Abstract: A distributed file system includes metadata servers and data servers. The metadata server includes a selecting unit to select a data server from the data servers, a chunk allocation requesting unit to request that the selected data server perform chunk allocation, a chunk list managing unit to insert a list of chunks transmitted from the data server into a chunk list pool and determine an arrangement method of the chunk list pool, and a chunk fetching unit to fetch available chunk information from the chunk list pool. The data server includes a receiving unit to receive request for chunk allocation from the metadata server, a chunk allocating unit to allocate chunks in response to the request for chunk allocation and write a list of chunks based on information about the allocated chunk, and a transmitting unit to transmit the list of chunks to the metadata server.

Abstract: A method and system that can completely delete garbage data in a distributed network system are provided. Because it is impossible to initially access a data server, data to delete is not deleted, and thus when a garbage file is generated, a generated garbage file can be completely deleted. In this case, by performing a deletion operation of a garbage file in a distributed data server unit, operation efficiency can be maximized.
Abstract translation: 提供了可以完全删除分布式网络系统中的垃圾数据的方法和系统。 由于不可能初始访问数据服务器，所以要删除的数据不会被删除，因此当生成垃圾文件时，可以完全删除生成的垃圾文件。 在这种情况下，通过在分散数据服务器单元中执行垃圾文件的删除操作，可以使操作效率最大化。

Abstract: A distributed storage server includes a plurality of data server devices and a plurality of metadata server devices. The metadata server devices store metadata associated with data which is distributively stored in the data server devices. A selected metadata server device checks whether a dangling directory occurs by performing a rename operation, based on information associated with a full path of a parent directory of a source and a full path of a parent directory of a target included in a request of the rename operation. When it is determined that the dangling directory does not occur, the selected metadata server device processes transactions directed to the metadata such that the rename operation is performed. The checking whether the dangling directory occurs is performed before a transaction period for processing the transactions.
