ES报错 ：原因最近ES里面有个索引一直保存，错误信息如下：

[021-0-03T09:54:15,328][INFO ][logstash.outputs.elasticsearch] retrying failed action with response code: 503 ({"type"=>"unavailable_shards_exception", "reason"=>"[gps_lte-mode-2021-.04.03][1] primary shard is not active Timeout: [1m], request: [BulkShardRequest [[gps_lte-mode-2021-.04.03][1]] containing [8] requests]"})
[2021--04-03T09:54:15,328][INFO ][logstash.outputs.elasticsearch] Retrying individual bulk actions that failed or were rejected by the previous bulk request. {:count=>25}

报错位置：在sync_tanle.cfg配置文件中 index索引一直保存没有去掉

解决方案一：修改index索引名称 例:j_product改为j_product1，然后杀死进程，重新同步

解决方案二、查看异常的index 命令：curl http://‘10.7.1.8:9200/_cat/indices’ | grep red

现有个索引异常了，直接进行删除即可。

[root@netmgmt-prod-elk-03 ~] curl http://'10.7.1.8:9200/_cat/indices' | grep red

删除命名：

 curl -XDELETE 'http://10.7.1.8:9200/gps_lte-mode-2021.04.03'
