摘要
Embodiments of the invention relate to supporting coordinated access to a file system's shared disk storage subsystem using an automatic alignment of a parallel file access protocol and metadata management on a per object basis. A file server (among servers in the cluster) receives a client's request to access a file stored by the file system in the storage subsystem using a parallel file access protocol. If the file system has selected a file server to serve as a metadata manager of said file, the file server uses the selected file server to coordinate access to the file's metadata. If the file system has not selected a file server to serve as the metadata manager of the file, the file system selects the file server that received said request as the metadata manager for said file until a file close request operation is received.
