Abstract
Embodiments of the invention relate to coordinated access to a clustered file system's shared storage subsystem using a shared-lock architecture. A particular file server is configured to coordinate the file system's file access layout particular server, in response to a client's file access layout request for byte-ranges of a file stored in the storage subsystem being received by a file server in cluster and sent to said particular server, generates a file access layout of a set of file servers for a parallel file access protocol to use and byte ranges of the file that particular individual file servers to use, to service an I/O request for the file. The file server (that received the request), sends the generated file access layout to said client, and requests coordinated access to said file from the particular server in response to receiving an I/O request to byte-ranges of said file.
