** Description changed:
[Impact]
Need to get this added to the Ubuntu packages in order to safeguard against
missed VRRP transitions due to ip -o monitor not running at the time the
transition occurs. We have seen many cases in the fields where neutron routers
end up as active on multiple l3 agents (via neutron api) which leads to a
number of problems.
[Test Case]
* deploy Openstack (any version that supports l3ha)
* create HA router with max-l3-agents=2
* check neutron l3-agent-list-hosting-router for master location
* on both hosts that are running the l3-agent do
pid=`pgrep -f "/usr/bin/neutron-keepalived-state-change
--router_id=$ROUTER_UUID"`
ps -f --ppid $pid
pkill -f "/usr/bin/neutron-keepalived-state-change --router_id=$ROUTER_UUID"
ps -f --ppid $pid <<<<<<<<<<< this should return nothing now
pkill -f "/var/lib/neutron/ha_confs/$ROUTER_UUID/keepalived.conf"
* without this patch you should now see both agents reporting the router as
"active"
* with the patch this should not happen (once neutron-keepalived-state-change
has been restarted)
[Regression Potential]
- None expected.
+ These patches have already landed in corresponding upstream branches and
therefore have undergone reviews + unit and functional testing upstream,
therefore regression potential is expected to be low.
====================================================================
Recently many L3 HA related functional tests are failing.
The common thing in all those errors is fact that it fails when waiting for
l3 ha router to become master.
