Elasticsearch read_only_allow_delete 自动设置

Question

我对 Elasticsearch 有疑问。我尝试了以下方法:

 $ curl -XPUT -H "Content-Type: application/json" \
     http://localhost:9200/_all/_settings \
       -d '{"index.blocks.read_only_allow_delete": false}'

我的设置:

"settings": {
  "index": {
    "number_of_shards": "5",
    "blocks": {
      "read_only_allow_delete": "true"
    },
    "provided_name": "new-index",
    "creation_date": "1515433832692",
    "analysis": {
      "filter": {
        "ngram_filter": {
          "type": "ngram",
          "min_gram": "2",
          "max_gram": "4"
        }
      },
      "analyzer": {
        "ngram_analyzer": {
          "filter": [
            "ngram_filter"
          ],
          "type": "custom",
          "tokenizer": "standard"
        }
      }
    },
    "number_of_replicas": "1",
    "uuid": "OSG7CNAWR9-G3QC75K4oQQ",
    "version": {
      "created": "6010199"
    }
  }
}

当我检查设置时，它看起来不错，但只有几秒钟 (3-5)，它仍然设置为 true。我不能添加新元素和查询任何东西，只有 _search 和 delete。

有人知道如何解决这个问题吗？

注意:我使用的是 Elasticsearch 版本:6.1.1

当硬盘空间不足时，Elasticsearch 会自动设置 "read_only_allow_delete": "true"。

找到占用您存储空间的文件并删除/移动它们。一旦您有足够的可用存储空间，通过 Kibana 中的开发工具运行以下命令:

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

或(通过终端):

$ curl -XPUT -H "Content-Type: application/json" \
   http://localhost:9200/_all/_settings \
     -d '{"index.blocks.read_only_allow_delete": false}'

如您的问题所述。
