Removes duplicate longhorn-kafka StorageClass managed by Kafka chart.
All applications now use single 'longhorn' StorageClass (3 replicas, Immediate binding).
Changes:
- Kafka chart: use 'longhorn' instead of 'longhorn-kafka'
- Delete Kafka StorageClass template (no longer needed)
- Update longhorn-storageclass.yaml to match deployed config (Immediate, not WaitForFirstConsumer)
Existing Kafka PVCs remain bound to old longhorn-kafka StorageClass (safe - no data loss).
New PVCs will use unified 'longhorn' StorageClass.
Root cause: Longhorn refuses to schedule replicas on nodes without spec.name
field. talos-cp-1 was auto-discovered (has spec.name), but cp-2/cp-3 were
manually created CRDs without it.
Error: 'no node name provided to check node down or deleted'
Fix: Add spec.name matching metadata.name for both nodes.
Changes:
- k8s/infrastructure/longhorn/longhorn-taint-toleration.yaml: new Setting
to tolerate node-role.kubernetes.io/control-plane:NoSchedule taint,
allowing Longhorn DaemonSet to run on cp-2/cp-3 (not just cp-1)
- k8s/infrastructure/longhorn/longhorn-nodes.yaml: explicit Node CRDs for
talos-cp-2 and talos-cp-3 (auto-discovery doesn't work when nodes have
taints; these define /var/lib/longhorn as the storage path)
- k8s/infrastructure/longhorn/longhorn-wffc-storageclass.yaml: bump
numberOfReplicas from 1→3 (true HA: each volume gets 3 copies across
3 nodes; if one node fails, 2 others still have the data)
- k8s/infrastructure/longhorn/kustomization.yaml: add new resources
Root cause: Longhorn was only running on talos-cp-1 (.213) because cp-2/cp-3
have the control-plane taint and Longhorn DaemonSet had no matching toleration.
Every workload with a PVC was forced to schedule on cp-1 (via nodeSelector or
implicit co-location with the storage), defeating the entire purpose of a 3-node
HA cluster.
With this fix:
- Longhorn manager runs on all 3 nodes
- Storage is replicated 3x (erasure-coded across nodes)
- Pods can schedule on any node without PVC attachment failures
- True HA: lose 1 node, cluster still serves all volumes
