Fault notification method, device and apparatus and computer readable storage medium

Abstract

The invention discloses a fault notification method based on a user mode network file system. The method is based on a target end, and comprises the following steps: monitoring fault notification information sent by an opposite end after restarting, and sending the fault notification information of the opposite end to the opposite end after restarting the opposite end; wherein the target end is aclient or a server; if the target end is the server end, releasing a file lock held by the target client after fault notification information sent by the target client of the opposite end is monitored; and if the target end is the client, after fault notification information sent by the target server of the opposite end is monitored, applying the authorized file lock to the target server again within the grace period. Reliability of the file lock can be improved, and the consistency of data in a network file system is guaranteed. The invention further discloses a fault notification device andapparatus based on the user mode network file system and a computer readable storage medium, and the above technical effects can also be achieved.

Description

Technical field [0001] The present invention relates to, more specifically, to a method, device, equipment and computer-readable storage medium for fault notification based on a user-mode network file system. Background technique [0002] At present, as enterprise data becomes larger and larger, users have higher and higher requirements for data transmission performance and stability. Storage servers will have a huge number of clients. Multiple clients will access files on the server at the same time. As a result of file conflicts, various clients collaborate with each other to ensure file data consistency has become the focus of software users and developers. Therefore, it is particularly important to provide an efficient, reliable, easy to implement and maintain, and highly consistent network file system file lock. In the network file system file lock application, in failure scenarios, such as client restart, abnormal downtime, server restart, abnormal downtime, abnormal netwo...

AI Technical Summary

Problems solved by technology

In the network file system file lock application, in failure scenarios, such as client restart, abnormal downtime, server restart, abnormal downtime, abnormal network interruption, etc., the server and client often do not know that the other party has a failure. At this time, there will be problems of file lock release and untimely application, which will reduce the reliability of file locks.
