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.

Abstract translation: 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。
