# Shared NFS filesystem for Funnel server + all worker pods.
#
# Backed by in-cluster NFS server (Phase 3 installs it as Helm release
# "nfs-shared" in namespace "nfs-system").  The NFS pod runs on the
# system node, backed by a Cinder block volume (csi-cinder-high-speed).
#
# Access mode: ReadWriteMany — all pods mount the same directory at /mnt/shared.
#
# Architecture:
#   Cinder PVC (RWO, system node)
#   → NFS pod (nfs-system ns, system node)
#   → Service ClusterIP (nfs-shared-nfs-server-provisioner.nfs-system)
#   → funnel-shared-pvc (RWX, StorageClass: nfs-shared)
#   → Funnel server Deployment + every Funnel worker Job  → /mnt/shared
#
# To inspect the mount inside a running worker:
#   kubectl exec -n ${TES_NAMESPACE} <worker-pod> -- ls /mnt/shared
