The PVC was never actually the blocker

NFS-backed volumes are real network storage, not node-local — a stateful workload had already been running against one from a different node for weeks before anyone checked.

Background

Rebalancing workloads across the cluster stalled on the assumption that a persistent volume pinned its workload to the node that had first claimed it.

Path

Symptom
Workload rebalance stalled
Assumption
assume storage pins the node
Measurement
inspect a workload already running cross-node
Decision
move three services onto the other node

Response

Check a workload already running cross-node against an NFS-backed volume, confirm the constraint does not exist, then move three services onto the other node.
