摘要： In file de-duplication using hash value comparison, hash values of all target files must be calculated and actual data of all files must be read for hash value calculation, so that the processing time was long. The present invention provides a file storage system comprising a controller and a volume storing a plurality of files, the volume including a first directory storing a first file and a second file and a second directory storing a third file being created, wherein the controller migrates actual data of the second file to the third file, sets up a management information of the second file so that the third file is referred to when the second file is read, and if the sizes of actual data of the first file and the actual data of the third file are identical and the binaries of the actual data of the first file and the actual data of the third file are identical, sets up a management information of the first file to refer to the third file when reading the first file.

摘要： A file server is replaced efficiently. A computer system includes a first file server, a second file server, and a third file server. The first file server retains file data storage information which indicates, for each file, whether data of the relevant file is stored in a first storage device or not; and after a data input/output request from a client terminal is switched from the first file server to the third file server, the third file server selects either the first file server or the second file server as a data transfer request destination of a target file of the data input/output request from the client terminal, based on the file data storage information sent from the first file server.

摘要： A computer system for sharing objects comprises multiple front-end nodes and a back-end node for providing a namespace shared by the front-end nodes. A first front-end node that is any one of the front-end nodes manages local-lock counts for each of objects managed by the first front-end node. The local-lock count is the number of locks taken by operations to the objects including the directory and sub-objects thereof. Every time receiving a request for processing a target object from a client, the front-end node requests the back-end node to lock a parent directory of the target object if the parent directory has not been locked by the back-end node. The front-end node sends a response of the received request to the client regardless of whether or not the parent directory has been unlocked by the back-end node. If the local-lock count of the parent directory is zero, the first front-end node requests the back-end node to unlock the parent directory.

摘要： In the prior art clone creating technique of a file, a management table of a snapshot and the file was created when creating the clone file, so that a considerable amount of creation time for creating the clone file and storage capacity was required. In order to solve the problems of the prior art, the present invention provides a system wherein if a request to create a clone of a file is received, a differential file is created while inhibiting update of the file, and update data is written to the differential file. Further, when a first update request is received to the differential file after creating the differential file, a management table is created. According to the invention, a large amount of clone files can be created speedily.

摘要： It is provided a computer system, comprising a server and first and second storage systems. The first storage system stores deduplicated data sharing at least a part of data with other data, shared data shared by a plurality of pieces of the deduplicated data, and first type data representing a type of the stored data including the deduplicated data and the shared data. The deduplicated data is associated with the shared data by a pointer to the shared data, and includes differential data indicating a difference from the shared data. The server creates second type data representing a type of the data stored in the second storage system from the first type data. The second storage system stores the shared data associated with the deduplicate data at a reading position before a position at which the deduplicated data is read in sequential reading and stores the second type data.
