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： The file synchronization processing among sites which can reduce the response time is realized. By the CAS device creating a list of at least a part of the file groups which the first sub-computer system archived or backed up to the data center as an update list and transferring the update list to the second sub-computer system, the second sub-computer system determines whether the file is valid or not by using the update list (See Fig. 2).

摘要： The present invention provides a computer system capable of providing the latest statistics on a file system in real time. The computer system includes a memory having a program for executing statistics on a file system, and a controller for executing the program. When the file system is accessed, the controller compares first statistic information before access processing on the file system with second statistic information after the access processing; and if it is determined that any difference exists between the first statistic information and the second statistic information, the controller updates the statistic result of the file system based on the difference.

摘要： The client computer which transmits an access request specifying an object existing in the first file system and the second computer which accesses the second file system are connected to the first computer which accesses the first file system. The second file system includes a shared directory. A specific object which is an object complying with the path name including the name determined in accordance with the type of the second computer is stored in the shared directory. The controller mounts the shared directory to the first file system. The controller creates a link which comprises a name determined in accordance with a certain naming regulation independent of the type of the computer and corresponds to the specific object in the first file system.

摘要： A control unit of a storage system controller receives an access command to a first file specifying a first access position in the first file. A storage apparatus stores management information of the first file and management information of each of subfiles obtained by dividing the first file. The management information of the first file contains information associating a data position in the first file and management information of a subfile containning data at the data position. The management information of each of the subfiles contains information associating a data position in the corresponding subfile and a physical storage position. The control unit references the management information of the first file to identify the management information of the subfile containning the data at the first access position, and references the management information of the identified subfile to identify a physical storage position of the first access position.

摘要： The prior art information system could not migrate a file in a file sharing system provided by a file storage to a plurality of cloud storages having different forms of connection and different properties, and therefore, could not manage the files via a single Stub information. The present invention provides a data mover program in a file storage to select one or more migration destination cloud storages based on a migration policy, a connection information table of cloud storages and a property information table of cloud storages. Then, a Stub information of the migrated file is created, and an identification information of the file in the cloud storage is stored in a file information table. When access occurs from a client to a file storage, the data mover program downloads a file from the cloud storage stored in the file information table corresponding to the Stub information and provides the file to the client.

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.
摘要翻译：用于共享对象的计算机系统包括多个前端节点和用于提供由前端节点共享的命名空间的后端节点。任何一个前端节点的第一个前端节点管理由第一个前端节点管理的每个对象的本地锁定计数。本地锁计数是操作对包括其目录和子对象的对象所占用的锁数。每当从客户端接收到处理目标对象的请求时，如果父目录尚未被后端节点锁定，则前端节点请求后端节点锁定目标对象的父目录。前端节点向客户端发送接收到的请求的响应，而不管父目录是否已被后端节点解锁。如果父目录的本地锁定计数为零，则第一个前端节点请求后端节点解锁父目录。

摘要： It is provided a storage system including a storage device for storing data, and a controller for controlling data read/write in the storage device. The controller includes a processor for executing a program, and a memory for storing the program that is executed by the processor. The processor executes deduplication processing for converting a duplicate part of data that is stored in the storage device into shared data, and calculates a distributed capacity consumption, which represents a capacity of a storage area that is used by a user in the storage device, by using a size of the data prior to the deduplication processing and a count of pieces of data referring to the shared data that is referred to by this data.
