Problems solved by technology

Regardless of the mode, manual deployment is required. Once the high-availability environment is destroyed, it will be irreversible or cannot provide high-availability multiple times.
[0004] Aiming at the single high availability and irreversible problems of existing clusters in the market, clusters can only implement high availability that has been deployed or can only automatically build high availability once
After the failover of the high availability of the cluster, a new high availability system cannot be automatically reconstructed several times in a row to ensure the safety of the cluster. Once the cluster is damaged more than twice, the cluster system also faces a huge risk of malfunctioning or data loss

Embodiment Construction

[0013] The following clearly and completely describes the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0014] In the embodiment of the present invention, a method for realizing dynamic continuous high availability in a clustered storage system detects the status of cluster servers by periodically sending heartbeat packets. A new high-availability system is automatically reconstructed in the available server nodes, and at the same time, the data status between the high-availability servers is synchronized to maintain the state synchronization between the high-availability servers, so that the cluster can reach a stable high-availabilit...

Abstract

The invention discloses a method for achieving dynamic continuous high availability in a cluster storage system. The cluster server state is detected by periodically sending heartbeat packets; and when the servers fail to switch and destroy the high availability, the high availability reconstruction system is triggered to automatically reconstruct a new high availability system from the remainingavailable server nodes of the cluster, the data shape among the high availability servers is synchronized, and the state synchronization among the high availability servers is kept, so that the cluster reaches a stable high availability new state. According to the method, when the cluster has a fault and high-availability damage, a high-availability new state is automatically reconstructed, so that the high availability is always kept.

Description

technical field [0001] The invention relates to a storage system, in particular to a method for realizing dynamic continuous high availability in a cluster storage system. Background technique [0002] With the rapid growth of data, and the wide application of cloud technology and big data, servers need to process more and more data, and the servers required for data storage and computing grow linearly. Cluster technology ensures that high-performance services can be provided in a unified manner. However, with more and more server nodes in the cluster and the rapid growth of data to be processed, the probability of cluster and server failures is also increasing. How to ensure the continuous high performance of the cluster? Availability and continuous and stable provision of external services has become an urgent problem to be solved. Especially for the cluster system that provides important information data storage, whether it can provide continuous high availability become...
