I have an issue about openstack network provider.

I can show it in host system when I create flat network.  

[sysadmin@controller-0 ~(keystone_admin)]$ system datanetwork-list
+--------------------------------------+---------------+--------------+------+
| uuid                                 | name          | network_type | mtu  |
+--------------------------------------+---------------+--------------+------+
| 20b6055a-5a5a-4789-8ceb-b43ecb1512c0 | physnet-sriov | flat         | 1500 |
| 25fd1e7d-1871-483f-822a-9da1e10eb31f | physnet0      | vlan         | 1500 |
+--------------------------------------+---------------+--------------+------+

But My neutron-server pod didnt update the config.

[root@neutron-server-66dd786c49-rh4kb /]# cat /etc/neutron/plugins/ml2/ml2_conf.ini
[agent]
extensions =
[ml2]
extension_drivers = port_security
mechanism_drivers = openvswitch,sriovnicswitch,l2population
path_mtu = 0
physical_network_mtus = physnet0:1500
tenant_network_types = vlan,vxlan
type_drivers = flat,vlan,vxlan
[ml2_type_flat]
flat_networks =
[ml2_type_vxlan]
vni_ranges =
vxlan_group =
[ovs_driver]
vhost_user_enabled = true
[securitygroup]
firewall_driver = openvswitch

Maybe the reason is that my host system is degraded

[sysadmin@controller-0 ~(keystone_admin)]$ system host-list
+----+--------------+-------------+----------------+-------------+--------------+
| id | hostname     | personality | administrative | operational | availability |
+----+--------------+-------------+----------------+-------------+--------------+
| 1  | controller-0 | controller  | unlocked       | enabled     | degraded     |
+----+--------------+-------------+----------------+-------------+--------------+

And I found out my  subfunction_availability is fail and  subfunction_operif disabled. It will make my controller-0 degraded?

How can I fix this bug?

Best Regards
