Elasticsearch沒有正確分配碎片和副本

我正在運行一個2節點的elasticsearch集羣，並將所有索引配置爲2個主碎片和1個副本。起初我以爲每個節點都會存儲1個主碎片和1個副本，儘管這不是偶然發生的事情。Elasticsearch沒有正確分配碎片和副本

curl -XGET http://localhost:9200/_cat/shards

如上所示，每個分片由單個節點託管，並且沒有分配副本。

curl -XGET 'http://127.0.0.1:9200/_cluster/health?pretty=true' 
{ 
    "cluster_name" : "es_gts_seginfo", 
    "status" : "yellow", 
    "timed_out" : false, 
    "number_of_nodes" : 2, 
    "number_of_data_nodes" : 2, 
    "active_primary_shards" : 9, 
    "active_shards" : 9, 
    "relocating_shards" : 0, 
    "initializing_shards" : 0, 
    "unassigned_shards" : 9, 
    "delayed_unassigned_shards" : 0, 
    "number_of_pending_tasks" : 0, 
    "number_of_in_flight_fetch" : 0, 
    "task_max_waiting_in_queue_millis" : 0, 
    "active_shards_percent_as_number" : 50.0 
}

我在做什麼錯？

你能發佈你的集羣設置嗎？你是否在彈性搜索日誌中看到任何東西？ 'curl -XPOST「的輸出是什麼？http：// localhost：9200/_cluster/reroute？explain' –

您是否嘗試過這裏提到的步驟：http://stackoverflow.com/a/23816954/689625。對每個節點的分片數量進行限制？https://www.elastic.co/guide/en/elasticsearch/reference/current/allocation-total-shards.html – jay

您可以顯示節點的網絡配置嗎？他們「看到」對方，即他們是否發現了對方？ – Val

感謝大家，我能弄清楚這個問題。我的一個節點運行2.4.0，另一個運行2.4.1。這種重新路由不能正常工作。

>  "index" : ".kibana",

>  "allow_primary":true 
>  } 
> } ] }' http://localhost:9200/_cluster/reroute?pretty

    "root_cause" : [ {

    } ],

    },
