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.
