Hi! At the moment we have dual nodes cluster based on Ganeti and DRBD, this setup provides HA and easy of instance management which we could move from on node to another without shutdown. Next month we are planning to migrate to openstack solution. So the question is how we could deploy openstack cluster with on only two nodes?

Thanks for your reply. I see there are two different nodes in the howtos: Compute and Controller. But what will if one of nodes fails? Will our instances continue to work in this case?

View post of Andrew Law - first link (keepalived daemon). Personally I didn't test it.
