Embodiment Construction

[0048] The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0049] The technical solution of the present application can be applied to a cluster such as a high-availability (HA) cluster, and the following uses the high-availability cluster as an example for illustration. Such asfigure 1 As shown, the high availability cluster may include at least two cluster nodes ( figure 1 3 cluster nodes are shown in ), the cluster nodes may be servers, computers and so on. In the present application, the high-availability cluster is pre-configured...

Abstract

The invention discloses a node isolation method and device, node equipment and a computer readable storage medium, and is applied to the technical field of operation and maintenance. The method comprises the following steps: monitoring whether a to-be-isolated cluster node exists in at least two cluster nodes or not; and if the to-be-isolated cluster node exists, deleting the key value corresponding to the to-be-isolated cluster node from a shared disk, so that the to-be-isolated cluster node performs a node isolation operation when detecting that the key value of the to-be-isolated cluster node is not stored in the shared disk, thereby releasing the cluster resources on the to-be-isolated cluster node. By the adoption of the method and device, cost reduction and operation and maintenancemanagement input reduction are facilitated.

Description

technical field [0001] The present application relates to the technical field of operation and maintenance, and in particular to a node isolation method, device, node device, and computer-readable storage medium. Background technique [0002] Node isolation (Fencing) is a key technology of a high availability (High Availability, abbreviation: HA) cluster, which is used to ensure the security and integrity of business data. The current node isolation solution under the open source HA cluster is to connect all nodes in the cluster to a power switch. If a node fails, it will directly cause the voltage of the node to be unstable or power off, so that the A power switch allows failed nodes to reboot or shut down for node isolation. That is to say, the current node isolation solution needs to purchase additional power switches, which increases the hardware cost and operation and maintenance management investment.
