Worked on the daos-stack/daos repository to enhance test reliability, CI stability, and telemetry scalability for distributed storage systems. Addressed flaky failures in erasure code rebuild tests by refining container lifecycle management and extended test timeouts to reduce CI-induced delays. Improved test infrastructure by optimizing SSH key handling and log management, and migrated performance-sensitive tests from virtual machines to hardware for faster feedback. Implemented Python-based automation for pool creation retries and introduced configuration management changes to expand telemetry pool capacity. Leveraged Python and YAML to deliver robust, traceable solutions that strengthened data integrity, observability, and overall test coverage in the codebase.

Apr 1, 2026Month: 2026-04 — Focused on strengthening telemetry data generation robustness and observability for daos-stack/daos. Delivered Telemetry Pool Capacity Enhancement by increasing the telemetry pool metrics capacity from 1G to 5G to support larger data generation and testing workloads. Implemented via commit e851c13dc795e95629f6346437a7470d9a68d3c7 (DAOS-18758). The related telemetry_pool_metrics.py test was updated to reflect the new capacity, aligning tests with the expanded pool size. No major bugs fixed this month; effort centered on capacity, test robustness, and traceability. Impact: more reliable telemetry collection under load, reduced risk of pool exhaustion during data generation, and clearer metrics configuration for future scaling. Technologies/skills demonstrated: configuration management, test tuning, telemetry instrumentation, and strong commit traceability.

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.

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.
