DATA UPDATE METHOD AND DEVICE IN DISTRIBUTED FILE SYSTEM

摘要

A data update method and device in a distributed file system. The method comprises: acquiring update data, writing the update data to a tail portion of a current data node, and updating corresponding index information in the data node (S402); and writing the update data to a tail portion of a check node, and updating corresponding index information in the check node (S404). The present invention achieves the effects of high performance, less computational resource occupation and data consistency for a data update process in a distributed file system.
