Abstract

The embodiment of the invention discloses a CTDB virtual IP equalization allocation method, device and equipment, and a computer readable storage medium. The CTDB virtual IP equalization allocation method comprises the following steps: obtaining a loaded virtual IP and an idle virtual IP to be allocated in a current distributed storage cluster when adding a new storage node; and retaining the loaded virtual IP on a source storage node without drifting, and allocating each virtual IP to be allocated to each storage node of the distributed storage cluster evenly. The technical scheme provided bythe application can ensure that the loaded virtual IP do not drift, the client service is not interrupted, and the allocation of the virtual IP can be balanced; therefore, the case that the virtual IP is assigned to the same node and the corresponding load is assigned to the same node is avoided, the data processing performance of the distributed storage cluster is improved, and the stability andhigh availability of the distributed storage cluster are improved.

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 ...
