Sep 1, 20252025-09 monthly summary for lf-edge/eve focusing on reliability, resource optimization, and lifecycle resilience. Key features delivered include Tie Breaker Node Reservation for EVE clustering to reserve designated nodes for essential cluster functions (etcd quorum) and to prevent core workloads from scheduling on these nodes. This feature also controls storage behavior by selecting a storage class with fewer replicas (2) for longhorn replicas on tie-breaker nodes, reducing contention and failure risk. Addressed Kubernetes hostname compatibility by introducing convert_to_k8s_compatible to normalize node names to lowercase hyphenated forms compatible with Kubernetes hostname conventions, improving NDM verification and descheduler processing. Fixed boot-sequence issues by ensuring the /var/lib/all_components_initialized flag is recreated after conversions between single-node and cluster modes using an added touch in cluster-init.sh. These changes collectively improve cluster stability, resource utilization, and lifecycle reliability, enabling safer upgrades and node conversions.
