摘要： A file system maintains information about files in data areas called dinodes. Dinodes are grouped into dinode pages wherein each dinode page includes information about one or more dinodes. Each dinode may use extended attribute data. Each dinode page having at least one dinode that uses extended attribute data has a corresponding dinodex page. The dinodex page includes extended attribute information about any of the dinodes in the dinode page that use extended attribute information. The page is divided into areas, each area corresponding to a different dinode. A lock is established for each dinode page so that any dinode adding or deleting its extended attribute address obtains the lock before proceeding to maintain cooperation between the dinodes. In this manner multiple extended attribute areas are prevented from corresponding with a particular dinode page and unused extended attribute pages are removed without unduly impacting system performance.
摘要翻译：文件系统维护有关名为dinodes的数据区域中的文件的信息。 Dinode被分组成dinode页面，其中每个dinode页面包括关于一个或多个dinode的信息。每个dinode可以使用扩展属性数据。具有至少一个使用扩展属性数据的dinode的每个dinode页面具有相应的dinodex页面。 dinodex页面包含有关dinode页面中使用扩展属性信息的任何dinode的扩展属性信息。页面分为区域，每个区域对应于不同的dinode。为每个dinode页面建立锁定，以便在继续维持dinode之间的协作之前，任何添加或删除其扩展属性地址的dinode都将获得锁定。以这种方式，防止与特定的dinode页面对应的多个扩展属性区域，并且移除未使用的扩展属性页面而不会不适当地影响系统性能。

摘要： A system and method for releasing storage space at the beginning of a byte stream while maintaining sequential byte stream semantics is provided. A ghost offset is initialized when a file is instantiated or opened. When information is deleted at the beginning of the sequential byte stream, the ghost offset is incremented in the amount of the number of bytes being deleted. The ghost offset continues to increment while the file is opened and information is being deleted at the beginning of the data stream. The virtual offset is the ghost offset added to the real offset of a particular entry in the data stream which maintains sequential byte stream semantics. When the file is closed, storage space is released in the amount of the ghost offset. Applications are provided with virtual offsets corresponding to data locations which are converted to real offsets for accessing data in the data stream.
摘要翻译：提供一种用于在保持顺序字节流语义的同时在字节流的开头释放存储空间的系统和方法。当文件被实例化或打开时，将初始化一个ghost offset。当在顺序字节流的开头删除信息时，ghost偏移量将以被删除的字节数量的量递增。当文件打开并且在数据流的开始处正在删除信息时，ghost偏移量继续增加。虚拟偏移量是添加到数据流中的特定条目的实际偏移量中的重影偏移量，其保持顺序字节流语义。当文件关闭时，存储空间以ghost偏移量的量释放。应用程序具有对应于数据位置的虚拟偏移量，这些数据位置被转换为用于访问数据流中的数据的实际偏移量。

摘要： Embodiments include a method comprising transmitting from a node of a plurality of nodes within a clustered file system provides concurrent file I/O access for files, to write access a region of a file. The method includes receiving an authorization to write access the region without a lock to preclude access of the region by other nodes, if at least one physical section in a machine-readable medium has been allocated for storage of the region by the server. The method includes receiving the authorization to write access the region with the lock to preclude access of the region by the other nodes, if the at least one physical section in the machine-readable medium has not been allocated for storage of the region by the server. Responsive to receiving the authorization to write access, metadata is transmitted for storage into the at least one physical section in the machine-readable medium.

摘要： A system for managing a file system. In response to a user selecting an image of the file system to perform a rollback operation, each data block in the file system that is owned by the image is searched for. Then, it is determined whether a data block owned by the image is marked in a first map and a second map. In response to determining that the data block owned by the image is marked in the first map and the second map, the data block is marked in a third map. In response to determining that the data block owned by the image is marked in the third map, a new data block is allocated in the file system. Subsequently, data from the data block owned by the image is copied to the new data block in the file system prior to performing the rollback operation to avoid a collision that causes data corruption.

摘要： An apparatus, system, and method are disclosed for differential data backup using snapshot on-write data. A snapshot module maintains an on-write data structure that captures a point-in-time or temporal instance of a data set by tracking modifications to data blocks of a data set. A backup module copies the data set to a backup data storage device as a full data set backup. In addition, the backup module copies each modified data block indicated by the on-write data structure and a differential time stamp to the backup data storage device as a differential data set backup. The full data set backup and one or more differential data set backups form a plurality of temporal instances of the data set. In one embodiment, a restore module recovers a selected instance of the data set responsive to receiving a restore command by copying the full data set backup to a target data storage device. In addition, the restore module may copy the differential data set backup to the target data storage device if the differential time stamp corresponds to a target time value.

摘要： A method, apparatus, and computer instructions for managing data in a file system in a data processing system. A request to modify a data block in the file system is detected during file system recovery time. In response to detecting the request, metadata is written to describe the data block into a snapshot image. The data is copied for the data block in the file system to the snapshot image. The data block is modified in the file system after the data is copied into the snapshot image. The snapshot image may be used to return the file system to a state prior to modifying the data block in the file system.

摘要： The present invention provides a computer implemented method for truncating a file in a file system. The file system receives a request to truncate a file to a target size, the file having a first inode. The file system creates a second inode to a transient directory, wherein the second inode holds a plurality of in-progress entries. The file system sets a target size in the first inode. The file system writes a truncate entry to a journal, the truncate entry comprising a predetermined size. The file system truncates the file by up to the predetermined size. The file system determines that the file is above the target size. Responsive to a determination that the file is above the target size, the file system repeats the truncating step and the determining step. Responsive to a determination that the file is not above the target size, the file system applies the in-progress entries from the transient directory.
