Abstract
A technique for operating a file system in a NAS (network attached storage) cluster includes discovering, by a data node running in the NAS cluster, a LUN (Logical UNit) provisioned from block storage. The data node renders the LUN as a block device and creates a local volume, built on the block device. The data node then deploys the file system on the local volume. The file system, the local volume, the block device, and the LUN all have address spaces, and the address space of each corresponds one-to-one with the address space of each of the others. Write requests directed to addresses in the file system propagate to the LUN, where they effect writes at corresponding addresses in the LUN.
