红帽全球峰会第 15 章 使用 NFS 创建导出
本节论述了如何使用 NFS 创建导出，然后可以从 OpenShift 集群外部访问。
按照以下步骤创建导出并从 OpenShift 集群外部访问它们：
15.1. 启用 NFS 功能

要使用 NFS 功能，您需要在集群创建后使用命令行界面(CLI)在存储集群中启用它。您还可以使用用户界面创建存储集群时启用 NFS 功能。
先决条件
- OpenShift Data Foundation 在 openshift-storage 命名空间中安装并运行。
- OpenShift Data Foundation 安装包含一个 CephFilesystem。
流程
- 运行以下命令通过 CLI 启用 NFS 功能：
oc --namespace openshift-storage patch storageclusters.ocs.openshift.io ocs-storagecluster --type merge --patch '{"spec": {"nfs":{"enable": true}}}'
$ oc --namespace openshift-storage patch storageclusters.ocs.openshift.io ocs-storagecluster --type merge --patch '{"spec": {"nfs":{"enable": true}}}'验证步骤
满足以下条件时，NFS 安装和配置已完成：
-
名为
ocs-storagecluster-cephnfs的 CephNFS 资源的状态为 Ready。 检查所有
csi-nfsplugin factorypod 是否正在运行：oc -n openshift-storage describe cephnfs ocs-storagecluster-cephnfs
oc -n openshift-storage describe cephnfs ocs-storagecluster-cephnfsCopy to Clipboard Copied! Toggle word wrap Toggle overflow oc -n openshift-storage get pod | grep csi-nfsplugin
