Public bug reported: We have encountered this bug, http://www.spinics.net/lists/linux- nfs/msg17801.html, which was discussed on the linux-nfs mailing list in December 2010. I am reporting the bug here because the discussion on the linux-nfs mailing list seems to have fizzled out and resulted in nothing happening. We are seeing the problem on Ubuntu 10.04 running the 2.6.32-28-generic kernel.
Please see the above link for full details of the problem. We are able to consistently reproduce this problem exactly as described in that original problem report. The only difference is that our NFS server is a NetApp FAS 2040 running ONTAP 8.0.1, whereas the original problem report was using a Solaris NFS server. I marked this bug as a regression since it does not affect older kernels, as described in the discussion on linux-nfs. Indeed, we do not see this problem on CentOS 5.6 running the 2.6.18-238.12.1.el5 kernel. I do not know if this bug was not present in earlier kernels in Ubuntu, as we are recent Ubuntu converts.
