摘要： Each time the file access request is received, it is discriminated whether there is an ACL which corresponds with the file system of the type following the switching in the file designated by the file access request. In cases where the judgment result is that there is no such ACL, an ACL which corresponds with the file system of the type following the switching is generated on the basis of an ACL which corresponds with the file system of the type prior to the switching which is associated with the designated file, and the ACL thus generated is used to control access in accordance with the received file access request.
摘要翻译：每当接收到文件访问请求时，区分是否存在与由文件访问请求指定的文件切换之后的类型的文件系统相对应的ACL。在判断结果是不存在这样的ACL的情况下，根据与切换前的类型的文件系统对应的ACL来生成与切换后的类型的文件系统对应的ACL，与指定的文件相关联，并且由此生成的ACL被用于根据接收到的文件访问请求来控制访问。

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： Regarding a method for migrating a file system by copying a file from a migration source to a migration destination and deleting the file at the migration source, a retention of a file in a page (allocation unit of a thin provisioning function) is either suppressed or solved, and two methods are proposed for solving the problems and for enabling migration of a file system in which the increase of utilization of storage capacity is suppressed, wherein one method changes the location of a file prior to performing copying so that the file to be copied next is located in the same page, and another method creates a reverse index table to recognize which block is used by files, thereby enabling to specify the file remaining within a page and copy the same by referring to this reverse index table.

摘要： There has never been disclosed a method of executing migration on a fine-grained basis than a file system basis in a manner that is transparent to clients in a storage system with a plurality of servers to which a global name space is applied. In a storage system with a plurality of servers and a disk subsystem, which is coupled to the plurality of servers, a file system in the disk subsystem is assigned a first identifier, which is unique throughout the storage system, at least one of directories contained in the file system is assigned a second identifier, which is unique throughout the storage system, and a file contained in the file system is assigned a third identifier, which is unique throughout the file system. The server identifies a file below the directory that has the second identifier by the second identifier and by the third identifier.

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.
