Abstract

The embodiment of the invention discloses a CTDB virtual IP balanced distribution method, device, equipment and computer-readable storage medium. Among them, the method includes when adding a new storage node, obtaining the virtual IP with load and idle virtual IP to be allocated in the current distributed storage cluster; keeping the virtual IP with load on the source storage node without drifting, and Each virtual IP to be allocated is evenly allocated to each storage node of the distributed storage cluster. The technical solution provided by this application can not only ensure that the virtual IP with load does not drift, and the client service is not interrupted, but also can balance the distribution of virtual IP, avoiding the situation that the virtual IP is allocated to the same node and the corresponding load is allocated to the same node. Improve the data processing performance of distributed storage clusters, and improve the stability and high availability of distributed storage clusters.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of distributed storage, and in particular to a CTDB virtual IP balanced allocation method, device, equipment and computer-readable storage medium. Background technique [0002] Distributed storage is a cluster composed of multiple storage node servers. It supports a copy of data to be stored on multiple storage nodes. Each storage node can obtain complete data through inter-node communication. When a storage node goes down, Complete data recovery can be performed according to the configured strategy. [0003] CTDB is a high-availability management file system that relies on clustering. It can be shared among all nodes participating in the CTDB cluster, and is used to monitor the status of cluster nodes and the allocation of virtual IPs. When a cluster node fails, the virtual IP assigned to the node will drift to other nodes, and the read and write services of the failed node will also ...
