[Corey Bryant]

Hello Luciano, or anyone else affected,

Accepted cinder into xena-proposed. The package will build now and be
available in the Ubuntu Cloud Archive in a few hours, and then in the
-proposed repository.

Please help us by testing this new package. To enable the -proposed
repository:

  sudo add-apt-repository cloud-archive:xena-proposed
  sudo apt-get update

Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, and change the tag
from verification-xena-needed to verification-xena-done. If it does not
fix the bug for you, please add a comment stating that, and change the
tag to verification-xena-failed. In either case, details of your testing
will help us make a better decision.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in
advance!

Bug description:
  =========== Bug description =============

  The utility function 'qos_min_feature_name' computes the QOS by
  concatenating a prefix to a node name. However, under some
  circumstances, it's possible that the node name is `None`, thus
  raising a TypeError. This can happen for example, if the
  'storage.aggregate' feature is not present (or the user doesn't have
  privileges for it), which leads to an always-None node_name (see the
  method '_get_ssc_aggregate_info' in
  volume/drivers/netapp/utils/capabilities:270)

  An easy fix is to check for `None`, and if so, return an empty string.

  [Regression Potential]

  It's possible that a user may expect the QOS to be non-empty and make
  some assertions based on that assumption. In addition, a user may
  expect an exception of type `TypeError` to be raised when the node name
  is None.
