摘要： A method is used in managing logical views of directories. A directory logical view is created from a primary logical view. The primary logical view includes a set of storage objects. The directory logical view includes a subset of the set of storage objects. A root of the directory logical view indicates a file directory. The file directory includes the subset of the set of storage objects in a hierarchy. A mapping object is created for the directory logical view. The mapping object manages access to the subset of the set of storage objects. The mapping object for the directory logical view is a version of a mapping object for the primary logical view. Information is removed from the mapping object for the directory logical view. Information remained in the mapping object after removing the information is associated with the file directory.

摘要： A method is used in analyzing mapping objects of file systems. Each mapping object of a set of mapping objects of files of a file system is analyzed by iterating over the set of mapping objects. A file is associated with a first mapping object of the set of mapping objects and a snapshot copy of the file is associated with a second mapping object of the set of mapping objects. The second mapping object shares a subset of a set of storage objects associated with the first mapping object. Information for each storage object of the set of storage objects associated with each mapping object of the set of mapping objects is stored. Based on the stored information, each storage object of the set of storage objects associated with each mapping object of the set of mapping objects is processed.

摘要： A file system has files constructed of an inode for each file, indirect blocks, and allocation units of file system data blocks. Each of the allocation units has one of the file system data blocks or a plurality of the file system data blocks having contiguous file system block numbers. Each file in the file system has a respective allocation unit size attribute specifying an allocation unit size of each and every allocation unit in the file, and the files in the file system have allocation units of different allocation unit sizes. By using larger allocation units for larger files, there is a reduction in the number of indirect blocks in the files without a corresponding loss in performance, and a reduction in the time needed for the UNIX FSCK utility to check file system consistency.

摘要： A file server has a data compression facility and also a snapshot copy facility or a data de-duplication facility that shares data blocks among files. Compression of the file data on a file system block basis leads to a problem of partially used file system data blocks when the data blocks are shared among files. This problem is solved by partial block allocation so that file system data blocks are shared among files that do not share identical data. Block pointers in the file mapping metadata point to virtual blocks representing the compressed data blocks, and associated virtual block metadata identifies portions of file system data blocks that store the compressed data. For example, a portion of a file system data block is identified by a sector bitmap, and the virtual block metadata also includes a reference count to indicate sharing of a compressed data block among files.

摘要： A snapshot copy facility maintains information indicating ownership and sharing of child nodes in the hierarchy of a file between successive versions by delegating reference counts to the parent-child relationships between the nodes, as indicated by pointers in the parent nodes. When a child node becomes shared between a parent node of the production file and a parent node of a snapshot copy, the delegated reference count is split among the parent nodes. This method is compatible with a conventional data de-duplication facility, and avoids a need to update reference counts in metadata of child nodes of a shared intermediate node upon splitting the shared intermediate node when writing to a production file.
摘要翻译：快照复制工具通过将参考计数委托给父节点之间的父子关系来指示在连续版本之间的文件层次结构中的子节点的所有权和共享信息。当子节点在生产文件的父节点和快照副本的父节点之间共享时，委托引用计数在父节点之间拆分。该方法与常规的重复数据删除设备兼容，并且避免在写入生产文件时分割共享中间节点时更新共享中间节点的子节点的元数据中的引用计数。

摘要： Permitting multiple concurrent read operations upon a file system enhances small file performance. A respective instance of a thread routine stores the data from each file into a series of buffers for the file. Each instance is identified by a Process Identifier (PID) used for streaming the data from the buffers in the order in which the files are opened instead of the order in which the file data are returned by the read operations. In order to conserve buffer memory, read operations upon a file are suspended once a certain amount of data have been read from the file unless data from the file are being streamed from the buffers.
摘要翻译：允许对文件系统进行多个并发读取操作可以增强小型文件的性能。线程程序的相应实例将来自每个文件的数据存储到文件的一系列缓冲区中。每个实例由进程标识符（PID）标识，用于按照打开文件的顺序从缓冲区流式传输数据，而不是通过读取操作返回文件数据的顺序。为了节省缓冲存储器，一旦从文件读取了一定量的数据，除非文件中的数据被从缓冲器流传输，否则文件上的读取操作将被暂停。

摘要： This invention is a system and a method for recovering and repairing a logical volume in a data storage environment using a new architecture. The method of recovering a logical volume enables mounting of a file system by instantiating only a single slice under the sparse volume and instantiating rest of the slices provisioned under the sparse volume in background by a asynchronous recovery process or on-demand by the clients of the file system issuing an I/O on the slice volume. The method of repairing a logical volume provides the ability to regenerate the metadata required to reconstruct the corrupted volume.

摘要： Consistent updates are made automatically over a wide-area IP network, concurrently with read-only access to the remote copies. A replication control protocol (RCP) is layered over TCP/IP providing the capability for a remote site to replicate and rebroadcast blocks of the remote copy data to specified groups of destinations, as configured in a routing table. A volume multicast layer over RCP provides for multicasting to specified volume extents of the blocks. The blocks are copied at the logical level, so that it does not matter what physical structure is used for storing the remote copies. Save volumes buffer the remote copy data transmitted between the primary or secondary file system volume and the IP network, in order to ensure independence between the replication process, the IP transport method, and the primary file system being replicated.

摘要： A physical address extension feature maps multiple virtual memory spaces to an extended physical memory. Performance is enhanced by mapping chunks of both common and separate physical memory to each of the virtual memory spaces to provide efficient communication of parameters to and results from well-defined or well-contained software modules assigned to the chunks of separate physical memory. For example, the common physical memory stores stack allocation, per-processor data for communication between the virtual address spaces, BIOS, and device drivers. A first virtual memory space is directly mapped to a bottom region of physical memory containing buffer cache and page tables. In a file server, for example, one of the virtual memory spaces contains an inode cache, another contains a domain name lookup cache, and still another contains a block map for snapshot copies.
