1.2. 使用 RHACM 安装 OpenShift Data Foundation 逻辑卷管理器 Operator

流程

1. 使用您的 OpenShift 凭证登录 RHACM CLI。

   如需更多信息，请参阅安装 Red Hat Advanced Cluster Management for Kubernetes。

2. 创建要在其中创建策略的命名空间。

   # oc create ns lvm-policy-ns

3. 将以下 YAML 保存到带有名称（如 policy-lvm-operator.yaml ）的文件，以创建策略。

   # This policy verifies the installation of the official version of the {product-name-short}
   # Logical Volume Manager Operator on the managed clusters.
   # If set to "enforce" it installs the operator.
   # Used APIs: OLM, ODF-LVMO #https://github.com/operator-framework/operator-lifecycle-manager
   # https://github.com/red-hat-storage/lvm-operator

4. 运行以下命令在命名空间中创建策略：

   # oc create -f policy-lvm-operator.yaml -n lvm-policy-ns

   其中，policy-lvm-operator.yaml 是用于保存策略的文件的名称。

   这会在命名空间 lvm-policy-ns 中创建一个 Policy、PlacementRule 和 PlacementBinding。Policy 会在与放置规则（PlacementRule）匹配的集群中创建 Namespace, OperatorGroup, Subscription, 和 LVMCluster 资源。这会在与选择条件匹配的 SNO 集群上部署 Operator，并将其配置为设置所需资源以置备存储。在安装后，Operator 会使用所有未使用的磁盘。
