Jul 1, 2025July 2025: Stability and reliability improvements for sbcli with a focused fix to the --force-lvol-recreate flag parsing. The fix ensures the flag is treated as a boolean action with a default of false, increasing reliability during LVol recreation and reducing storage node restart failures.

Jun 1, 2025June 2025: Release readiness and stability hardening for sbcli. Key outcomes include the sbcli-alsh release with updated command name, version 18.0.74, and Docker image simplyblock/simplyblock:alsh, with environment variables and packaging updated (commit 5d014738f24e6c943c58f7837dd5bb0091f8a9ad). Also, fixed truncated core dumps by configuring systemd coredump (ProcessSizeMax) and bumping the software version (commit 6c4bdf0f31089ce2894506ebf8812ff0ab231a9d). These changes improve deployment consistency, reliability, and production readiness.

May 1, 2025May 2025 monthly highlights for simplyblock-io/sbcli: Delivered targeted improvements to distributed storage and versioning, with a fixed bug in job-manager ID aggregation. The work focused on clear business value: faster and more reliable first-write initialization in distributed storage, stable versioning for releases, and improved HA/job-manager reporting. Impact summary: - Improved initialization performance and consistency for distributed storage through a new CLI flag controlling full-page unmap during first write. - Maintained release discipline by updating SIMPLY_BLOCK_VERSION to 17.4.61 and refreshing environment version for alignment and compatibility. - Increased reliability in high-availability (HA) setups by correcting get_sorted_ha_jms output to include the proper job manager IDs. Notes on delivery: - All changes are small, targeted, and release-ready, with clear commit hygiene and traceability to the described features/bugs.
