OK, it turns out that my DC/network provider does not allow for gratuitious arps. However, they allow for IPs that I can assign via API to any server. If I were using keepalived, I could trigger a script that calls their API, whenever a node goes down and have the master “claim” the IP. Is there a similar mechanism/hook in harvester so that if a node goes down, the next node that takes over will perform an API call to claim the IP (since gratuitous ARPs don’t work)?
