Subject: [PATCH] f1-stream: migrate PVC from proxmox-lvm to NFS
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Wave 1 LUN-cap relief. The PVC stores 5 small JSON state files
(health_state, schedule, scraped_links, sessions, streams) and a
lost+found — total 30KB, no DB, regenerable from upstream APIs.

Standard scale-to-0 → rsync → swap pattern (deployment was at
replicas=1). Pod came back up on k8s-node4 (now Ready again).

Net: -1 SCSI LUN on k8s-node1 (was the previous host).
