Description
Technical Field
The present invention relates to the field of storage technologies, and in particular, to a method, an apparatus, a device, and a readable medium for creating a storage dual active volume by using a cluster.
Background
In the field of computers today, with the gradual penetration of hardware virtualization technology, container technology is getting popular among developers more and more with the advantage of 'one-time construction and deployment everywhere'. K8s (kubernetes, container scheduling engine) is used as a container cluster management system, and functions of automatic deployment, automatic expansion and contraction, maintenance and the like of the container clusters can be realized. CSI (Container Storage Interface) plug-in is a K8s defined container storage configuration interface that can provide persistent storage space for a cluster of containers.
K8s is an arrangement management tool of a portable container for container service, more and more companies are hugging K8s, and currently K8s has dominant cloud business processes, so that popularization and landing of hot technologies such as micro-service architecture and the like are promoted, and the development is still in favor.
Before the container technology, more virtual machines are developed, such as vmware and openstack, and a plurality of sub-computers (Linux) can be simulated in an operating system by using the virtual machines, wherein the sub-computers are isolated from each other, but the virtual machines have the defects of slow starting, large occupied space and difficult migration for development and operation staff. For example, an offline platform has been developed in vmware, so that in order to ensure that the virtual machine can be successfully used each time, the virtual machine is exported as an OVF and then carried around, and deployed in a server when the virtual machine is used, so that the defects of the virtual machine are fully reflected.
Then, the containerization technique has developed, which does not require the entire operating system to be virtualized, only requires a small-scale environment to be virtualized, and has a very fast start-up speed without consuming substantially additional system resources except for running applications therein. Dock is the most widely used container technology that creates a service by packaging images, launching the container. However, as applications become more complex, the number of containers becomes more and more, thereby deriving significant problems in managing the operation and maintenance containers, and as cloud computing develops, the cloud becomes the greatest challenge, and the containers drift. Under the driving of the service, k8s is introduced, a set of brand new distributed architecture leading scheme based on the container technology is provided, and the development of the whole container technology field is a great breakthrough and innovation.
The storage dual-activity characteristic means that two storage data centers which are mutually backed up are in an operation state, and when one data center fails, the service is automatically switched to the other data center. The problem that the conventional disaster recovery service can not be automatically switched is solved. A high level of data reliability and service continuity can be provided to the user.
The current CSI plug-in can only use a common storage pool to create a storage volume and mount the storage volume to a K8s container cluster for use. The dual-active storage pool is used for simultaneously storing two storage pools which are in a main-standby relation, the creation and the deletion of the dual-active storage volumes need to be simultaneously executed on the main pool and the standby pool, and the CSI plug-in does not provide the function of managing the dual-active storage pool.
