Introduction
This article explores how to build a two-node cluster with HA enabled under Proxmox. HA is generally recommended to be deployed on at least three nodes to prevent strange behaviours and potentially lethal data incoherences (for further info look for "Quorum". Nevertheless, with some tweaking, it is also possible to successfully use Proxmox to run on a two-node cluster.
Although in the case of two-node clusters it is recommended to use a third, shared quorum disk partition, Proxmox allows to build the cluster without it. Let's see how.
