  • Metadata compaction in a distributed storage system
    Patent number: 11232070
    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.
    Type: Grant

  • Duplicate request checking for file system interfaces
    Patent number: 11093446
    Abstract: Example distributed storage systems, file system interfaces, and methods provide duplicate request checking. A file interface manages a plurality of file data requests from client systems using a file system protocol. A metadata store acts as a cross-reference between file data references and storage data references. A request data store in the metadata store includes request entries with transaction identifiers for corresponding file data requests. A duplicate checker searches the request data store and excludes incoming file data requests when it finds a matching request entry.
