Problems solved by technology

[0004] In this way, since the heartbeat detection between nodes and the election of the master node need to be performed through network interaction messages, as the cluster scale expands, the interaction delay of heartbeat detection increases, and the network bandwidth resources are too large, and corosync nodes The specifications are limited to 128 units, and the actual measurement is even smaller

Abstract

The present invention proposes a data migration method and device in a cluster. The method is applied to the OpenStack controller of the cluster. The data migration method in the cluster includes acquiring detection domains in the cluster, and partitioning the detection domains to obtain multiple detection domains. Sub-domain; determine the master node in each detection sub-domain, and configure the Corosync software in the master node; based on the cluster nodes in each detection sub-domain, use Corosync software to perform heartbeat detection, obtain the detection results, and send the detection results to OpenStack controller; migrate data in the cluster according to the detection results. The present invention can effectively prevent the heartbeat detection of the cluster from being limited by the scale of nodes in the cluster, reduce the heartbeat detection time delay and the network bandwidth it occupies, and effectively improve the resource scheduling efficiency in the cluster.

Description

Technical field [0001] The present invention relates to the field of Internet technology, in particular to a data migration method and device in a cluster. Background technique [0002] A cluster refers to a group of servers (called nodes) that work together to provide resources or services to the outside world as a whole. The nodes in the cluster communicate with each other through the internal LAN. When a node fails, the tasks running on that node will be migrated to another node to prevent single points of failure. This attribute can be called HA (High Availability, high Availability). OpenStack is an open source cloud computing management platform project that provides an infrastructure as a service (Infrastructure AS A Service, IAAS) solution. Among them, the computing node cluster is responsible for providing computing virtualization functions, that is, tenants' virtual machines. [0003] In related technologies, the Heartbeat Agent running on each computing node, such as t...
