Service Fabric群集状态为“无法升级服务". [英] Service Fabric Cluster status "Upgrade service unreachable"

问题描述

我有3个标准A0节点组成的SF集群.我将群集扩展到1个节点，并了解到这是一个坏主意，因为在此状态下没有任何工作(即使SF Explorer也无法工作)然后，将其扩展到3个节点，然后重新启动Primary scaleser.现在，scaleset中的所有节点都已启动并正在运行，但是SF群集状态为无法升级服务".我看到了类似的问题服务结构状态:升级服务无法访问建议在哪里进行扩展节点达到D2，但这并不能解决我的问题.我已经通过RDP连接到一个节点，并且有一些事件日志:

I Had SF cluster made of 3 Standard A0 nodes. I scaled cluster in to 1 node and understood that this was bad idea because nothing was working in this state (even SF explorer was not working) Then I scaled it out back to 3 nodes and restarted Primary scaleser. Now all nodes in scaleset are up and running but SF cluster status is "Upgrade service unreachable". I saw similar question Service Fabric Status: Upgrade service unreachable where was recommended to scale nodes up to D2 but this hasn't solve my problem. I have connected to one node via RDP and are some Event logs:

推荐答案

如果通过将VM缩放比例设置为1来缩小集群规模，则基本上是在破坏集群，因为根据设计，它至少需要3个节点.因此，唯一的方法是从头开始重新创建它.

If you are scaling down the cluster by resizing VM scale set to 1 you're basically destroying the cluster because it requires a minimum of 3 nodes by design. Therefore the only way is to recreate it again from scratch.

如果您需要一个仅包含1个节点的小型群集(例如出于测试目的)，Azure中现在可以创建一个单节点群集，但是您无法对其进行扩展，因为这是一种特殊情况供生产使用.

If you need a tiny cluster consisting of just 1 node (like for testing purposes) there is a way in Azure now to create a single node cluster, but you won't be able to scale it as it's a special case not for production use.
