it

This causes our automatic script to fail intermittently. Some Google searches point this error to mtime with CIFS, but doesn't provide concrete solution. Has anyone run into this before and might have a solution?

Thanks very much.

I'd more suspect that Windows is writing to the file during your tar operation - perhaps a user or maybe cached data (write-behind). If so, maybe copying the file to another name and then tar that one may help.

- FWIW

Hi tonyswu,

I have the same problem to. Did you find a solution for that?

Thank you very much for your answer.
