    • A file level striping method adds an option for indicating whether or not to support file level striping to a file creation interface in a file system, extends an inode structure to include a last disk ID field, initializes the last disk ID when the file is created in the file system, allocates a physical block based on the last disk ID when the physical block allocation is requested at the time of file I/O request in the file system, and modifies the last disk ID value to reflect the physical block allocation made by a volume manager. An apparatus using the file level striping method includes a number of disks for storing information actually, the volume manager for logically grouping a number of disks and a file system for creating files on said logical volume and performing I/O operations.

    • Disclosed is a coherence preservation method of duplicated data in RAID subsystem. The method comprises the steps of: if a read operation is requested by the RAID subsystem, selecting an arbitrary target disk among disks having duplicated data, and implementing the read operation on the selected disk; implementing a read error handling to determine whether an error occurs in the disks selected upon the read operation, and if the error occurs in the read operation of the selected target disk, repeating the read error handling until the read operation of the data succeeds by circulating the remaining metering-treated disks in turns; after the read error handling, if the read operation on the remaining disk in all succeeds, completing the read error handling, and if the read operation on the remaining disk in all fails, returning the error to the disk, and completing the read error handling; if a write operation is requested by the RAID subsystem, implementing the write operation on the disks having duplicated data; after implementing the write operation, if a temporary error occurs in the duplicated data, implementing a temporary error handling to maintain the data coherence in the disks having the duplicated data and to recover the temporary error; and after implementing the write operation, if a permanent error occurs in the duplicated data, implementing a permanent error handling to maintain the data coherence in the disks having the duplicated data and to recover the permanent error.
    • 披露了RAID子系统中重复数据的一致性保存方法。 该方法包括以下步骤:如果RAID子系统要求读取操作,则在具有复制数据的盘中选择任意的目标盘,并在所选择的盘上实现读取操作; 执行读取错误处理以确定在读取操作中选择的磁盘中是否发生错误,并且如果在所选择的目标盘的读取操作中发生错误,则重复读取错误处理,直到数据的读取操作成功通过循环 剩余的计量处理盘轮流; 在读取错误处理之后,如果剩余磁盘上的读取操作全部成功,完成读取错误处理,并且如果所有剩余磁盘上的读取操作全部失败,则将错误返回到磁盘,并完成读取错误处理 ; 如果RAID子系统要求写操作,则在具有重复数据的磁盘上实现写操作; 在执行写入操作之后,如果在复制数据中发生临时错误,则执行临时错误处理以维持具有复制数据的磁盘中的数据一致性并恢复临时错误; 并且在实施写操作之后,如果在复制数据中发生永久性错误,则实施永久性错误处理以维持具有复制数据的盘中的数据一致性并恢复永久错误。
