In this video, I upgrade my old 2-node Proxmox cluster into a proper 3-node Proxmox cluster with Ceph storage. I’ll show why the old QDevice setup was useful for learning, where it started to fall apart for real high availability, and how Ceph changes the way VM storage works in a Proxmox cluster. We’ll go through the Ceph installation, monitors, managers, OSDs, RBD storage, pool settings, placement groups, and finally a live migration test to see if the VM can move between nodes while staying online.
