Description Udi Shkalim 2018-02-14 11:46:46 UTC

Description of problem:
On an HA setup 3 controllers 1 compute created a network, subnet, router and booted an instance.
When I restart the openstack-neutron-l3-agent container or even hard reset of the controller can also cause the L3 HA to fail by more then one active router:

How reproducible:
100%

Steps to Reproduce:
1. Deploy HA setup with containers
2. Populate OC with network and a router
3. restart the l3 container

Actual results:
router set to active on more then one controller

Expected results:
router will remain active only on one controller

Comment 4 anil venkata 2018-02-27 11:45:47 UTC

Hi Udi

L3 agent will update HA router status,
1) to "standby" [1] on agent start. Then after syncing all routers, starting keeplaived processes and wiring the router ports, l3 agent will again update the new status.
2) periodically(through periodic task) if the router status with the agent not matching with the DB.

So please check if the l3 agent started successfully before checking the router status.

Hi Anil,

Thanks for the information. I'll check the status in addition to waiting time Bernard suggested.

Thanks,
Udi

Issue still remain after 6 min and all agents are up.

Can you please check the HA network port status also?

Marking it as a duplicate of https://bugzilla.redhat.com/show_bug.cgi?id=1527130. What's happening is that you're restarting the L3 agent container of the active replica, which kills keepalived (This is the root cause of the bug, as detailed in 1527130). A backup spins up (since it stopped receiving VRRP hello messages from the node that keepalived died on), but the namespace and IPs still exist on the original node, so we end up with two actives. Fixing 1527130 will also fix this bug.
