Description Yogev Rabl 2014-07-07 08:56:14 UTC 
Description of problem:
When the Glance is configure to work with rbd backend (Ceph) & the Rados packages (python-ceph) are not installed the Error that the Glance's logs show is: 

2014-07-07 11:28:27.982 2222 TRACE glance.api.v1.upload_utils Traceback (most recent call last):

Instead of catching an import error, the Glance should fail on the count of lack of Rados packages.  


Version-Release number of selected component (if applicable):
python-glance-2014.1-4.el7ost.noarch
python-glanceclient-0.12.0-1.el7ost.noarch
openstack-glance-2014.1-4.el7ost.noarch


How reproducible:
100%

Steps to Reproduce:
1. Configure the glance to work with rbd backend (see http://ceph.com/docs/master/rbd/rbd-openstack/?highlight=openstack). without installing the python-ceph packages.
2. try to create a new image.


Actual results:
The Glance catch an import error.

Expected results:
The Glance should alert that the Rados packages are missing.

Ken/Alfredo,

Any updates?
Comment 15 Flavio Percoco 2015-08-19 07:59:50 UTC 
We've taken a different route upstream and we're re-arrenging how exra dependencies are handled.

I'll close this bug since it's not of any use downstream.
