[Dmitry Makovey <dmakovey@xxxxxxxxx>]

I have tracked error message to:

# grep -nrF "service['updated_at']" /usr/lib/python2.6/site-packages/
/usr/lib/python2.6/site-packages/cinder/utils.py:929:    last_heartbeat = service['updated_at'] or service['created_at']

but now I can't quite figure out what event would trigger update of 'updated_at' column in cinder.services. I see second server references in there though:

*************************** 3. row ***************************
       created_at: 2013-04-17 20:18:33
       updated_at: NULL
       deleted_at: NULL
          deleted: 0
               id: 3
             host: nodeB
           binary: cinder-volume
            topic: cinder-volume
     report_count: 0
         disabled: 0
availability_zone: nova

so it registered itself initially but didn't "update" the record? Now I'm a bit stuck as there are not too many references to updated_at and none of them seems to be relevant to me (most have something to do with glance and volume-to-image transition ?).

If I am to believe that post my setup should "just work" at this point. Could it be because some endpoints are defined as "localhost"? I've added non-127.0.0.0/8 entries for most pertinent endpoints (keystone, cinder*) but I wonder if I need something else as well? Does OpenStack take issue with multiple endpoints defined?
