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 manages access to a file system namespace for a set of file systems, including for example Distributed File System (DFS) typically accessed using the Server Message Block (SMB) protocol, by clients of different types, including for example clients using the Network File System (NFS) protocol.
