Abstract
A plurality of data mover computers control access to respective file systems in data storage. A network client serviced by any of the data movers can access each of the file systems. If a data mover receives a client request for access to a file in a file system to which access is controlled by another data mover, then the data mover that received the client request sends a metadata request to the data mover that controls access to the file system. The data mover that controls access to the file system responds by placing a lock on the file and returning metadata of the file. The data mover that received the client request uses the metadata to formulate a data access command that is used to access the file data in the file system over a bypass data path that bypasses the data mover computer that controls access to the file system.
