Ywang contributed to the daos-stack/daos repository by developing features focused on storage management and system programming using C and Go. Over two months, Ywang delivered md-on-SSD mode support for SMD Sync, enabling synchronization of data, metadata, and WAL blobs across multiple devices. The work included introducing a new SPDK initialization control path and updating device handling logic to improve end-to-end sync reliability. Additionally, Ywang implemented automated memory provisioning in the ddb utility, adding a workflow to configure tmpfs and VOS files for md-on-ssd mode. These changes reduced manual setup steps and improved maintainability across storage components.

Oct 1, 2025October 2025: Delivered memory provisioning support in the ddb utility for md-on-ssd mode, enabling automated memory environment setup via a new prov_mem workflow that configures tmpfs and VOS files. In addition, performed a targeted refactor: relocated the pool-target recreation logic from the mgmt module to the vos module and renamed it to vos_pool_recreate_tgts to support the new memory provisioning flow. This work is tracked under DAOS-17308 and lays the groundwork for more robust memory-backed storage automation. Overall impact: reduces manual steps, improves reliability in md-on-ssd configurations, and demonstrates strong cross-team collaboration between management, VOS, and ddb components.
