AI Technical Summary

Technical Problem

Existing disaster recovery solutions only apply to object storage and fail to effectively address the disaster recovery issues of file systems, leading to business interruptions in the event of a disaster.

Method used

By using an object protocol for data interaction between the primary and secondary nodes, file system consistency is ensured. A conflict handling strategy is used to handle write request conflicts, improving interaction efficiency. Different file system protocols are supported to adapt to various application scenarios.

Benefits of technology

It enables efficient synchronization of the file systems of the primary and backup nodes in the event of a disaster, ensuring business continuity, reducing the difficulty of implementing data writing methods, and improving interaction efficiency and data consistency.

Abstract

A data writing method, system and device, in the application, the replication group includes a master node and a standby node, the master node and the standby node are deployed with a file system, the master node receives a first write request based on a first file system protocol, the first write request is used to request writing a first target data. In response to the first write request, the master node writes the first target data. The master node sends a second write request to the standby node according to the first write request through an object protocol, the second write request is used to request writing a first object, the first object includes the first target data; after receiving the second write request, the standby node processes the second write request in response to the second write request. The master node and the standby node interact through the object protocol, the master node can efficiently transmit the first target data to the standby node, and then the file systems on the master node and the standby node can be kept consistent, so that the replication group can cope with the disaster of the master node.
