Abstract
A technique for supporting snapshots and provisioning in a NAS (network attached storage) cluster includes implementing a file system built upon a virtual disk realized in a virtualization platform, the virtual disk itself built upon a LUN (Logical UNit) in block storage. In response to a request to take a snapshot of the file system or to provision a new file system, the NAS cluster bypasses the virtualization platform and directs a request to a block storage manager, either to take a snapshot of the LUN (in the case of snapshot) or to create a new LUN (in the case of provisioning). The NAS cluster records a relationships among LUNs, file systems, and snaps, but the virtualization platform treats the LUNs as independent objects.
