Abstract
Techniques for copying forward live data within storage regions used by a file system to new storage regions are provided. Storage regions refer to ranges of persistent storage within a storage medium. One or more live-clump-identifying workers identify a set of live-clump-references. The live-clump references are references to live clumps that belong to live objects. Live clumps represent a unit of data. After identifying the set of live-clump-references, one or more container-identifying workers identify a set of storage regions that contain clumps that correspond to the set of live-clump references. After identifying the set of storage regions corresponding to the set of live-clump-references, a plurality of copy-forward task workers perform copy-forward operations on the set of storage regions to copy live data to new storage regions.
