Embodiment Construction

[0016] With reference to the accompanying drawings, a detailed description will be given below of a high-availability cluster management method of the present invention that does not depend on shared storage.

[0017] The high-availability cluster management method of the present invention does not need to add additional storage devices, configure the cluster according to the requirements, and transmit the disk data synchronously or asynchronously through the block devices of the cluster nodes themselves and the network bandwidth limitation, so as to ensure the transmission of disk data between nodes and sharing; the high-availability cluster management method proposes a disk data transmission device that does not depend on shared storage, and the disk data transmission device includes a synchronization tracking module, a block data synchronization module, a data change mapping module and a synchronization link module.

[0018] The above-mentioned synchronization tracking modul...

Abstract

The invention discloses a high-availability cluster management method independent of shared storage. According to the method, no additional storage device needs to be added, a cluster is configured according to the requirements, disk data are synchronously or asynchronously transmitted by means of block devices of cluster nodes and network bandwidth limitation, and disk data transmission and share between nodes are ensured. According to the high-availability cluster management method, a disk data transmission device independent of shared storage is provided, the disk data transmission device comprises a synchronous tracking module, a block data synchronization module, a data change mapping module and a synchronization link module. According to the high-availability cluster management method, disk data transmission and share between the nodes are achieved through the block devices of the cluster nodes, cost caused by storage devices can be greatly reduced, and configuration complexity and cluster management risks are reduced.

Description

[0001] technical field [0002] The invention relates to a management method for disk data sharing in a high-availability cluster system, in particular to a high-availability cluster management method independent of shared storage. Background technique [0003] A high-availability cluster system refers to a system that can guarantee 24-hour uninterrupted business, can quickly restore business when a problem occurs in the system or application software, and can control the downtime to the minute level as much as possible. There are various types of business resources managed in the high-availability cluster system, including process resources, floating IP resources, service resources, script resources, disk resources, database monitoring resources, and middleware monitoring resources. Various resources and their monitoring resources can be customized according to application scenarios Customized configuration and management. Among them, the disk resources are used to store ...
