Worked on enhancing storage coalescing test reliability in the xcp-ng/xcp-ng-tests repository, focusing on improving determinism and reducing flakiness in continuous integration environments. Addressed issues by ensuring the xxd utility was consistently available on all test hosts and by extending operation timeouts for coalesce processes. Introduced a Python-based fixture to automatically restart the toolstack after yum state changes, which helped maintain consistent sm-list outputs across multiple hosts. Leveraged skills in DevOps, system administration, and test automation to streamline storage resource enable and disable cycles, resulting in cleaner, more predictable test outcomes and improved fixture management for xcp-ng storage workflows.
