CASE ANALYSIS
Scenario
A two-node Proxmox VE cluster requires a separate, redundant Corosync network to avoid split-brain and an external QDevice for quorum.
Key decisions
- Redundant ring switches for Corosync traffic
- External QDevice to break ties in 2-node quorum
- Shared storage reachable from both nodes
When to reuse this
Reuse for any 2-node Proxmox VE cluster diagrams where split-brain prevention and quorum design matter.
