karbon错误在棱镜元素中看不到任何错误

我有一个Dev Nutanix群集，我用来托管Kubernetes簇。今天，我在其中添加了一个大的kuberentes群集（我打算将其添加到我的prod nutanix群集中，但意外地添加到了Dev Nutanix群集中）。

我开始从Dev Nutanix集群上托管的3个Kubernetes群集中的2个中获得很多警报。安装完成后，我从Dev Nutanix群集中删除了大型Kubernetes群集。

我认为，由于资源都已释放，因此集群会很好。但是我在使用`kubectl'时仍会遇到错误。

最常见的两个是：

服务器中的错误：ETCDSERVER：请求超时

和

无法连接到服务器：拨号TCP 10.62.12.91：443：Connectex：由于目标机积极拒绝，因此无法建立连接。

10.62.12.91是我的控制平面主机。

我试图重新启动ETCD服务器和控制平面主机。这没有解决这个问题。

我将Dev Nutanix群集加载到PRIM元素中，并且没有给出任何错误（只有几个警告是无支撑的快照功能等）。

它表明有很多内存，CPU和磁盘空间可用。

Karbon显示了几个错误警报，但现在只有一个头说：警报：普罗米修斯未能获取警报

我该如何修复我的kubernetescluster？

Hi @Vaccano<\/user-mention><\/p>

I see you have restarted your instances with no luck. Not sure if you followed the following order:<\/p>

  • Shutdown the VMs<\/li>\t
  • Start etcd first (wait at least 2 minutes)<\/li>\t
  • Start control plane (wait at least 1 minute)<\/li>\t
  • Start the workers<\/li><\/ul>

    If this doesn\u2019t solve the problem, I suggest you open a support case.<\/p>","className":"post__content__best_answer"}">

I have a Dev Nutanix Cluster that I use to host Kubernetes clusters.\u00a0 Today I added a large Kuberentes cluster to it (I intended to add it to my Prod Nutanix Cluster, but accidentally added to my Dev Nutanix Cluster).<\/p>

I started to get a lot of alerts from 2 of the 3 Kubernetes clusters hosted on the Dev Nutanix Cluster.\u00a0 As soon as the install was complete, I deleted the large Kubernetes cluster from the Dev Nutanix Cluster.<\/p>

I figured that since the resources have all been freed up, the cluster would be fine.\u00a0 But I am still getting errors when using `kubectl`.<\/p>

The two most common are:<\/p>

Error from server: etcdserver: request timed out<\/code><\/p>

and<\/p>

Unable to connect to the server: dial tcp 10.62.12.91:443: connectex: No connection could be made because the target machine actively refused it.<\/code><\/p>

10.62.12.91 is my control plane host.<\/p>

I have tried to reboot both the etcd server and my control plane host.\u00a0 That did not fix the issue.<\/p>

I loaded up the Dev Nutanix Cluster in Prim Element and it does not give any errors (only a few warnings that are around unsupported snapshot features and such).\u00a0<\/p>

It shows that there is plenty of Memory, CPU and Disk Space available.<\/p>

Karbon was showing several error alerts, but now just has a header saying: Alerts: Prometheus failed to fetch alerts<\/strong><\/p>

How can I go about fixing my Kubernetescluster?<\/p>

你好 @vaccano

我看到您没有运气重新启动您的实例。不确定您是否遵循以下订单：

  • 关闭VM
  • 首先开始ETCD（至少等待2分钟）
  • 启动控制平面（至少等待1分钟）
  • 开始工人

如果这无法解决问题，建议您打开支持案例。
