第 5 章 创建镜像 StorageClass 资源

流程

1. 将以下 YAML 保存到文件 ocs-storagecluster-ceph-rbdmirror.yaml。

   allowVolumeExpansion: true
   apiVersion: storage.k8s.io/v1
   kind: StorageClass
   metadata:
     name: ocs-storagecluster-ceph-rbdmirror
   parameters:
     clusterID: openshift-storage
     csi.storage.k8s.io/controller-expand-secret-name: rook-csi-rbd-provisioner
     csi.storage.k8s.io/controller-expand-secret-namespace: openshift-storage
     csi.storage.k8s.io/fstype: ext4
     csi.storage.k8s.io/node-stage-secret-name: rook-csi-rbd-node
     csi.storage.k8s.io/node-stage-secret-namespace: openshift-storage
     csi.storage.k8s.io/provisioner-secret-name: rook-csi-rbd-provisioner
     csi.storage.k8s.io/provisioner-secret-namespace: openshift-storage
     imageFeatures: layering,exclusive-lock,object-map,fast-diff
     imageFormat: "2"
     pool: ocs-storagecluster-cephblockpool
   provisioner: openshift-storage.rbd.csi.ceph.com
   reclaimPolicy: Delete
   volumeBindingMode: Immediate

2. 在两个受管集群中创建文件。

   $ oc create -f ocs-storagecluster-ceph-rbdmirror.yaml

   输出示例：

   storageclass.storage.k8s.io/ocs-storagecluster-ceph-rbdmirror created
