You mean, you lost both (all) agents? In this case, yes you'd need to
resurrect the agents or move the networks to another available agent.

If you want rescheduling, you need a script to do it.
There is a feature for that behavior in Juno, but only for the L3 agent. [1]

Hi Armando,
Sort of... but what happens when the second one dies? If one DHCP agent
dies, I need to be able to start a new DHCP agent on another host and take
over from it. As far as I can tell right now, when one DHCP agent dies,
another doesn't take up the slack.
I have the same problem wit L
As far as I can tell when you specify:
dhcp_agents_per_network = X > 1
The server binds the network to all the agents (up to X), which means that
you have multiple instances of dnsmasq serving dhcp requests at the same
time. If one agent dies, there is no fail-over needed per se, as the other
age
We currently have a mechanism for restarting the DHCP agent on another
node, but we'd like the new agent to take over all the old networks of the
failed dhcp instance. Right now, since dhcp agents are distinguished by
host, and the host has to match the host of the ovs agent, and the ovs
agent's h
No, unfortunately when the DHCP agent dies there isn't automatic
rescheduling at the moment.
