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 live volume by a cluster.
Background
In the field of computers today, with the gradual deepening of hardware virtualization technology, the container technology is more and more popular with developers due to the advantages of 'one-time construction and everywhere deployment'. The K8s (kubernets, container scheduling engine) as a container cluster management system can implement the functions of automatic deployment, automatic expansion and contraction, maintenance and the like of a container cluster. The CSI (container Storage interface) plug-in is a container Storage configuration interface defined by K8s and can provide a persistent Storage space for the container cluster.
K8s is an orchestration management tool for portable containers for container services, more and more companies are embracing K8s, and K8s has dominated cloud business processes, promoting popularization and falling of hot technologies such as micro-service architecture, and is developing vigorously.
Before the container technology, many 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 start, large occupied space and difficulty in migration for development and operation and maintenance personnel. For example, an offline platform is developed in vmware, and in order to ensure that the virtual machine can be used smoothly each time, the virtual machine is exported as an OVF, then the OVF is carried around, and the OVF is deployed in a server when being used, so that the defects of the virtual machine are fully embodied.
Then, the container technology comes up, it does not need to virtualize the whole operating system, only needs to virtualize a small-scale environment, and the starting speed is very fast, except running the application therein, basically does not consume extra system resources. Docker is the most widely used container technology, and creates a service by packaging images and starting containers. However, as applications become more complex, the number of containers also becomes more and more, which leads to a significant problem of managing operation and maintenance containers, and as cloud computing develops, the cloud end has the greatest challenge, and the containers drift. Under the drive of the service, k8s comes out, a set of brand-new container technology-based distributed architecture leading scheme is provided, and the development in the whole container technology field is a major breakthrough and innovation.
The storage dual-active characteristic means that two storage data centers which are backups of each other are in an operating state, and when one data center fails, a service is automatically switched to the other data center. The problem that the traditional disaster recovery service cannot 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 create storage volumes using ordinary storage pools and mount to the K8s container cluster for use. The dual-active storage pool has two storage pools which are in a primary-standby relationship at the same time, the creation and deletion of the dual-active storage pool are required to be executed on the primary pool and the standby pool at the same time, and the CSI plug-in does not provide the function of managing the dual-active storage pool.

In this embodiment, when creating a volume using a Storage pool through a CSI (Container Storage Interface) plug-in, a Storage pool class (Storage type) needs to be created first to specify a Storage pool type, a Storage pool name, a Storage pool IO group name, and the like to be used. To use the dual active pool, the following definitions are added to the StorageClass configuration file: adding a double-active pool type, such as aa, to the storage pool type volLevel, and identifying the used storage pool type as a double-active storage pool; identifying a pool name of one double-active storage pool by using volPoolName, and identifying a pool name of the other double-active storage pool by using volAuxPoolName; the storage pool IO group name is used for identifying one storage pool IO group name by using volIOGrp and identifying the other storage pool IO group name by using volAuxPoolName.

The CSI is an industry standard interface specification jointly formulated by community members from kubernets, messes, Docker, and the like, and is intended to expose any storage system to containerized applications. To assist storage providers in developing CSI-compatible plug-ins, kubernets officials have provided some CSI sidecar containers.
The CSI specification defines a minimum operating set and deployment recommendation for a storage provider to implement a CSI compatible Volume plug. The main focus of the CSI specification is to declare the interface that Volume plug must implement.

Before the container technology, many 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 start, large occupied space and difficulty in migration for development and operation and maintenance personnel. For example, an offline platform is developed in vmware, and in order to ensure that the virtual machine can be used smoothly each time, the virtual machine is exported as an OVF, then the OVF is carried around, and the OVF is deployed in a server when being used, so that the defects of the virtual machine are fully embodied.
