红帽全球峰会2.2. 持久性卷（PV）
Service Telemetry Framework (STF)使用 Red Hat OpenShift Container Platform 中的持久性存储来请求持久性卷，以便 Prometheus 和 Elasticsearch 可以存储指标和事件。
当您通过 Service Telemetry Operator 启用持久性存储时，STF 部署请求的持久性卷声明(PVC)会导致访问模式为 RWO (ReadWriteOnce)。如果您的环境包含预置备的持久性卷，请确保 Red Hat OpenShift Container Platform 已配置的 storageClass 中提供了 RWO 卷。
