接入未知存储

简介

Pelicon 可以利用 StorageProvider CRD 接入暂时未受支持的存储设备,不过这种方式接入的存储只能具备一些基础的能力。

接入的前提条件:

1. 目标存储符合CSI规范
2. 目标存储运行正常

使用

1. 按需修改以下yaml,并apply

apiVersion: uds.dce.daocloud.io/v1
kind: StorageProvider
metadata:
  annotations:
    uds.dce.daocloud.io/capabilities: '{"snapshot":true,"clone":true,"expansion":true,"protocol":"block"}'     # Storage capabilities
  name: ceph-rbd-1.0.0
spec:
  driver: rbd.csi.ceph.com    # Provision name
  vendor: ceph                # Storage vendor name
  product: rbd                # Storage product
  protocol: block             # Storage protocal(block/file/local)
  version: 1.0.0              # Version

2. 查看

kubectl get sp

xsky-block-4.1.x       xsky       SDS        block      4.1.x     iscsi.csi.xsky.com          Ready          Ready           Ready           312d
xsky-file-4.1.x        xsky       SDS        file       4.1.x     nfs.csi.xsky.com            Ready          Ready           NotInstalled    244d

3. (可选) 管理CSI组件

如果你想让Pelicon识别存储系统的CSI组件,以此监控CSI的运行状态,并展示在StorageProvider CR的Status中,需要为CSI Controller和CSI Driver打标签(假设CSI组件全部是deployment).

kubectl label deployment <your-csi-controller> driver=<you provisioner name> role=csi-controller
kubectl label deployment <your-csi-driver> driver=<you provisioner name> role=csi-driver
