Did this issue occur in a previous version of Ubuntu, or is this a new
issue?

Would it be possible for you to test the latest upstream kernel? Refer
to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest
v3.16 kernel[0].

If this bug is fixed in the mainline kernel, please add the following
tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag:
'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".


Thanks in advance.

Title:
  Ubuntu 13.04 unable to mount Nexenta CIFS shares

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  After upgrading to Ubuntu 13.04 I have experienced some compatibility
  issues when mounting CIFS shares on the Ubuntu 13.04 workstation. The
  following systems were tested:

   * Windows 2003 server CIFS shares: Success
   * EMC VNX CIFS shares: Success
   * Ubuntu 10.04.2 CIFS shares: Success
   * Nexenta CIFS shares: Failed

  All the same shares continue to work from Ubuntu 12.10 systems. So in
  Ubuntu 13.04, there has arisen a CIFS compatibility issue between
  Ubuntu and Nexenta. I have also been in touch with our Nexenta
  supplier, and they have set up a new machine with Nexenta OS with a
  CIFS share, and a new install of Ubuntu 13.04, and they reproduced the
  same error. My environment uses AD authentication, but the issue was
  reproduced without AD authentication, so that's not it.

  Here's the syslog excerpt from the failed mount, /proc/fs/cifs/cifsFYI
  was set to 1 (removed date and hostname for brevity):

  To summarize, a change that occurred between Ubuntu 12.10 and Ubuntu
  13.04 is causing compatibility issues with the Nexenta CIFS shares. I
  can't say from the information I have whether it's Ubuntu or Nexenta
  that is not compliant, but if it is Ubuntu, this may be affecting
  other systems as well.
