December 2025: Fixed a critical rebuild stability issue in Cray-HPE/csm-config by re-enabling the Target Port Group, which had been disabled and caused SQUASHFS errors during worker node rebuilds. This involved reverting a prior change (CASMTRIAGE-8171) that disabled the port group, restoring normal operation and preventing rebuild failures. Updated CHANGELOG.md and linked CASMTRIAGE-8848; CASMTRIAGE-8171 reopened for documentation. Impact: improved node reprovision reliability, reduced MTTR during maintenance, and preserved system integrity.

2025-11 monthly summary for Cray-HPE/csm-config: Delivered two core features that improve deployment automation and platform readiness, complemented by documentation and repository hygiene improvements. These efforts enhance consistency, reduce manual steps, and enable faster provisioning of Fabric Manager nodes and Slingshot installations across clusters.

August 2025 monthly summary for Cray-HPE/csm-config: Implemented automated Kyverno policy application and critical-services management, introducing a Python script to apply policies and restart critical services with idempotency checks. Added a static ConfigMap defining critical services/configs and ensured policy application only occurs when the ConfigMap is not present, reducing unnecessary updates. Reworked rolling restart (RR) handling by moving restart logic to a dedicated script and removing rollout restart from the main RR Ansible playbook, aligning with upgrade steps (CASM-5679). Deprecated and removed the Kyverno policy for Rack Resiliency Services (RRS), migrating policy handling to RRS, including removal of related Python script, static ConfigMap, and policy YAML, with corresponding changelog updates. All changes aimed at reducing downtime, preventing redundant actions, and simplifying policy management across clusters.

2025-07 monthly summary for Cray-HPE/csm-config focusing on delivering business value through stable configuration management and targeted bug fixes. Key accomplishment: robust handling of Rack Resiliency (RR) in the Ansible play when RR is disabled, preventing failures and improving operator UX. Work reduced deployment friction and improved reliability of site-init customizations.

Month: 2025-04 | Cray-HPE/csm-config focused on improving NMN DNS A-record robustness for iSCSI SBPS. Delivered a bug fix that ensures NMN DNS A records are created reliably, enhancing projection stability for iSCSI SBPS and reducing risk of projection failures due to missing DNS records. The work improves script reliability (sbps_dns_srv_records.sh) by improving curl failure detection and correct handling of CRLF in output, with a commit that ties to CASMPET-7443 and CASMPET-7444. This reduces potential downtime and supports smoother deployments.

November 2024 monthly summary for Cray-HPE/csm-config: Focused on stabilizing iSCSI target reconfiguration workflow and modernizing service management. Implemented a safety guard to prevent reconfiguring LIO targets when already set up, preventing SQUASHFS-related error reports. Migrated storage service management from legacy init scripts to systemd (systemctl) to improve reliability and maintainability. All changes are traceable to a single commit linked to the triage ticket CASMTRIAGE-7445.

Oct 2024 monthly summary: In Cray-HPE/csm-config and Cray-HPE/csm, delivered iSCSI reliability and security improvements focused on node personalization and provisioning. Implemented an iSCSI SBPS session visibility fix to ensure sessions are discovered across all worker nodes during node personalization bootprep, and hardened iSCSI CMN provisioning by removing the unused CMN iSCSI portal from LIO provisioning to prevent off-system access. Also applied management rollout fixes for iSCSI bootprep with proper authentication and included a csm-config version bump to reflect changes. These changes reduce operational incidents, strengthen security, and align config/runtime behavior for safer, multi-node deployments.
