Ding-Hwa Ho enhanced the daos-stack/daos repository by focusing on test reliability, CI stability, and data integrity for storage system workflows. Over four months, Ding-Hwa implemented Python-based automation to stabilize erasure code rebuild tests, introduced retry mechanisms for pool creation, and migrated performance-sensitive tests from virtual machines to hardware to improve throughput. By refining CI/CD pipelines and addressing SSH configuration issues, Ding-Hwa reduced flaky failures and shortened feedback cycles. The work included YAML-driven configuration management and robust test tagging, ensuring that destructive operations waited for rebuild completion, thereby strengthening data protection and improving the maintainability of the DAOS testing framework.

Mar 1, 2026March 2026: Delivered a critical data integrity improvement for DAOS pool lifecycle by implementing a wait-for-rebuild mechanism before pool destruction and enhancing test clarity with a rebuild tag. This change reduces risk of data loss during destructive operations and strengthens test coverage for pool management.

Oct 1, 2025Concise monthly summary for Oct 2025 for daos-stack/daos: Key improvements to CI stability and test reliability through rebuild test stability improvements, enhanced test infrastructure logging, and an SSH key path fix. Implemented longer timeouts for DAOS rebuild tests to reduce CI timeouts and flaky failures; improved test infrastructure logging for better visibility and reproducibility; resolved SSH key path handling for dfuse sparse tests. Resulted in more reliable test feedback, fewer CI-induced delays, and faster PR validation.

Jul 1, 2025July 2025 summary for daos-stack/daos: Stabilized test reliability around erasure code online rebuild (EC-OLB) scenarios by preventing post-test container destruction in mdtest, addressing timeouts and improving CI stability. Implemented the DAOS-17770 fix to stop destroying containers during the mdtest phase of test_ec_online_rebuild_mdtest (commit 0a4dcc8604814941813ac6587a99f027a1f60b80), reducing flaky failures and shortening test cycles. This work enables faster, more deterministic validation of EC rebuild behavior and improves developer productivity.
