62 Commits • 7 Features
Jun 1, 2026June 2026: sbcli delivered notable feature improvements, stability hardening, and operational tooling across storage provisioning, backup, and migration workflows. Key outcomes include a speed-optimized LVol cloning path, clearer backup state tracking, and hardened activation/error handling, alongside expanded validation and CLI capabilities. Migration and snapshot flows were stabilized with safer node_id access, preexisting-snapshot handling, and fallback creation paths. Infra and observability improvements were achieved through enhanced logging, Docker/config updates, and extended RPCs for lvol/hublvol operations. Collectively these changes reduce provisioning time, minimize outages during migrations, and improve data consistency, recoverability, and overall operational efficiency.

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.
