服务结构群集状态＆＃34;升级服务无法访问＆＃34;

Question

我有SF簇由3个标准A0节点组成。 我将集群扩展到1个节点并理解这是个坏主意，因为在这种状态下没有任何工作（即使是SF资源管理器也没有工作） 然后我将其缩放回3个节点并重新启动主缩放器。 现在，scaleset中的所有节点都已启动并正在运行，但SF群集状态为“＃34;升级服务无法访问＆＃34;”。 我看到了类似的问题Service Fabric Status: Upgrade service unreachable，建议将节点扩展到D2，但这并没有解决我的问题。 我通过RDP连接到一个节点，并且是一些事件日志：

Answer 1

如果通过将VM scale调整为1来缩小群集，则基本上会破坏群集，因为它需要至少3个节点。因此，唯一的方法是从头开始重新创建它。

如果你需要一个只包含1个节点的小型集群（比如用于测试目的），现在Azure中有一种方法可以创建单个节点集群，但是你无法扩展它，因为它不是特殊情况用于生产用途。

Answer 2

无法升级服务，如果群集的活动VM或节点的数量变为0，则会发生这种情况。就我而言，他是通过一次重新启动所有虚拟机而发生的。在这种状态下，节点可用并且正在运行，但是它们已与集群断开连接。

我已解决。
