    Description

      This document presents the design and implementation for hole-aware read optimization in the Lustre file system. The design enables clients to cache file hole information locally and serve zero-filled pages for hole regions without long client I/O path, network round-trips and bulk data transfer, significantly improving performance for sparse file read operations while maintaining data consistency through Lustre's existing DLM (Distributed Lock Manager) infrastructure.
