新建集群时出现Unknown node，一般是cluster节点meet通信失败或者异步操作延迟导致，请在节点上执行cluster nodes看下这些Unknown 节点的nodeId是否已经存在。如果不存在请检查redis日志。通常是网络防火墙限制导致。

cluster nodes查看是有对应的nodeId的，但是还是包该错误

[elemman]

我也遇到这个问题

1. 防火墙已关闭
2. 用cluster nodes也有对应nodeId
3. 直接在机器上操作redis连接都是通的，请问这个有解决办法了没有？

[wuwo1952368901]

我也是这种情况，在meet时只有在自己的nodes.conf中有记录写进来，其他节点的都没有，请问这是正常的吗？

[githubname1024]

如遇到该问题，请确认如下信息，如检查后，仍有问题，可reopen或者重新提issue。

1. 在redis实例上，执行 cluster nodes 确认是否有该nodeId；
2. redis 实例间网络是否连通，是否被防火墙拦截；
3. 如网络确认正常，可重试部署任务，查看是否能够部署成功。

另，如果网络存在延迟或部署的第一次报上述错误，可以通过查看最终是否部署成功。默认上述异常对应的命令存在重试机制，如果因为网络延迟，可能会报异常，但如重试成功，不影响最终部署。
