commit 438808f161044d7d2cb25b3a4dc783c181493da4 Author: Rodolfo Alonso <[email protected]> Date: Tue Feb 11 17:52:00 2025 +0000 Revert "Track all interfaces in Keepalived" This reverts commit bee07defacf61ccef19adbe54677b0a0a00ae65b. Reason for revert: The only interfaces tracked by keepalived are the HA interfaces. The fixed IP / floating IPs / routes are linked to the internal router interfaces or the gateway interface, that are interfaces not tracked by keepalived. These IP addresses / routes should have the suffix "no_track" in the configuration entry. This is commented in [1], when the keepalived VIP HA configuration was fixed, excluding any IP address other than the VIP of the HA interface, that are placed in the "virtual_ipaddress_excluded" and belong to no tracked interfaces.

Engineering Team, which is subscribed to neutron. https://bugs.launchpad.net/bugs/2097770 Title: [ML2/OVS] Detaching floating ip of instances makes Neutron L3 routers failover Status in neutron: Fix Released Bug description: When a floating ip of an instance gets detached, the router (L3, in HA mode) that the instance uses gets failed-over to different L3 agent causing disruption on tenant network. Pre-condition: Number of VMs: 42 Number of routers: 44 User-role: Both member and admin Steps to reproduce. 1. Prepare any network that is connected to external network with any router. 2. Spawn a VM on the network and assign a floating ip 3. Prepare monitoring router network agent failover e.g. ``watch "openstack network agent list --long --router <router id>"`` (on API reachable node) or ``ip netns exec qrouter-<router id> tcpdump -i <ha interface>`` on node where Neutron L3 agent is running. 4. Detach the floating ip of the VM. Expected result: No failover happens to the router Actual result: Failover can be observed. This bug was reproduce-able from systems on Antelope and Caracal releases that use ML2/OVS. Caracal Host OS: 5.14.0-503.16.1.el9_5.x86_64 Antelope Host OS: 5.14.0-362.13.1.el9_3.x86_64 To manage notifications about this bug go to: https://bugs.launchpad.net/neutron/+bug/2097770/+subscriptions -- Mailing list: https://launchpad.net/~yahoo-eng-team Post to : [email protected] Unsubscribe : https://launchpad.net/~yahoo-eng-team More help : https://help.launchpad.net/ListHelp
