[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 invention provides a data migration method and device in a cluster, computer equipment and a storage medium, the method is applied to an OpenStack controller of the cluster, the data migration method in the cluster comprises the following steps: obtaining a detection domain in the cluster, and carrying out partition processing on the detection domain to obtain a plurality of detection subdomains; determining a main node in each detection subdomain, and configuring the Corosync software in the main node; on the basis of the cluster node in each detection subdomain, carrying out heartbeat detection by adopting Corosync software to obtain a detection result, and sending the detection result to an OpenStack controller; and migrating the data in the cluster according to a detection result.Cluster center hop detection is effectively prevented from being limited by the scale of nodes in the cluster, heartbeat detection time delay and network bandwidth occupied by heartbeat detection timedelay are reduced, and resource scheduling efficiency in the cluster is effectively improved.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a data migration method, device, computer equipment and storage medium 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. Each node in the cluster communicates with each other through the internal LAN. When a node fails, the tasks running on the node will be migrated to another node to prevent single point 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, in which the computing node cluster is responsible for providing computing virtualization functions, that is, tenant virtual machines. [0003] In related technologies, a Heartbeat Agent running on eac...
