Jun 1, 2026June 2026 (sbcli) monthly summary: Delivered substantial reliability, feature progress, and performance tuning across the SBCLI surface. Focused on resilience during node restarts and failovers, improved health handling, and optimized workload paths. Major feature work includes JM shared_placement with upgrade-time migration support, a RAID 0+1 journal layout to reduce write amplification, and 3-node performance setup with tuned SPDK core allocation. Other notable deliverables include fixed distribution sizing (1 PiB per distrib), SPDK compression thread plumbing with co-location, and operator-facing improvements such as a UI-facing rename of the max-lvol flag. These edits, along with a broad set of reliability fixes and tests, improve deployment speed, data availability, and operational stability for customers. Top achievements highlight business value and technical depth: faster, safer cluster upgrades; reduced write amplification on journaling paths; improved restart and failover robustness; and enhanced visibility and test reliability across the stack.

Oct 1, 2025October 2025 SBCLI development focused on reliability, scalability, and maintainability for simplyblock-io/sbcli. Implemented RDMA/NVMe timeout tuning to improve performance on slower networks and added abort-on-timeout behavior for robust error handling. Introduced LVOL_CLUSTER_RATIO to size lvstore clusters as a ratio of the distributed page size, applying it across cluster activation, lvol statistics, and lvstore creation. Addressed constants usage and syntax through follow-up fixes to ensure correct conditional execution. Overall, these changes reduce timeouts, improve resilience in edge environments, and enable scalable configuration for larger deployments.
