Monthly summary for 2026-04 highlighting key features delivered, major bugs fixed, and overall impact across two repositories: stackhpc/ansible-slurm-appliance and stackhpc/stackhpc-kayobe-config. Focused on usability improvements, reliability hardening, and storage/networking improvements that drive faster deployments, better reliability, and reduced operational risk.

March 2026 delivered two high-impact changes in stackhpc/stackhpc-kayobe-config that advance reliability and deployment flexibility. A bug fix enforces the presence of required secrets for Microsoft Teams webhook URLs, reducing misconfigurations and ensuring consistent alert delivery. A new Ironic tunings mixin environment was introduced, enabling default and policy-based customization to support gradual mid-cycle adoption and greater deployment flexibility. These changes strengthen operational governance, improve notification reliability, and empower teams to tailor deployments without touching core code.

February 2026 (2026-02) performance summary: Delivered two high-impact features and two security/observability enhancements across stackhpc-kayobe-config and ansible-slurm-appliance, plus a critical bug fix improving cloud infrastructure reliability. Key outcomes include centralized upgrade guidance for Ubuntu Noble, clearer error feedback in scripts, hardened SSHD file permissions, persistent logging for cloud images, and a fix for Ironic rebuild issues in Nova Compute API >= 2.93. These efforts reduce maintenance overhead, improve troubleshooting, and strengthen security posture, while expanding CI-visible improvements and release documentation. Technologies demonstrated: documentation consolidation, shell scripting enhancements, security hardening, journald persistence, and packaging/version management (image tags/release notes).

January 2026 monthly summary for stackhpc-kayobe-config: Focused on stabilizing OpenStack networking by updating image tags for Nova and Neutron to include upstream networking-mlnx fixes and the latest versions, ensuring compatibility with rocky-9 and ubuntu-noble. Implemented two commits: rebuilding Nova/Neutron to apply the fixes and adding new tags aligned with a Rocky 9.7 rebase. This work improves networking stability, reduces deployment risk, and supports smoother upgrades across environments. Demonstrates end-to-end capability from tagging to validated image builds within Kayobe-config, reinforcing our ability to ship stable infrastructure components.

November 2025: Delivered a critical update to Prometheus alerting rules in stackhpc-kayobe-config to reflect the rename from redfish-exporter-seed to redfish-exporter, restoring visibility of failed scrapes and ensuring alerts trigger for the new job name. This involved adjusting the alert rules to align with the new job naming and referencing the commit that introduced the rename. The change improves monitoring reliability, reduces MTTR for redfish-exporter issues, and demonstrates strong cross-repo coordination and version-controlled config changes.

Month: 2025-06. Focused on delivering NVIDIA MIG support for the Slurm appliance, updating the build to accommodate MIG, integrating MIG configuration into Ansible roles, and expanding documentation to enable finer-grained GPU resource allocation for compute workloads. No critical bugs reported this month; MIG features unlock more efficient GPU utilization and scalable deployment for customers running multi-tenant workloads.

Monthly summary for 2025-05 focusing on stackhpc-kayobe-config work. Key deliverables include Redfish Exporter v2.x upgrade and configurable scrape intervals, improving server compatibility and observability. No major defects reported. Overall impact: improved monitoring reliability, greater flexibility for cadence, and better alignment with Dell/Lenovo server fleets.

March 2025: Delivered security-focused hardening and reliability improvements for the Ansible Slurm Appliance. Implemented default Lustre mount hardening and stabilized SSH drop-in management, reducing privilege escalation risk and enhancing configuration reliability across deployments.

February 2025 Monthly Summary for stackhpc/ansible-slurm-appliance focused on automation, cross-distro compatibility, and cluster reliability. Deliverables reduced manual toil, broadened OS support, and improved configuration flexibility to accelerate deployments and onboarding.

December 2024 monthly summary for stackhpc-kayobe-config focused on delivering a robust observability improvement to support HA for OpenStack routers, with corresponding documentation updates. The key feature delivered was a Prometheus alert to enforce exact-one active router behavior across ML2/OVS agents, including messaging refinements and release notes. No major bugs were reported as fixed this month; the work centered on feature delivery, code review improvements, and documentation.

November 2024 monthly performance summary for stackhpc-kayobe-config focused on reliability improvements in monitoring and hardening scripts. Delivered concrete features that enhance monitoring accuracy and security baseline, with clear guidance for revertability.

Monthly performance summary for 2024-10 focused on stackhpc/stackhpc-kayobe-config. Delivered a critical reliability improvement by updating the Ironic image tag to a newer version to resolve dnsmasq-related job failures. This change stabilized CI pipelines and reduced flaky deploy/test cycles in the Kayobe configuration.
