Story Crater Bot

Adds expand-replicas-job.yaml: PostSync hook Job that: - Waits for all 3 Longhorn nodes to be Ready - Patches every volume with numberOfReplicas < 3 to 3 - Runs idempotently on every longhorn-config sync (BeforeHookCreation deletes previous job, so re-runs are safe) This ensures existing 1-replica volumes (created before the HA setup) get expanded automatically via GitOps, not via manual kubectl patch. Why PostSync: needs to run AFTER the taint-toleration setting and Node CRDs are applied, otherwise there aren't 3 nodes available yet and the expansion would fail (Longhorn can't create replicas on nodes that don't exist).

# Longhorn deployed via bootstrap script (cluster-config/longhorn_bootstrap.sh).

# These manifests configure it post-bootstrap: WFFC StorageClass (default),

# Prometheus ServiceMonitor, taint toleration for control-plane nodes, explicit

# Node CRDs for cp-2/cp-3, and a PostSync hook Job that expands all existing

# volumes from 1→3 replicas (runs after nodes are Ready).
