This bug is reported at https://bugs.launchpad.net/horizon/+bug/1053488, one potential way to fix it is proposed at https://review.openstack.org/14801
2012/11/13 Gabriel Hurley <[email protected]> > That is actually the manifestation of a bug in Nova that was addressed > very late in Folsom. The short version is that Nova inconsistently scoped > the ownership of volumes vs. instances so it was possible for an admin user > to view a mixed set of resources which could lead to the scenario you hit > where things are in one list but not the other. I’m not sure if there’s any > plans to backport the fixes from Nova. A patch could probably be worked up > for the stable/essex Horizon branch that would avoid the keyerror (see the > state of that code in Folsom: > https://github.com/openstack/horizon/blob/stable/folsom/horizon/dashboards/nova/volumes/views.py#L68), > but it would be papering over what is inherently a broken situation in > Nova.**** > > ** ** > > My advice from back in the Essex days was that you should be wary of using > an “admin” user in the “Project” dashboard since the underlying APIs didn’t > handle it correctly.**** > > ** ** > > Alternatively, the Folsom Horizon release is actually backwards-compatible > to an Essex stack, so you could try running Folsom Horizon which is less > subject to many issues.**** > > ** ** > > Hope one of these suggestions helps!**** > > ** ** > > **- **Gabriel**** > > ** ** > > *From:* > [email protected][mailto: > [email protected]] *On > Behalf Of *Christian Parpart > *Sent:* Monday, November 12, 2012 3:37 AM > *To:* <[email protected]> > *Subject:* [Openstack] Essex Dashboard: KeyError at > /nova/instances_and_volumes/**** > > ** ** > > Hey all,**** > > ** ** > > since quite some weeks I am getting an error page instead of the > "Instances and Volumes" page in the**** > > Essex Horizon Dashboard with the above title and the below detailed error > output:**** > > ** ** > Environment:**** ** ** Request Method: GET**** Request URL: > http://controller.rz.dawanda.com/nova/instances_and_volumes/**** ** ** Django > Version: 1.3.1**** Python Version: 2.7.3**** Installed Applications:**** > ['openstack_dashboard',**** 'django.contrib.sessions',**** > 'django.contrib.messages',**** 'django.contrib.staticfiles',**** > 'django_nose',**** 'horizon',**** 'horizon.dashboards.nova',**** > 'horizon.dashboards.syspanel',**** 'horizon.dashboards.settings']**** > Installed > Middleware:**** ('django.middleware.common.CommonMiddleware',**** > 'django.middleware.csrf.CsrfViewMiddleware',**** > 'django.contrib.sessions.middleware.SessionMiddleware',**** > 'django.contrib.messages.middleware.MessageMiddleware',**** > 'openstack_dashboard.middleware.DashboardLogUnhandledExceptionsMiddleware', > **** 'horizon.middleware.HorizonMiddleware',**** > 'django.middleware.doc.XViewMiddleware',**** > 'django.middleware.locale.LocaleMiddleware')**** ** ** ** ** Traceback:** > ** File "/usr/lib/python2.7/dist-packages/django/core/handlers/base.py" > in get_response**** 111. response = > callback(request, *callback_args, **callback_kwargs)**** File > "/usr/lib/python2.7/dist-packages/horizon/decorators.py" in dec**** 40. > return view_func(request, *args, **kwargs)**** File > "/usr/lib/python2.7/dist-packages/horizon/decorators.py" in dec**** 55. > return view_func(request, *args, **kwargs)**** File > "/usr/lib/python2.7/dist-packages/horizon/decorators.py" in dec**** 40. > return view_func(request, *args, **kwargs)**** File > "/usr/lib/python2.7/dist-packages/django/views/generic/base.py" in view*** > * 47. return self.dispatch(request, *args, **kwargs)**** File > "/usr/lib/python2.7/dist-packages/django/views/generic/base.py" in dispatch > **** 68. return handler(request, *args, **kwargs)**** File > "/usr/lib/python2.7/dist-packages/horizon/tables/views.py" in get**** > 105. handled = self.construct_tables()**** File > "/usr/lib/python2.7/dist-packages/horizon/tables/views.py" in > construct_tables**** 96. handled = self.handle_table(table)* > *** File "/usr/lib/python2.7/dist-packages/horizon/tables/views.py" in > handle_table**** 68. data = self._get_data_dict()**** File > "/usr/lib/python2.7/dist-packages/horizon/tables/views.py" in _get_data_dict > **** 37. self._data[table._meta.name] = data_func()**** File > "/usr/lib/python2.7/dist-packages/horizon/dashboards/nova/instances_and_volumes/views.py" > in get_volumes_data**** 74. att['instance'] = > instances[att['server_id']]**** ** ** Exception Type: KeyError at > /nova/instances_and_volumes/**** Exception Value: > u'8aa2989e-85ea-4975-b81b-04d06dbf8013'**** > > > ---------------------------------------------------------------------------------------------------------------------------- > **** > > ** ** > > now I wonder in how far that is a bug in the software and/or whether I > have an invalid entry in my nova database that**** > > I can fix by hand.**** > > ** ** > > if so, does anyone know how to actually work around this?
