问题描述

今天发现当天的索引在ES中并没有创建,logstash中不停的报错:

[INFO ][logstash.outputs.elasticsearch] Retrying individual bulk actions that failed or were rejected by the previous bulk request. {:count=>1}
[INFO ][logstash.outputs.elasticsearch] retrying failed action with response code: 403 ({"type"=>"cluster_block_exception", "reason"=>"blocked by: [FORBIDDEN/12/index read-only / allow delete (api)];"})

索引变成了只读:

index read-only / allow delete (api)];"}

es报错,es报错也是索引只读错误

解决办法

经过分析,发现是因为ES所在服务器磁盘空间太低引起,具体解决办法如下:

在kibana开发控制台执行下面语句即可:

PUT _settings
{
  "index": {
    "blocks": {
      "read_only_allow_delete": "false"
    }
  }
}

执行语句

原因

一旦在存储超过95%的磁盘中的节点上分配了一个或多个分片的任何索引,该索引将被强制进入只读模式
