摘要： Provided is a storage system as follows. A server holds a management table that serves to manage a mount point of a file system. The management table stores a file system identifier that uniquely identifies the file system within the storage system, mount point information that indicates the mount point of the file system, and a management server identifier that indicates an identifier of the server that manages the file system. The contents stored in the management table of each server are the same. Upon reception of a request to obtain a file handle, each server returns the file handle requested to be obtained. The file handle indicates, uniquely within the storage system, the storage area on the disk subsystem in which the file relating to the request is stored.

摘要： A storage system capable of cutting back the resource while obtaining a WORM function. A controller (110) functions to: obtain, when a write request is made by a computer (300), information on one of logical devices that is a target of a write process, from a memory module (140); and inform, when the logical device is set to unwritable, a signal indicating that the logical device is set to unwritable, to the computer (300). An interface (200) functions to: reference meta-information held in a disk drive (130) to obtain a list of files that are not accessed for a predetermined period; secure a logical device; and cause the controller (110) to store, the files on the list of files and set the logical device that stores the files in a manner that makes information stored in the memory module (140) unwritable.
摘要翻译：一种能够在获得WORM功能的同时切割资源的存储系统。控制器（110）的功能是：从存储器模块（140）获取由计算机（300）写入请求时作为写入处理目标的逻辑设备之一的信息; 并且当所述逻辑设备被设置为不可写时，向所述计算机（300）通知指示所述逻辑设备被设置为不可写的信号。接口（200）用于：引用保持在磁盘驱动器（130）中的元信息，以获得在预定时间段内未访问的文件的列表; 安全逻辑设备; 并且使得所述控制器（110）将所述文件存储在所述文件列表上，并且以使得存储在所述存储器模块（140）中的信息不可写的方式设置存储所述文件的逻辑设备。

摘要： A computer system for managing log information, enabling correct comprehension of system logs for an identical resource before and after migration among plural nodes. A global ID, being unique in the system, is given to a resource (LU) migrated from one file share server to another. The global ID remains the same in the migration destination file share server after migration and log messages for the resource are obtained based on the global ID.

摘要： In a cluster type NAS, it is necessary to copy file data between disk devices of servers upon migration of a file system or a part of the file system. A server includes a control table for managing a file system or a part of the file system, and a mapping table for managing a relation between a logical device of a disk subsystem and a logical unit recognized by a server, and in response to an instruction to execute migration of the file system from a first server to a second server, the mapping table is referenced to send an instruction to update the relation between the logical device and the logical unit to the second server, and the second server newly recognizes a logical unit and updates a management server identifier of the control table.

摘要： A problem with a journaling file system is that the load on input/output processing executed between a server and a storage system is increased because a journal log is written when the file system is updated and updated data is written when flush processing is executed. In a system according to the present invention, a storage system that has received journal logs from a server uses updated data included in the journal logs to execute flush processing.
摘要翻译：日志文件系统的问题是在服务器和存储系统之间执行的输入/输出处理的负载会增加，因为在更新文件系统时写入日志日志，并且在执行刷新处理时更新数据。在根据本发明的系统中，从服务器接收日志日志的存储系统使用日志日志中包括的更新数据来执行冲洗处理。
