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.
摘要翻译：提供了改进的粒度机会锁定机制（oplock）的方法和系统，用于提高文件缓存效率。可以通过三种可能的粒度缓存意图的组合来指定Oplock：读取，写入和/或处理。可以使用指示客户端/特定呼叫者的标识符来指定oplock，以避免由于与同一客户端的其他请求的不兼容而破坏原始oplock。添加一个原子oplock标志来创建允许调用者使用给定文件的oplock请求原子打开的操作。

摘要： A delete notification can be received at a storage stack filter in a storage stack. It can be determined whether the delete notification applies to an entire storage device. If the delete notification does not apply to the entire storage device, a first set of actions can be taken with the storage stack filter in response to the delete notification. If the delete notification does apply to the entire storage device, a second set of actions can be taken with the storage stack filter in response to the delete notification.
摘要翻译：可以在存储堆栈中的存储堆栈过滤器处接收删除通知。可以确定删除通知是否适用于整个存储设备。如果删除通知不适用于整个存储设备，则响应于删除通知，可以与存储堆栈过滤器进行第一组动作。如果删除通知适用于整个存储设备，则响应于删除通知，可以与存储堆栈过滤器进行第二组动作。

摘要： A processing device and a machine-implemented method may be provided for tracking file system dependencies with respect to a volume residing on a storage device and guest volumes residing on virtual storage devices nested within the volume. A shim driver may receive an indication of a virtual storage device being surfaced and may parse contents to surface partitions and volumes contained within the virtual storage device to a system. The shim driver may open a guest volume nested within a host volume and may send a register request, regarding the guest volume, to a virtual disk mini-filter associated with the host volume. The virtual disk mini-filter may save information regarding a relationship between the host volume and the guest volume. The saved information may be used to prevent file system corruption when the host volume is dismounted or unexpectedly removed.
摘要翻译：可以提供处理设备和机器实现的方法来跟踪驻留在存储设备上的卷的文件系统依赖性，以及驻留在嵌套在卷内的虚拟存储设备上的客户机。垫片驱动器可以接收正在浮出的虚拟存储设备的指示，并且可以将包含在虚拟存储设备内的表面分区和卷的内容解析为系统。垫片驱动程序可以打开嵌套在主机卷内的客户机卷，并且可以将关于客户机卷的注册请求发送到与主机卷相关联的虚拟磁盘小型过滤器。虚拟磁盘小型过滤器可以保存关于主机卷和客户卷之间的关系的信息。保存的信息可能用于在主机卷卸载或意外删除时防止文件系统损坏。

摘要： This document describes techniques for storing virtual disk payload data. In an exemplary configuration, each virtual disk extent can be associated with state information that indicates whether the virtual disk extent is described by a virtual disk file. Under certain conditions the space used to describe a virtual disk extent can be reclaimed and state information can be used to determine how read and/or write operations directed to the virtual disk extent are handled. In addition to the foregoing, other techniques are described in the claims, figures, and detailed description of this document.
摘要翻译：本文档描述了存储虚拟磁盘有效载荷数据的技术。在示例性配置中，每个虚拟磁盘盘区可以与指示虚拟磁盘盘区是否被虚拟磁盘文件描述的状态信息相关联。在某些条件下，可以回收用于描述虚拟磁盘盘区的空间，并且可以使用状态信息来确定如何处理指向虚拟磁盘盘区的读取和/或写入操作。除了上述之外，在本文的权利要求，附图和详细描述中描述了其它技术。

摘要： In an exemplary embodiment, a virtual disk file can be assigned an identifier and a virtual disk files that is dependent on the virtual disk file can include a copy of the identifier. In the instance that the virtual disk file is opened and data is modified that causes the contents of a virtual disk extent to change the identifier can be changed. If the virtual disk file and the dependent virtual disk file are used to instantiate a virtual disk the difference between identifiers can be detected, which is indicative of the fact that the virtual disk may be corrupted. Other techniques are described in the detailed description, claims, and figures that form a part of this document.

摘要： A method and system for supporting a concurrent recordation of a change in a data file by a server while allowing an application to continue writing changes to a data file. In response to a change in a data file, a near-instantaneous version of the file is created. Metadata reflecting the change to the data file are synchronized with a version of the file in cache and recorded in persistent storage. During the process of recording metadata changes to the file, subsequent changes to the data file may continue, and metadata reflecting the changes may be recorded in a subsequent near-instantaneous version of the file which may also be synchronized with a version of the metadata in persistent storage.

摘要： This document describes techniques for effecting a virtual disk. In an exemplary configuration, a virtual disk file can be associated with a log that acts as both a log and a check point record. When a log entry is generated, information that identifies the tail can be stored therein. This information can be used in the event that virtual disk file is improperly closed, i.e., a crash or power failure occurs, to discover a sequence of log entries to replay. In addition to the foregoing, other techniques are described in the claims, detailed description, and figures.
