This change serialises the neutron l3 agent restart process and adds a user configurable delay between restarts. This can prevent connectivity loss due to all agents being restarted at the same time. Routers increase the recovery time, making this issue more prevalent. Change-Id: I3be0ebfa12965e6ae32d1b5f13f8fd23c3f52b8c

fixes:
|
|
- |
|
|
In HA mode, parallel restart of neutron-l3-agent containers will cause
|
|
a network outage. Adding routers increases the recovery time. This
|
|
release makes restarts serial and adds a user-configurable delay to ensure
|
|
each agent is returned to operation before the next one is restarted.
|
|
|
|
The default value is 0. A nonzero starting value would only result in
|
|
outages if the failover time was greater than the delay, which would be
|
|
more difficult to diagnose than consistent behaviour.
