[rdo-list] Problem with ha-router



Hello all,

I tried to deploy RDO Pike without container on our internal plateform.

The setup is pretty simple :
 - 3 Controller in HA
 - 5 Ceph
 - 4 Compute
 - 3 Object-Store

I didn't used any exotic parameter.
This is my deployment command :

openstack overcloud deploy --templates
  -e environement.yaml
  --ntp-server 0.pool.ntp.org
  -e storage-env.yaml
  -e network-env.yaml
  -e /usr/share/openstack-tripleo-heat-templates/environments/puppet-ceph.yaml
  --control-scale 3 --control-flavor control
  --compute-scale 4 --compute-flavor compute
  --ceph-storage-scale 5 --ceph-storage-flavor ceph-storage
  --swift-storage-flavor swift-storage --swift-storage-scale 3
  -e scheduler_hints_env.yaml
  -e /usr/share/openstack-tripleo-heat-templates/environments/network-isolation.yaml
  -e /usr/share/openstack-tripleo-heat-templates/environments/puppet-pacemaker.yaml

        '/dev/sdc': {}

scheduler_hints_env.yaml
parameter_defaults:

    CephStorageSchedulerHints:
        'capabilities:node': 'ceph-storage-%index%'
    ObjectStorageSchedulerHints:
        'capabilities:node': 'swift-storage-%index%'

After a little use, I found that I found that one controller is unable to get active ha-router and I got this output :

neutron l3-agent-list-hosting-router XXX
+--------------------------------------+------------------------------------+----------------+-------+----------+
| id                                   | host                               | admin_state_up | alive | ha_state |

+--------------------------------------+------------------------------------+----------------+-------+----------+

So each time a router is schedule on this controller I can't get an active router. I tried to compare the configuration but everything seems to be good. I redeployed to see if it help, and the only thing that change is the controller where the ha-router are stuck.

The only message that I got is fron OVS :

2017-10-20 08:38:44.930 136145 WARNING neutron.agent.rpc [req-0ad9aec4-f718-498f-9ca7-15b265340174 - - - - -] Device Port(admin_state_up=True,allowed_address_pairs=[],binding=PortBinding,binding_levels=[],created_at=2017-10-20T08:38:38Z,data_plane_status=<?>,description='',device_id='a7e23552-9329-4572-a69d-d7f316fcc5c9',device_owner='network:router_ha_interface',dhcp_options=[],distributed_binding=None,dns=None,fixed_ips=[IPAllocation],id=7b6d81ef-0451-4216-9fe5-52d921052cb7,mac_address=fa:16:3e:13:e9:3c,name='HA port tenant 0ee0af8e94044a42923873939978ed42',network_id=ffe5ffa5-2693-4d35-988e-7290899601e0,project_id='',qos_policy_id=None,revision_number=5,security=PortSecurity(7b6d81ef-0451-4216-9fe5-52d921052cb7),security_group_ids=set([]),status='DOWN',updated_at=2017-10-20T08:38:44Z) is not bound.

Any Idea ?
