摘要
Embodiments include a method comprising transmitting from a node of a plurality of nodes within a clustered file system provides concurrent file I/O access for files, to write access a region of a file. The method includes receiving an authorization to write access the region without a lock to preclude access of the region by other nodes, if at least one physical section in a machine-readable medium has been allocated for storage of the region by the server. The method includes receiving the authorization to write access the region with the lock to preclude access of the region by the other nodes, if the at least one physical section in the machine-readable medium has not been allocated for storage of the region by the server. Responsive to receiving the authorization to write access, metadata is transmitted for storage into the at least one physical section in the machine-readable medium.
