Bug Description
High level description:
After a reboot the network controller, neutron linuxbridge agent does not create all network links correctly of the tenant networks.
This is behavior is not only on system where the node is rebooted also on nodes that are longer running. And not possible to respawn new networks/dhcp agents/l3 routers
* Pre-conditions:
I was able to reproduce the issue by deleting the vxlan interface of a tenant network and then reboot the node.
After the reboot the interface the namespace for example for the dhcp namespace
- does not get attached to the bridge
- the bridge does not get created
- the vxlan interace does not get created
* Step-by-step reproduction steps
1. Create about till you have about 115 tenant networks
2. reboot the network controller
* Expected output:
Expected behavior is that after the reboot vxlan get recreated and that we see the following:
interface ns-41a5e6e6-
* Actual output:
after the reboot:
* interface ns-41a5e6e6-
* interface tap41a5e6e6-b3@if2 exists
* interface tap41a5e6e6-b3@if2 not attached to any bridge
* bridge brq8c9de29c-e2 does not exists
* vxlan interface does not exists
* Version:
** Openstack Ussuri
** Installed with Openstack ansible version 21.2.6
** neutron version 7.1.1
** Ubuntu Bionic
Perceived severity: The cluster is degrated state where is only possible to new
networks, dhcp agent and l3 router on one of the three network nodes.

Hi - thanks for the report. Can you confirm the linuxbridge agent has started properly, and if there's anything useful in the journal log? Same for the dhcp and l3 agents.
Also, are you running on metal or in lxc?
