红帽全球峰会7.14.16. 关于虚拟机的高可用性
您可以通过手动删除故障节点来触发虚拟机故障切换或配置补救节点，为虚拟机 (VM) 启用高可用性。
- 手动删除出现故障的节点
-
如果节点失败，且集群中没有部署机器健康检查，则带有
runStrategy: Always配置的虚拟机不会自动重新定位到健康的节点。要触发虚拟机故障切换，您必须手动删除Node对象。
- 配置补救节点
- 您可以通过从 OperatorHub 安装 Self Node Remediation Operator 或 Fence Agents Remediation Operator 来配置补救节点，并启用机器健康检查或节点补救检查。
如需有关补救、隔离和维护节点的更多信息，请参阅 Red Hat OpenShift 文档中的工作负载可用性。
