摘要： Disclosed herein are an apparatus and method for converting a replication-based file into a parity-based file in an asymmetric clustering file system. The apparatus includes a reception unit, a control unit, a parity computation unit, and a chunk conversion unit. The reception unit receives a parity-based conversion request, information about the size of a stripe, and a list of new chunks from a metadata server. The control unit divides a replication chunk, selected from among a plurality of replication chunks corresponding to an original chunk of the replication-based file, into a plurality of data segments. The parity computation unit generates at least one parity segment by performing a parity operation on the plurality of data segments. The chunk conversion unit selects one of different data segments from the original chunk or one of the plurality of replication chunks, the different data segments having locations different from one another.

摘要： Provided are a file storage system, and a method for managing duplicate files in the file storage system. The file storage system that performs file duplication for error recovery includes a client for requesting generation of a duplicate file of a new file being stored, a metadata server for storing information associated with prestored duplicate files and determining whether a file that is identical to the new file is present among the prestored duplicate files, to limit a number of identical duplicate files to a preset number, and a data server comprising a file duplication unit and a storage unit for respectively performing file duplication and file storage under the control of the metadata server. Accordingly, file recovery can be performed while duplicate files in the system are minimized.

摘要： Provided are a method and a system for managing a file metadata, which are independent of a address change of a data server and movements of a disk by using a location of disk where data exists actually as a location information of a file data. The method for managing the file metadata includes determining whether the request of the metadata is valid, verifying information of a disk storing a file data corresponding to the metadata and a data server address in which the file data exists, and transmitting the verified address of the data server to the client. According to the method and the system for managing the file metadata, data services can be continuously provided without modifications of a file metadata even if the data server address is changed.
