我有一个2个节点的ES集群.当我重新启动节点时,群集状态为黄色,因为某些分片未分配.我试图谷歌和常见的解决方案是重新路由未分配的分片.不幸的是,它对我不起作用.

所以它失败了,没有做任何改变.碎片仍处于未分配状态.
谢谢.

最佳答案 对于黄色的所有索引,您已配置2个副本：
health status index pri rep
yellow open logstash-log-2016.05.13 5 2
yellow open logstash-log-2016.05.12 5 2
yellow open .kibana 1 2
yellow open logstash-log-2016.05.11 5 2
yellow open logstash-log-2016.05.10 5 2
yellow open logstash-log-2016.05.17 5 2
yellow open logstash-log-2016.05.18 5 2
两个节点集群上的2个副本是不可能的.您需要第三个节点来分配所有副本.
或者,减少副本数量：
PUT /logstash-log-*,.kibana/_settings
{
"index": {
"number_of_replicas": 1
}
}
