openebs部署使用cstor-分布式（复制）

在Kubernetes环境中部署OpenEBS作为存储平台，并使用其cStor存储引擎创建分布式复制卷，可以通过以下步骤进行：

1. 安装OpenEBS Operator:

kubectl apply -f https://openebs.github.io/charts/openebs-operator.yaml

2. 创建存储池(Pool)，例如使用所有节点上的磁盘:

apiVersion: openebs.io/v1alpha1
kind: StoragePoolClaim
metadata:
  name: cstor-pool-create
spec:
  name: cstor-pool
  type: disk
  maxPools: 3
  poolSpec:
    poolType: striped
  disks:
    diskList:
    - diskList/node-1/disk1
    - diskList/node-2/disk1
    - diskList/node-3/disk1

3. 创建分布式复制卷(Volume)，假设存储池名称为cstor-pool:

apiVersion: openebs.io/v1alpha1
kind: CStorPoolCluster
metadata:
  name: cstor-pool-cluster
spec:
  pools:
    - poolSpec:
        poolType: striped
      replicaCount: 3
---
apiVersion: openebs.io/v1alpha1
kind: CStorVolume
metadata:
  name: cstor-vol-dist-rep
spec:
  capacity: 5Gi
  iqn: iqn.2016-09.com.openebs.cstor:cstor-vol-dist-rep
  targetip: 10.4.1.2
  targetport: "3260"
  casType: cstor
  replication: 3
  poolInfo:
    poolName: cstor-pool

4. 创建持久化卷(PersistentVolume, PV)和持久化卷请求(PersistentVolumeClaim, PVC):

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: cstor-pvc-dist-rep
spec:
  storageClassName: openebs-cstor
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: 5Gi

确保你的Kubernetes集群已经准备好，并且kubectl已经配置好可以访问该集群。以上步骤中的YAML文件需要根据你的实际环境进行相应的修改，例如磁盘的路径、CStorPoolCluster的配置、PV的存储类名称等。
