Abstract
Systems and methods for metadata compaction in a distributed storage system with a file system interface are described. A file system interface and an object storage system interface use a metadata index for mapping object identifiers from the object storage system to location identifiers for the file system. When the metadata index includes a number of entries for continuous data blocks with overlapping intervals, a defragmentation operation may generate a defragmented entry for a defragmentation interval overlapping the overlapping data blocks.
