Public bug reported: When enabling allow_automatic_l3agent_failover in the neutron config, neutron does not automatically reschedule routers with the HA parameter.
In https://github.com/openstack/neutron/blob/master/neutron/db/agentschedulers_db.py#L131, neutron loads all downed agents into the down_bindings list and then iterates over it. This list gets populated in this method: https://github.com/openstack/neutron/blob/master/neutron/objects/l3agent.py#L55 Here, a SQL query gets generated that specifically excludes routers that have the HA-parameter (l3_attrs.RouterExtraAttributes.ha) set to something other than false or NULL. This behavior has always been the case and got introduced in https://github.com/openstack/neutron/commit/7e51f2aea517e1431b9a860c45761c057710f5b2#diff-c1382d923846002c27484cca55e555689da1e08c22f1f8a0343726fd881e86ce. Is there a specific reason for why HA routers get excluded? If not, this conditional in the SQL statement can be removed. ** Affects: neutron Importance: Undecided Status: New -- You received this bug notification because you are a member of Yahoo!
