一、前置要求
- isisc
- 系统盘之外的额外磁盘,不需要先格式化
二、安装
kubectl apply -f https://openebs.github.io/charts/cstor-operator.yaml
等待 operator 服务正常启动
kubectl get bd -n openebs
operator 服务正常启动之后,通过 kubectl get bd -n openebs
会自动读取 node 上的可用磁盘,读取需要的 node 上的信息,保存为下面的文件内容
apiVersion: cstor.openebs.io/v1
kind: CStorPoolCluster
metadata:
name: cstor-disk-pool
namespace: openebs
spec:
pools:
- nodeSelector:
kubernetes.io/hostname: "node1"
dataRaidGroups:
- blockDevices:
- blockDeviceName: "blockdevice-3213a3bb3822161df3732b0321de495a"
poolConfig:
dataRaidGroupType: "stripe"
执行上面的 yaml 之后,我们的存储资源池就创建好了,再创建 sc 就可以正常使用了
kind: StorageClass
apiVersion: storage.k8s.io/v1
metadata:
name: cstor-csi-disk
provisioner: cstor.csi.openebs.io
allowVolumeExpansion: true
parameters:
cas-type: cstor
# cstorPoolCluster should have the name of the CSPC
cstorPoolCluster: cstor-disk-pool
# replicaCount should be <= no. of CSPI created in the selected CSPC
replicaCount: "1"
需要注意的是,replicaCount 的值,要小于等于上面 pool 的数量
