摘要： Improved methods and systems for granular opportunistic locking mechanisms (oplocks) are provided for increasing file caching efficiency. Oplocks can be specified with a combination of three possible granular caching intentions: read, write, and/or handle. An oplock can be specified with an identifier that indicates a client/specific caller to avoid breaking the original oplock due to an incompatibility from other requests of the same client. An atomic oplock flag is added to create operations that allow callers to request an atomic open with an oplock with a given file.

摘要： In accordance with one or more aspects of the application-managed file versioning, a request to store a new version of a file is received from an application, the request having been generated by the application. A filename for the new version of the file is generated, derived from a standardized naming convention. The filename includes a first portion having at least a portion of a name of the file, and a second portion having data indicating that the new version of the file is a version of the file. A set of application programming interfaces (APIs) can be exposed that allow the application to manage file versions, such as creating a new version of a file, identifying one or more versions of the file, listing one or more versions of the file, and deleting one or more versions of the file.
摘要翻译：根据应用程序管理的文件版本控制的一个或多个方面，从应用程序接收到存储文件的新版本的请求，该请求已由应用程序产生。根据标准化命名约定生成文件的新版本的文件名。文件名包括具有文件名称的至少一部分的第一部分，以及具有指示该文件的新版本是该文件的版本的数据的第二部分。可以公开一组应用程序编程接口（API），允许应用程序管理文件版本，例如创建新版本的文件，识别文件的一个或多个版本，列出文件的一个或多个版本，以及删除文件的一个或多个版本。

摘要： Processing for file system volume error detection and processing for resultant error correction are separated to support system availability and user satisfaction. File system volumes for storing data structures are proactively scanned while the volumes remain online to search for errors or corruptions thereon. Found errors are scheduled to be corrected, i.e., spot corrected, dependent on the severity of the identified errors, error correction scheduling and/or at the determination of a file system administrator and/or user, to assist in maintaining minimal user and file system impact. When spot correction is initialized, one file system volume at a time is taken offline for correction. Spot correction verifies prior logged corruptions for the offline volume, and if independently verified, attempts to correct the prior noted corruptions. Volumes are retained offline only for the time necessary to verify and attempt to correct prior noted volume corruptions.

摘要： Perceived corruptions encountered on file system volumes, and which cannot be initially remedied online, are processed to verify whether they are true, existing volume data structure corruptions or, alternatively, false positives. Upon the verification of one or more of a volume's corruptions, error scanning is performed to check for, and attempt to remedy online, all the existing corruptions on the volume. Subsequent to error scanning processing, if one or more verified corruptions continue to exist on a file system volume, at file system boot up time spot corruption correction is performed to attempt to remedy the existing, verified corruptions on the volume. Spot corruption correction is performed to attempt to correct verified data structure corruptions on a volume of the file system while the volume is maintained offline for the time necessary to attempt to correct its prior identified corruptions.

摘要： Volumes of a file system remain online, and thus available for use, while being proactively error scanned for corruptions thereon. A snapshot of each volume being proactively error scanned is maintained for the volume during the proactive error scanner processing of the volume. Proactive error scanner processing only requires access to file system metadata to correctly process a volume for an identification of the corruptions thereon, and thus, a snapshot of the entire volume nerd not be generated nor maintained. The clusters of a volume that store file system metadata are identified and only these clusters are maintained in a scoped snapshot for the volume during proactive error scanning of the volume.

A snapshot of each volume being proactively error scanned is maintained for the volume during the proactive error scanner processing of the volume.
