Abstract
A technique for managing data storage provides multiple physical computing machines and block storage arranged in a NAS (network attached storage) cluster. The physical computing machines run NAS servers, with each NAS server including an FSDB (file system database) that identifies a set of file systems that belong to the NAS server. LUNs (Logical UNits) in the block storage provide backing store for the set of file systems of each NAS server. The NAS cluster performs a NAS server cloning operation in which an existing source NAS server is cloned in its entirety to create a separate clone NAS server, the operation automatically cloning all the separate file systems of the source NAS server and related metadata without a need for user involvement on a per-filesystem basis.
