Abstract: 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.

Abstract: 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.

Abstract translation: 本文档描述了影响虚拟磁盘的技术。 在示例性配置中，虚拟磁盘文件可以与充当日志和检查点记录的日志相关联。 当生成日志条目时，可以存储标识尾部的信息。 在虚拟磁盘文件不正确关闭的情况下，即发生崩​​溃或电源故障的情况下，可以使用此信息来发现要重播的日志条目序列。 除了上述之外，在权利要求书，详细描述和附图中描述了其它技术。

Abstract: 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.

Abstract translation: 本文档描述了存储虚拟磁盘有效负载数据的技术。 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。 在某些情况下，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。

Abstract: 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.
