扩展集群时 CephFS 性能不佳
具有许多小元数据操作的工作负载可能会因为在多站点 Data Foundation 集群上放置元数据服务器 pod (MDS)造成性能不佳。
SELinux 重新标记问题，带有大量文件
当将卷附加到 Red Hat OpenShift Container Platform 中的 pod 时，pod 有时无法启动或需要很长时间才能启动。这个行为是通用的，它绑定到 Kubelet 如何处理 SELinux 重新标记。对于任何基于文件系统的卷，会发现这个问题。在 OpenShift Data Foundation 中，使用基于 CephFS 的卷和大量文件时会出现此问题。解决此问题的方法有多种。根据您的业务需求，您可以从知识库解决方案 https://access.redhat.com/solutions/6221251 中选择一个临时解决方案。
