Oct 1, 20252025-10 sbcli monthly summary: Delivered core SFAM QoS functionality (Alceml QoS Classes) to enable priority-based resource management and improved service quality. Strengthened QoS reliability with a coordinated group of fixes and migration to the RPC QoS weights API, including setting the QoS class index on activation. Enhanced resilience with an auto-restart feature for confirmed false RPC responses. Streamlined storage provisioning by merging LVol Geometry into main. Improved operational visibility with JC compression status retrieval and a new resume task runner. A broad suite of bug fixes across SFAM/SB subsystems (environment variable handling, image sourcing, timeout logging, and linter/quality fixes) stabilized the platform. Business impact: higher QoS predictability, faster incident recovery, simplified storage workflows, and better monitoring for operators.

Jun 1, 2025June 2025 SBCLI monthly summary: A strong month focused on stabilizing core orchestration, expanding storage capabilities, and improving deployment readiness. Delivered a set of high-impact bug fixes across the SFAM family that addressed core reliability gaps in SBCLI and cluster operations, while introducing automation and storage/infra enhancements that reduce manual toil and improve resilience. Key outcomes include automation of migration tasks on node online, first-write mapping for Alceml/Distrib bdevs, and multipathing support for cluster-internal nvmf connections. These efforts were complemented by device identification improvements, CLI usability fixes, and security/observability refinements, all contributing to a more robust production experience. Key achievements: - Stability improvements: Resolved SFAM-2071, SFAM-2072 (two commits), SFAM-2087, SFAM-2088, SFAM-2103, SFAM-2093, SFAM-2142, SFAM-2078, plus related health-check and CLI fixes. - Automation enhancement: Started migration tasks automatically when a node becomes online (commit 655ec68797c94a1a4dd1a727c583ded267c3f3f3). - Storage/infra enhancements: Enabled use_map_whole_page_on_1st_write for Alceml and Distrib bdevs; added multipathing support for cluster-internal nvmf connections; implemented identify device by PCI+namespace. - Observability and security: Fixed health check log generation/formatting; removed iptables drop rule; corrected SBCLI command name for TasksRunnerClusterStatus; improved node lifecycle robustness with leadership handling. - Deployment readiness: Performed version bumps; set default Ultra image repo; added --force to jm restart; fixed node-add interface alias naming and related release hygiene.
