Deploy topolvm/pvc-autoresizer controller that monitors kubelet_volume_stats via Prometheus and auto-expands annotated PVCs. Annotated all 9 block-storage PVCs (proxmox-lvm) with per-PVC thresholds and max limits. Updated PVFillingUp alert to critical/10m (means auto-expansion failed) and added PVAutoExpanding info alert at 80%.
