Bug 1642588

Manually installing openvswitch and starting the service prior to the deploy allowed a deploy to complete successfully and configure openvswitch on the overcloud hosts.

*** Bug 1645554 has been marked as a duplicate of this bug. ***

Can we have a status update on this bug?

With https://review.opendev.org/#/c/663989/ the deployment will take care of enabling and starting openvswitch on nodes where the neutron ovs agent is deployed.

Since the problem described in this bug report should be
resolved in a recent advisory, it has been closed with a
resolution of ERRATA.

It looks like we're stilling hitting this with openstack-tripleo-heat-templates-8.4.1-16.el7ost.noarch. Our OSP 13 deploy just completed, but on newly added compute nodes  we see:

[root@neu-17-2-stackcomp ~]# docker ps -f name=neutron
CONTAINER ID        IMAGE                                                                  COMMA

And looking at the logs:

[root@neu-17-2-stackcomp ~]# docker logs neutron_ovs_agent 2>&1 | tail -10
    raise self.last_attempt.result()
  File "/usr/lib/python2.7/site-packages/concurrent/futures/_base.py", line 422, in result
    return self.__get_result()
  File "/usr/lib/python2.7/site-packages/tenacity/__init__.py", line 298, in call
    result = fn(*args, **kwargs)
  File "/usr/lib/python2.7/site-packages/neutron/agent/ovsdb/native/connection.py", line 67, in do_get_schema_helper
    return idlutils.get_schema_helper(conn, schema_name)
  File "/usr/lib/python2.7/site-packages/ovsdbapp/backend/ovs_idl/idlutils.py", line 128, in get_schema_helper
    'err': os.strerror(err)})
Exception: Could not retrieve schema from tcp:127.0.0.1:6640: Connection refused

And on the host:

[root@neu-17-2-stackcomp ~]# systemctl is-active openvswitch
inactive
[root@neu-17-2-stackcomp ~]# systemctl is-enabled openvswitch
disabled

It looks like this hasn't been resolved (or there was some sort of regression)?

openstack-tripleo-heat-templates-8.4.1 is based on final upstream queens release and includes the fix mentioned here:
https://review.opendev.org/#/c/663989/

You can confirm with docker/services/neutron-ovs-agent.yaml having this section in THT:
      host_prep_tasks:
        list_concat:
          - {get_attr: [NeutronLogging, host_prep_tasks]}
          -
            - name: ensure openvswitch service is enabled
              service:
                name: openvswitch
                state: started
                enabled: yes

Which if I read correctly should cover all cases here. So probably different issue, but I will defer to Brent's opinion here

I think the patches should have this covered. Is this still happening Lars?

Brent,

Thanks for checking in. Since this only crops up during initial installs, it's hard to tell. I'm not going to have the chance to try this out myself for a while, so if folks want to go ahead and close this ticket that's fine with me.

Well, I guess it's already closed :)
