Embodiment Construction

[0028] In order to solve the problem in the prior art that other cluster nodes cannot access files synchronously with the master node of the file, in order to enable multiple cluster nodes to perform synchronous and mutually exclusive access when accessing the cluster file system, the user data in the cluster file system is guaranteed As well as the integrity and consistency of metadata, the present invention provides a cluster file system access control method and cluster nodes for a computer cluster network system, that is, a file system access technology for a shared disk device, so that multiple cluster nodes can synchronize and interact with each other exclusive access to the cluster file system.

[0029] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present in...

Abstract

The invention discloses a control method for a cluster file system access and a cluster node. The method comprises the following steps: a cluster file system is established and mounted on a cluster node in the cluster system, the cluster point of a certain file in the cluster file system which is accessed for the first time is set as a main node of the file, and an integral locking token and a total byte locking token are distributed to the main node; under the condition that other cluster points access the file, the main node distributes the corresponding byte locking token to the other cluster points according to the request of other cluster points and sets the other cluster points as slave nodes; the main nodes or the slave nodes carry out read/write operation on the corresponding contents of the file according to the byte locking token, the main nodes update the corresponding contents of the file modified by the integral locking token according to the holding integral locking token and transmits the integral locking token to the slave nodes according to the request of the slave nodes so that the slave nodes update the corresponding contents of the file modified by the integral locking token.

Description

technical field [0001] The invention relates to the field of cluster technologies, in particular to a cluster file system access control method and cluster nodes. Background technique [0002] In related technologies, a computer cluster is a computer system that is connected through a group of loosely integrated computer software and hardware, and highly closely cooperates to complete computing work. A single computer in a cluster system is usually called a cluster node, and each cluster node is connected through a local area network. Cluster computers are often used to improve the computing speed and reliability of a single computer. [0003] With the rapid development of high-performance microprocessors, high-speed Internet and high-performance distributed computing, as well as the increasing demand for computing power in various applications, cluster technology has achieved rapid development. The cluster system has the characteristics of low cost, high performance, high...
