Abstract

The invention discloses a data transmission method and device based on a FUSE file system and an NFS protocol. The method comprises the following steps: calling a direct input/output (IO) function ofan operating system through a server of a network file system (NFS); receiving a to-be-transmitted file, wherein the to-be-transmitted file comprises an identifier of the direct IO function; and directly writing the to-be-transmitted file into a target file system based on a user space file system FUSE through a direct IO function. According to the method and the device, the technical problems that the concurrency of read-write data is influenced and the efficiency is relatively low due to the fact that a client needs to pass through a page cache at a server side when the client reads and writes the data to the server in related technologies are solved.

Description

technical field [0001] The invention relates to the field of data processing, in particular to a data transmission method and device based on a FUSE file system and an NFS protocol. Background technique [0002] In related technologies, when data is transmitted through FUSE and NFS, for data security, each write operation will trigger an additional fsync operation, and the POSIX protocol requires that the file-system must lock the file when implementing fsync; resulting in All write requests finally become serial in fsync, which seriously affects the concurrency of write, resulting in serious performance loss during multi-threaded write. [0003] For the above problems, no effective solution has been proposed yet. Contents of the invention [0004] The embodiment of the present invention provides a data transmission method and device based on the FUSE file system and the NFS protocol, so as to at least solve the problem that in the related art, when the client reads and w...
