Description of problem:

This is in reference to upstream bug https://bugs.launchpad.net/cinder/+bug/1490845, "Netapp: Image cloning unsuccessful, "need more than 2 values to unpack" " 

==

The problem seems to be that _get_capacity_info() in drivers/netapp/dataontap/nfs_base.py returns a tuple, whereas in drivers/nfs.py three values are expected:

        total_size, total_available, total_allocated = \
            self._get_capacity_info(nfs_share)

A customer is currently testing the following on OSP 7. This bug was supposed to be fixed in the kilo release, but they are still encountering it in OSP 7. 

According to the customer, NetApp communicated the following to them at some point: "The word from Red Hat is that this fix should be included in their next OSP7 maintenance release, due out this month"

ACcording to version numbers, it seems that this bug is fixed in OSP 8. However, in OSP 7, it is only fixed in cinder-2015.1.3


Version-Release number of selected component (if applicable):
The current versions in OSP 7 is
OSP 7: 2015.1.2-5
[root@overcloud-controller-1 ~]# rpm -qa | grep cinder
python-cinderclient-1.2.1-1.el7ost.noarch
python-cinder-2015.1.2-5.el7ost.noarch
openstack-cinder-2015.1.2-5.el7ost.noarch


Can we get an update to cinder-2015.1.3 for OSP 7?
