METHOD FOR AVOIDING CONFLICT AMONG METADATA OPERATION AND METADATA MANAGEMENT SYSTEM FOR PERFORMING THE SAME

摘要

PURPOSE: A metadata calculation collision avoidance method and a metadata managing system are provided to prevent damage to a file system even if the metadata calculations are simultaneously executed. CONSTITUTION: A directory metadata storing device(400) stores the metadata of a directory. A file metadata storing device(500) stores calculation intention information and the metadata of a file. When a metadata calculation process is requested, the directory metadata storing device calculates the requested metadata corresponding to first metadata calculation intention record completion information from the specific file metadata storing device. [Reference numerals] (300) Client device; (400) Directory metadata server; (410) Directory metadata storing unit; (500) File metadata server; (510) File metadata storing unit; (530) Metadata operation intension storing unit
