Title:
Ubuntu 13.04 unable to mount Nexenta CIFS shares
Status in “linux” package in Ubuntu:
Expired
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.
