Closes the ghost-disk doom loop by construction (failed detach -> orphan scsiN
with no VolumeAttachment -> invisible oversubscription -> query-pci wedge).
Every 15min csi-ghost-reconcile compares each worker VM's real scsi disks
(Proxmox API) vs k8s VolumeAttachments and safely detaches ghosts (PUT
.../config delete=scsiN -> frees the LUN slot, retains the LV).
- detection mirrors cluster-health check #47
- SAFETY: only vm-9999-pvc scsi with no matching VA; 60s re-confirm; per-run cap 5
- scoped CSI API token (VM.Config.Disk), not root SSH; k8s API via injected ClusterIP
- verified live: read 66 VAs, 0 ghosts, no false positives
- pushes csi_ghosts_detected/detached to Pushgateway
