Graphviz DOT-based diagram showing the complete storage path: App pods → PVCs (StorageClass/Retain-Policy) → Longhorn replicas → K3s worker nodes → Proxmox hosts. HA analysis annotated with color coding: - Red: SPOF (control-plane on n01, share-manager on n01) - Orange: Degraded on failure (CSI controllers on n02, RWX volumes) - Green: HA covered (2 Longhorn replicas on different Proxmox hosts) Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
