Elasticsearch集群UNASSIGNED shareds问题 修复
线上有3台es组成集群，其他有两台非正常关机了，早上过来发现集群状态为红色，提示"24 UNASSIGNED shareds": 1）查看集群相关信息： curl'localhost:9200/_nodes/process?pretty' 记下这个node的id号； 2）然后找出UNASSIGNED 的相关信息，方便后续修改！ # curl -XGET http://localhost:9200/_cat/shards|grep UNASSIGNED % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed 100 30528 100 30528 0 0 705k 0 --:--:-- --:--:-- --:--:-- 745k graylog_83 1 p UNASSIGNED graylog_83 1 r UNASSIGNED graylog_83 0 p UNASSIGNED graylog_83 0 r UNASSIGNED graylog_82 1 p UNASSIGNED graylog_82 1 r UNASSIGNED graylog_85 2 p UNASSIGNED graylog_85 2 r UNASSIGNED graylog_85 1 p UNASSIGNED graylog_85 1 r UNASSIGNED graylog_84 0 p UNASSIGNED graylog_84 0 r UNASSIGNED graylog_87 1 p UNASSIGNED graylog_87 1 r UNASSIGNED graylog_86 3 p UNASSIGNED graylog_86 3 r UNASSIGNED graylog_86 1 p UNASSIGNED graylog_86 1 r UNASSIGNED graylog_89 3 p UNASSIGNED graylog_89 3 r UNASSIGNED graylog_88 1 p UNASSIGNED graylog_88 1 r UNASSIGNED graylog_88 0 p UNASSIGNED graylog_88 0 r UNASSIGNED 3）然后依次修改以上UNASSIGNED ，命令为： curl -XPOST 'localhost:9200/_cluster/reroute' -d '{ "commands" : [ { "allocate" : { "index" : "graylog_83", "shard" : 1, "node" : "Auq82gfGQVWgOBw6S7ajRQ", "allow_primary" : true } }] }' PS： index就是索引的名称：也就是graylog_88,graylog_86,graylog_87..... node:就是在哪个节点上执行； shared：分片的编号！ 本文转自 shine_forever 51CTO博客，原文链接:http://blog.51cto.com/shineforever/1859734
