昨天在我们群主的帮助下，成功安装完成了All-in-one单节点，今天将单节点删除后，再安装Multi-node，还是报之前遇到过的两类问题：

  1. 节点找不到，错误信息如下：
    2020-05-15 18:59:33,204 p=23124 u=root | fatal: [k8sphere02]: FAILED! => {

    }
    STDERR:

    MSG:

2020-05-15 18:59:33,349 p=23124 u=root | fatal: [k8sphere03]: FAILED! => {

}
STDERR:

  1. ks-installer安装报错
    fatal: [k8sphere01]: FAILED! => {
    “attempts”: 30,
    “changed”: true,
    “cmd”: “/usr/local/bin/kubectl get pod -n kubesphere-system | grep Running | grep ks-installer”,
    “delta”: “0:00:00.072270”,
    “end”: “2020-05-15 19:15:20.891646″,

    “start”: “2020-05-15 19:15:20.819376”
    }
    MSG:

执行以下命令，结果如下：

这不是说明原因了吗， 0/1 nodes are available: 1 node(s) had taints that the pod didn’t tolerate.

还有这个 Error from server (NotFound): nodes “k8sphere02″ not found

    rayzhou2017 我也明白都是因为两个node找不到，可我检查了很多篇，也没有发现是啥原因导致其找不到啊！看看大家遇到这种问题，是怎么解决的？

      rayzhou2017 在我的部署中出现过好几次这种问题：

      1. 第一次是两个node（k8sphere02,k8sphere03），其中一个k8sphere02找不到；
      2. 第二次是我换一个新node（k8sphere03,glusterfs-client）,能正常；
      3. 后来都卸载后，再次安装1master+2node（k8sphere02,k8sphere03），发现两个node都找不到了。

          Feynman master节点可以ssh其它节点， ssh的要求是每个节点需要相互ssh吗？
