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.
