User mode network file system file lock method, device and equipment

Abstract

The invention discloses a user mode network file system file lock method, device and equipment, and the method comprises the steps: obtaining file lock request information sent by a client, and obtaining the corresponding file lock information according to the file lock request information; Obtaining a file lock operation request which is sent by the client and generated according to the file lockrequest information; Verifying the file lock operation request by using the file lock information; And if the verification is passed, calling a bottom distributed file system to respond to the file lock operation request. Therefore, according to the invention, the file lock technology and the distributed object storage NFS-Ganesha are combined; the data consistency of the distributed file systemin the concurrent access process is ensured through the file lock technology, so that the occurrence of a file conflict event is effectively avoided, and the stability of the system is improved.

Description

technical field [0001] The present application relates to the field of Linux network file systems, in particular to a file locking method, device and equipment of a user state network file system. Background technique [0002] NFS-Ganesha (Network File System User-space, the network file system user-space version) is an open source project as a user-space network file system. Among them, the user mode refers to only limited access to memory, and does not allow access to peripheral devices, the ability to occupy the CPU is deprived, and CPU resources can be obtained by other programs. NFS is a kernel-mode network file system. As one of the file systems supported by FreeBSD, it allows computers in the network to share resources through the TCP / IP network. Among them, the kernel mode means that the CPU can access all data in the memory, including peripheral devices, such as hard disks, network cards, etc., and the CPU can also switch itself from one program to another. In the ...

Problems solved by technology

[0004] However, as enterprise data becomes larger and larger, users have higher and higher requirements for data transmission performance and stability. In the current distributed object storage NFS-Ganesha, when multiple clients simultaneously access server files When this happens, it will cause data inconsistency, which will cause problems such as file conflicts and poor system stability.
