Update: clean keepalived and radvd instances after pcs cluster stop
Older neutron versions have a bug which makes them leave keepalived and radvd running even after all neutron services are stopped, preventing neutron router failover from happening. Router can then get stuck on the inactive node, like this: [stack@instack ~]$ neutron l3-agent-list-hosting-router default_router +--------------------------------------+------------------------------------+----------------+-------+----------+ | id | host | admin_state_up | alive | ha_state | +--------------------------------------+------------------------------------+----------------+-------+----------+ | 48ca9477-b93b-4305-9e6d-9f1c5d3388f0 | overcloud-controller-1.localdomain | True | :-) | standby | | eba0575c-654f-4da6-b1cd-f7fdf1cd3726 | overcloud-controller-2.localdomain | True | :-) | standby | | 68815390-251f-4425-a5f8-38bdbf3bdb90 | overcloud-controller-0.localdomain | True | xxx | active | +--------------------------------------+------------------------------------+----------------+-------+----------+ We need to kill the leftover processes manually to prevent the state described above from happening.
