摘要： A method for reducing duplicate data of an active file system, where the data is stored on a storage device of a storage system, is disclosed. A persistent image of the active file system is generated at a first point in time. At a later time, a sequence of steps to compare the active file system with the persistent image is initiated. Then, if a block of data of the active file system is identical to the data in the persistent image, the active file system is directed to refer to the persistent image for data of the file. Alternatively, if the block of data of the active file system is not identical to the data in the persistent image, the active file system is directed to refer to the data of the active file system. A file folding command may be issued to start the comparison.

摘要： The present invention relates to a system for restoring a file from a snapshot, where a version of the file exists in both an active file system and the snapshot. A twin inode is created in the active file system and comparisons are made between block pointers of the twin inode and the snapshot. If there is a match, the block pointer of the twin inode is moved to the active file system. If there is not a match, a determination is made whether the snapshot block pointer exists in the active file system. If the snapshot block pointer does not exist in the active file system, it is copied to the active file system. If it does exist, then the actual data block pointed to by the snapshot block pointer is copied to the active file system. In this way, a file may be restored without the need to always copy every individual data block or inode from the snapshot.
摘要翻译：本发明涉及一种用于从快照恢复文件的系统，其中文件的版本存在于活动文件系统和快照中。在活动文件系统中创建一个双引号，并且在双引号和快照的块指针之间进行比较。如果有匹配，则双胞胎inode的块指针将被移动到活动文件系统。如果不匹配，则确定快照块指针是否存在于活动文件系统中。如果活动文件系统中不存在快照块指针，则将其复制到活动文件系统。如果存在，则将快照块指针指向的实际数据块复制到活动文件系统。以这种方式，可以恢复文件，而不需要总是从快照中复制每个单独的数据块或inode。

摘要： A method and system for reliably performing extra-long operations in a reliable state-full system (such as a file system). The file system includes a separate portion of the file system reserved for files having extra-long operations in progress, including file deletion and file truncation. This separate portion of the file system is called the zombie file space; it includes a separate name space from the regular (“live”) file system that is accessible to users, and is maintained as part of the file system when recording a consistency point.

摘要： File system is capable of performing long operations, such as deletions and truncations of long files, in a deterministic and atomic manner with regard to its recorded consistency points. The system includes both live filespace accessible to users, and user-inaccessible zombie filespace. In representative embodiments, the system includes a file deletion manager and a truncation manager capable of operating on files in the zombie filespace. Changes to the zombie filespace can be recorded in persistent memory. After a power failure or a similar event, the system can use the recorded changes to replay operations on the files in the zombie filespace, facilitating recovery. Zombie space can be sized dynamically, enabling the deletion manager to request enlargement of the zombie filespace. In some embodiments, files are transferred to the zombie filespace before links to the files' blocks in the live filespace are broken, and before performing operations on the files.
摘要翻译：文件系统能够以确定性和原子的方式对其记录的一致性点执行长操作，例如长文件的删除和截断。该系统包括用户可访问的实时文件空间和用户无法访问的僵尸文件空间。在代表性实施例中，系统包括能够对僵尸文件空间中的文件进行操作的文件删除管理器和截断管理器。对僵尸文件空间的更改可以记录在持久性内存中。在电源故障或类似的事件之后，系统可以使用记录的更改来重放僵尸文件空间中的文件的操作，从而有助于恢复。僵尸空间可以动态调整大小，使删除管理器能够请求放大僵尸文件空间。在一些实施例中，在到文件空间中的文件块的链接被破坏之前以及在对文件执行操作之前，将文件传送到僵尸文件空间。

摘要： A system and method for conforming a metadata file associated with qtree of a storage system to a version used by a file system kernel of the storage system, where the version indicates a format of the metadata file. The metadata file stores state information with respect to each qtree, and may be located outside of the qtree structure. Major and minor versions are compared with latest known major and minor versions associated with the file system kernel. In response to such comparisons, the metadata file may be updated to a newer version, rolled back to an older version, and/or the system may enter a corrective state where further operations are performed.

摘要： A heat exchange system and method of use are provided. The system may include an inlet, an outlet, and a plurality of tubes in communication with the inlet and the outlet. The plurality of tubes may include a first tube located adjacent to a second tube. A first drain conduit may be in communication with the first tube at a location between the inlet and the outlet, and a second drain conduit may be in communication with the second tube at a location between the inlet and the outlet, such that the first and second drain conduits are operable to drain fluid from the plurality of tubes. The method may include supplying fluid to the inlet, flowing fluid through the plurality of tubes, returning fluid to the outlet, and removing a portion of the fluid from the plurality of tubes via a drainage manifold that is in fluid communication with the plurality of tubes at a location between the inlet and outlet.

摘要： Methods and systems for communicating information between computer networks in which the information to be communicated is required at one location (e.g. for processing) but only available at another location. The information may be absent deliberately (for privacy reasons) or may simply be unavailable as an artifact of the computer network(s) involved. The required information, such as the internal client IP address, is inserted into the outgoing network communication in a manner that does not to materially affect the normal transit or utility of the network communication (e.g. as custom headers). The information is preferably inserted in an encrypted form, so that it may pass over a public network and be invulnerable to unauthorised scrutiny.

摘要： Embodiments described herein adapt static-image and clone technology to provide a simulated dynamic image to an application requesting a dynamic image. A storage system is configured to backup its file system by taking a first static image of the file system at a point in time. A clone of the first image may then be produced, the clone containing any subsequent changes to the file system and a reference pointer to the first image. A second static image of the clone is then produced. An application may request, from the storage system, an image of the file system. In response, the second static image may be presented to the application as a simulated dynamic image.

摘要： NMR logging in a wellbore is used to monitor an oil reservoir during oil recovery by miscible displacement. Diffusivity distributions found by NMR logging indicate whether one or two phases are present and composition of residual oil. Operation of the oil recovery procedure may be maintained or modified in response to monitoring of the reservoir.
