Method and system for calling of CSI LVM Plugin and dynamic persistent volume supply and medium

Abstract

The invention provides a method and system for calling of a CSI LVM Plugin and dynamic persistent volume supply and a medium. The method comprises the steps: dividing SAN storage equipment into a plurality of LUN storage equipment; mapping one LUN storage device to a plurality of physical machine nodes; creating a volume group at the physical machine node; deploying a kubernetes cluster at a plurality of physical machine nodes, wherein the kubernetes cluster comprises a plurality of Pods; registering a CSI LVM Plugin is registered in the kubernetes cluster; enabling the kubernetes PVC to apply to create a persistent volume, and enabling the node server component to call the Create Volume to create a logical volume on the basis of a volume group; configuring a CSI LVM provider module in the controller server component, mapping the logical volume to the persistent volume through the CSI LVM provider module, and mounting the logical volume to the Pod, so that the local persistent volume is dynamically supplied to the Pod, the logical volume comes from the same volume group, and meanwhile, the sharing of the volume group is also realized.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method, system and medium for invoking a CSI LVM Plugin plug-in and dynamic persistent volume supply. Background technique [0002] A Storage Area Network (SAN for short) connects storage arrays and server hosts to establish an area network dedicated to data storage. SAN itself is a storage network that undertakes the task of data storage. The SAN network is isolated from the LAN service network, and the storage data flow will not occupy the service network bandwidth. SAN makes more full use of storage space and more effective installation and management. In addition, the SAN storage architecture realizes direct block-level storage access to physical hardware, which improves storage performance and upgradeability.

Problems solved by technology

[0003] Kubernetes is an open-source container scheduling platform across host clusters. It can automate the deployment, expansion and operation of application containers and provide a container-centric infrastructure. The Kubernetes platform provides a variety of storage volume management modes, including persistent storage , temporary storage, dynamic storage, static storage, different storage types provide different capabilities; SAN is a widely used enterprise-level stable product, kubernetes can provide support, but due to the variety of SAN storage products, native kubernetes can only do basic access function, which requires SAN storage vendors to provide their own CSI storage plug-ins. Usually, a new generation of SAN storage devices will provide dedicated CSI storage plug-ins, and the SAN storage that enterprises have purchased and are still using in the past often supports limited In addition, the container platform in Kubernetes is a combination of one or more containers. In the existing technology, if local persistent volumes are to be provided for the container platform for storage, it usually needs to be manually configured, which is time-consuming, laborious, and efficient. Low; in view of the above defects, how to adopt a unified method to integrate with the kubernetes platform for SAN storage products in different historical periods, and at the same time dynamically provide local persistent volumes for the container platform of the kubernetes platform has become a technical problem that needs to be solved urgently
