What happens if the controller has a network split?
My question, in this scenario where the compute nodes lose connection to the controller primarily the HEAT API?
Scenario diagram:
world | Networker | (switch2) | Compute | (switch1)------------- Controller
Background:
I've been playing around with heat and instance HA with the new HOT template formatting. I have my generic template here, https://raw.githubusercontent.com/andrewklau/openstack-heat-templates/master/base-instance-iha.yaml (https://raw.githubusercontent.com/and...) it's not properly working yet (validation issues), but the main concept should make sense.
In the case scenario where above (switch1) were to fail and go offline for 30 minutes. If I understand correctly, most services shouldn't get effected but the heat component (primarily the IHA) would get hit pretty hard. Are there any case scenarios regarding this?
Thanks.
