    • A file storage performs control to create a virtual parent file having an identifier capable of uniquely identifying a parent file among storage systems and volumes, and to acquire block layout information of the parent file using said identifier. The file storage creates a virtual parent file in the volume in which the clone file is created, and sets the file as a virtual parent file of the clone file so as to enable creation of a clone file of a parent file that exists in a different volume or a different storage system. Moreover, by combining creating the virtual parent file and switching the identifier of the parent file which is pointed by the virtual parent file, migration of clone files and parent files astride storage systems and volumes is enabled.
    • 文件存储器执行控制以创建具有能够在存储系统和卷之间唯一地标识父文件的标识符的虚拟父文件,并使用所述标识符获取父文件的块布局信息。 文件存储在创建克隆文件的卷中创建虚拟父文件,并将该文件设置为克隆文件的虚拟父文件,以便能够创建存在于不同的父文件中的父文件的克隆文件 卷或不同的存储系统。 此外,通过组合创建虚拟父文件并切换虚拟父文件指向的父文件的标识符,启用跨越存储系统和卷的克隆文件和父文件的迁移。

    • A file server including: a first interface coupled to a client computer which manages a client side user identifier used by the client computer to identify a client computer user; a second interface coupled to a first storage storing first file system data and a first file system side user identifier used by the first file system to identify the client computer user, and a second storage storing second file system data and a second file system side user identifier used by the second file system to identify the client computer user; a processor which receives a client computer's first access request to the first file system, obtains a first file system identifier which identifies the first file system and the first file system side user identifier, and translates the first file system side user identifier to a first client side user identifier using the first file system identifier.

    • Upon integration of a file system, user identifier recorded in a storage as management data is translated. A file server connected to a storage storing the data of a file system therein has a file system operation unit for managing the file system, a file server operation unit for receiving the access request to the file, and a user identifier translation unit for carrying out translation between first user identifier, which is used by the client and second user identifier, which is recorded in the storage as management data of the file system. Receiving the access request to the file from the client, the user identifier translation unit translates the second user identifier included in the management data of the file that is an access target of the access request into the first user identifier, and the file server operation unit transmits the management data to the client.
    • 在文件系统的集成时,将存储在存储器中的用户标识符作为管理数据进行翻译。 连接到存储文件系统的数据的存储器的文件服务器具有用于管理文件系统的文件系统操作单元,用于接收对该文件的访问请求的文件服务器操作单元和用于执行文件系统的用户标识符转换单元 作为文件系统的管理数据记录在存储器中的由客户端使用的第一用户标识符和第二用户标识符之间的转换。 从客户端接收对文件的访问请求,用户标识符转换单元将包括在作为访问请求的访问目标的文件的管理数据中的第二用户标识符转换为第一用户标识符,以及文件服务器操作单元 将管理数据发送给客户端。
