我有两个相同的服务器，我在一个服务器上设置了弹性搜索，并在其中导入了大约200万条记录。我现在希望其他服务器具有相同的记录集，并且这两个服务器作为一对工作，只需要一个服务器关闭我可以快速从群集中删除它，它将正常工作，没有插入新数据读。我按照我在网上找到的信息，并设置我的主机找到对方。看起来索引没有转移到我在复制的分片状态中看到的其他服务器，但它们的数据目录中的大小永远不会增加。
我用它作为指针。
How to add a new node to my Elasticsearch cluster
我的问题是，我可以scp将300gb以上的数据复制到数据目录中，还是弹性搜索需要这样做？

为了在两个（或更多）Elasticsearch节点之间复制数据，您需要添加replicas。对于索引（pelias）和主机（192.168.1.1:9200），可以使用以下curl命令添加一个副本：
curl -XPUT 'http://192.168.1.1:9200/pelias/_settings' -d '{
"index": {
"number_of_replicas": 1
}
}'
顺便说一句，感谢您使用Pelias，我是核心维护者之一：）
我还维护了一组bash脚本来完成常见的Elasticsearch任务here。有一个专门针对adding replicas的脚本，您或其他人可能会觉得有用。
