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： Disclosed herein are an apparatus and method for enabling clients to participate in data storage in a distributed file system. The client device of a distributed file system according to the present invention includes a storage determination unit and a file reading unit. The storage determination unit determines whether first metadata information, including a global generation number of the chunk corresponding to a file to be read, has already been stored in the local storage. The file reading unit performs a read operation on the file using local data corresponding to the first metadata information if, as a result of the determination, it is determined that the first metadata information has already been stored.
