Problems solved by technology

[0004] However, in practical applications, when a server receives a message from another server, the server that sent the message may have unmounted the shared file system, or unmounted and remounted the shared file system, which will result in receiving The server of the message cannot process the message correctly or recognize the message as a serious error, resulting in problems such as server downtime or shared file system exceptions

Abstract

The application provides a message processing method and device for lock management of a shared file system and a server. When the server executes a mounting operation on the shared file system, a mounting cycle identifier corresponding to a mounting life cycle of the mounting operation is generated, the mounting cycle identifier is packaged into a mounting request, and the mounting request is sent to servers in a server cluster of the shared file system. After the server successfully mounts the shared file system, when a service interaction message is sent to the servers in the server cluster, a mounting cycle identifier corresponding to a current mounting life cycle is packaged in the service interaction message, and then the service interaction message is sent. Therefore, the basis forjudging whether the service interaction message is overdue can be provided for the servers receiving the service interaction message, so that when the service interaction message is overdue, processing is not carried out.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular, to a shared file system lock management message processing method, device and server. Background technique [0002] A shared file system is a file system that can be mounted on multiple servers in a server cluster at the same time. Each server that mounts the shared file system is called a node. operation, the results of the file operation can be seen on other nodes. [0003] At present, a shared file system usually adopts a distributed lock manager (Distributed Lock Manager, DLM) to ensure the consistency of data accessed by each node of the set. For a server in the server cluster, the period from when the server mounts the shared file system to when the shared file system is finally unmounted (umount) is called a mount life cycle of the server. During a mounting lifecycle, the server will receive messages sent by DLMs of other servers in the server cluster,...
