Problems solved by technology

[0004] However, the current dual-machine hot backup method has many disadvantages, such as the inability to accurately monitor whether the other server is working normally, resulting in misjudgment; the other is prone to split-brain situations, which makes the server database damaged, corrupted data

Embodiment Construction

[0015] combined with Figure 1-4 The technical solution of the present invention is described in detail.

[0016] See attached figure 1 , the entire dual-system hot standby system consists of two servers and one storage node, the two servers are respectively Node A and Node B, and the two servers are connected to the storage node through optical fibers. Divide a piece of disk space on the storage node as an arbitration area, and only allow specific processes to read and write to it, while the data generated by real-time services is stored in other partitions, that is, this partition is only used for arbitration, not for storage applications. The active node (one of Node A and Node B) and the backup node (the other of Node A and Node B) in the system regularly read and write to the arbitration area, and the backup node perceives the activity by judging a specific status bit The current working status of the node. When the arbitration area is controlled by the active node, th...

Abstract

The invention provides a dual-computer hot standby method based on a quorum diskmechanism. The dual-computer hot standby method based on the quorum disk mechanism is used for achieving backups of a plurality of servers. The servers compete with one another to obtain the right of control over an quorum area of a storage node, the server which successfully obtains the right of control over the quorum area becomes an active server, and the other servers are set to be backup servers. The active server updates a heartbeat value regularly, and the backup servers read the heartbeat value regularly. If the heartbeat value is not changed in a time period, it is determined that the active server is halted, the backup servers compete with one another again to obtain the right of control over the quorum area, and then a new active server is determined. The dual-computer hot standby method based on the quorum disk mechanism can accurately judge the working state of the active server, avoid misjudgment and the brain laceration situation, and ensure service continuity.

Description

technical field [0001] The invention relates to the technical field of server hot backup, in particular to a dual-machine hot backup method based on an arbitration disk mechanism. Background technique [0002] As a node of the network, the server stores and processes 80% of the data and information on the network. Therefore, it is also called the soul of the network. It is a high-performance computer that provides various services for client computers on the network. Users provide services such as centralized computing, information publishing and data management. Its high performance is mainly reflected in high-speed computing capabilities, long-term reliable operation, and powerful external data throughput capabilities. [0003] In order to provide reliable, continuous and uninterrupted services to the outside world, the server must have reliable stability to ensure the smooth progress of various real-time online services. Based on this, the online transaction interruptio...
