Abstract
Common block storage infrastructure techniques are described in which files are created through interaction with a file system to reserve extents in a volume on behalf of volume storage drivers, which may form a driver stack that resides logically on top of the volume. The files protect the reserved extents within the volume for use by the volume storage drivers, such as to store metadata related to operations performed by the drivers. When reserved extents are created, a location of the reserved extents is communicated through the driver stack to a corresponding volume storage driver. Volume storage drivers may also be configured to discover their corresponding reserved extents and communicate these to upper-level drivers and components. Accordingly, when a volume storage driver manipulates data in the volume, it may do so with awareness of the reserved extents of the other volume storage drivers.
