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:
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.
