Hi,
We're currently running Grizzly (going to Havana soon) and we're running
into an issue where if the active controller is ungracefully killed then
nova-compute on the compute node doesn't properly connect to the new
rabbitmq server on the newly-active controller node.
I saw a bugfix in Folsom (https://bugs.launchpad.net/nova/+bug/718869)
to retry the connection to rabbitmq if it's lost, but it doesn't seem to
be properly handling this case.
Interestingly, killing and restarting nova-compute on the compute node
seems to work, which implies that the retry code is doing something less
effective than the initial startup.
Has anyone doing HA controller setups run into something similar?
Chris
