+++ This bug was initially created as a clone of Bug #1272572 +++ Description of problem: When going to System->Defaults in Horizon an 'Error: Unable to retrieve volume limit information.' shows up. Cinder logs show the following: 2015-10-16 19:00:05.262 25704 ERROR cinder.api.middleware.fault [req-79120e7c-360e-4694-a132-e409c4edc2cb 81711f9c9eb24da292ed59647041c422 741b6051f5064e17a3418be64e6a3fcd - - -] Caught error: Authorization failed: Unable to establish connection to http://localhost:5000/v3/auth/tokens Seen in a Packstack installation on Mitaka-1 test day. A similar fix to what is done in tripleo-heat-templates is required for Packstack.
After https://review.openstack.org/253480 was merged, Cinder no longer needed the keymgr/encryption_auth_url parameter set to avoid displaying the error message. However, it seems to require a v3 URL for keystone_token/auth_uri or it still shows the error from time to time.
I have managed to fix the issue on a system installed with RDO Liberty by upgrading the Cinder packages to the latest versions available from Delorean: python-cinderclient-1.4.1-0.20160211140554.2cb21ee.el7.centos.noarch python-cinder-7.0.2-0.20160217192718.1a0bf37.el7.centos.noarch openstack-cinder-7.0.2-0.20160217192718.1a0bf37.el7.centos.noarch My guess is that it may be related to the following Cinder commit, which was merged on February 9: https://github.com/openstack/cinder/commit/bd3b972e72bb17b0a0f08f972a7bcdb39c6dd35f I'm reassigning this to Cinder, to make sure it is properly tracked and included in the next release.
