Abstract
A system and method reclaims unused storage space from a data container, such as a logical unit number (LUN) of a storage system. In particular, a novel technique is provided that allows a storage system to reclaim storage space not used by a client file system for which the storage system maintains storage, without requiring assistance from the client file system to determine storage usage. In other words, storage system may independently reclaim storage space not used by the client file system, without that file system's intervention.
