<div dir="ltr">Hello together,<div> </div><div>Followed the nice guide here (upgrade from Mitaka to Newton):</div><div> </div><div><a href="https://www.rdoproject.org/install/upgrading-rdo-1/">https://www.rdoproject.org/install/upgrading-rdo-1/</a> </div><div> </div><div>to upgrade a 4 node Mitaka QA environment deployed with packstack (1 controller, 3 compute) to Ocata.</div><div> </div><div>The good news is that all VMs are running on the compute nodes and horizon can be reached with the new nice OpenStack logo :-), but I can't login to horizon anymore. After the package upgarde and following the steps on the mentioned guide above, the call:</div><div> </div><div># systemctl isolate openstack-services.snapshot </div><div>didn't work as expected (it got stuck for a long time and I'd to reboot the controller).One issue which I'd to deal with was the dependency with some Ceph packages:Error: centos-release-ceph-jewel conflicts with centos-release-ceph-hammer-1.0-5.el7.centos.noarch (I'd to erase the Mitaka rpm and disable the Ceph repo and first after that the yum install -y centos-release-openstack-ocata worked) </div><div>So, now after the upgrade if I call openstack-status, some services like nova-api are showing up in "activating" phase and keystone is disabled and there are some 500 internal server errors as provided below. </div><div> </div><div>To be honest, I'm not sure if the direct upgrade from Mitaka to Ocata is the right way and most probably it'd be better to upgarde first to Newton and then to Ocata, right?.</div><div> </div><div>On Mitaka Keystone v2 was activated and as I know in Newton Keystone v3 is the default version.</div><div> </div><div>Now my questions are:</div><div> </div><div>Does the guide above work for upgrading to Ocata at all, e.g. from Newton to Ocata?</div><div>Are there any additional steps which one needs to consider?</div><div>What happens if I create a new packstack answer-file and run a new deployment? (well, I know the answer might be, try it yourself :-))</div><div>Do I need to adjust the nova.conf, keystone.conf files?</div><div> </div><div> </div><div>Thanks for any hints in advance!</div><div>-Arash</div><div> </div><div> </div><div> [root@controller~(keystone_admin)]# openstack-status == Nova services == openstack-nova-api: activating openstack-nova-compute: inactive (disabled on boot) openstack-nova-network: inactive (disabled on boot) openstack-nova-scheduler: activating openstack-nova-cert: activating openstack-nova-conductor: activating openstack-nova-console: inactive (disabled on boot) openstack-nova-consoleauth: activating openstack-nova-xvpvncproxy: inactive (disabled on boot) == Glance services == openstack-glance-api: active openstack-glance-registry: active == Keystone service == openstack-keystone: inactive (disabled on boot) == Horizon service == openstack-dashboard: 301 == neutron services == neutron-server: active neutron-dhcp-agent: active neutron-l3-agent: active neutron-metadata-agent: active neutron-openvswitch-agent: active neutron-metering-agent: active == Cinder services == openstack-cinder-api: active openstack-cinder-scheduler: inactive openstack-cinder-volume: active openstack-cinder-backup: active == Ceilometer services == openstack-ceilometer-api: inactive (disabled on boot) openstack-ceilometer-central: active openstack-ceilometer-compute: inactive (disabled on boot) openstack-ceilometer-collector: active openstack-ceilometer-notification: active == Heat services == openstack-heat-api: active openstack-heat-api-cfn: inactive (disabled on boot) openstack-heat-api-cloudwatch: inactive (disabled on boot) openstack-heat-engine: inactive == Support services == mariadb: active openvswitch: active dbus: active target: active rabbitmq-server: active memcached: active == Keystone users == Traceback (most recent call last): File "/usr/bin/keystone", line 6, in <module> from keystoneclient.shell import main File "/usr/lib/python2.7/site-packages/keystoneclient/shell.py", line 32, in <module> from keystoneclient.contrib.bootstrap import shell as shell_bootstrap File "/usr/lib/python2.7/site-packages/keystoneclient/contrib/bootstrap/shell.py", line 17, in <module> @utils.arg('--user-name', metavar='<user-name>', default='admin', dest='user', AttributeError: 'module' object has no attribute 'arg' == Glance images == Internal Server Error (HTTP 500) == Nova managed services == No handlers could be found for logger "keystoneauth.identity.generic.base" ERROR (InternalServerError): Internal Server Error (HTTP 500) == Nova networks == No handlers could be found for logger "keystoneauth.identity.generic.base" ERROR (InternalServerError): Internal Server Error (HTTP 500) == Nova instance flavors == No handlers could be found for logger "keystoneauth.identity.generic.base" ERROR (InternalServerError): Internal Server Error (HTTP 500) == Nova instances == No handlers could be found for logger "keystoneauth.identity.generic.base" ERROR (InternalServerError): Internal Server Error (HTTP 500)</div></div>
