Elasticsearch索引关闭，不会恢复，也不会打开

Question

我正在尝试恢复已关闭的索引，但任何尝试这样做都是不成功的。

GET /_cat/indices/显示：

green open  .fess_config.web_config            m7yOnyvERje6baMyvi5IHA  2 0     1   0    10kb    10kb
      close .suggest_analyzer                  fjKXYnKHSQOeVsqf_ETTVA                               
green open  .fess_user.group                   jyu086_5QUKmx9N64EHsRQ  5 0     0   0   1.2kb   1.2kb

GET /_cluster/health?level=indices&pretty根本不包含fjKXYnKHSQOeVsqf_ETTVA。

启动日志中还有没有提及<{strong> ¹ fjKXYnKHSQOeVsqf_ETTVA。

GET /.suggest_analyzer/fjKXYnKHSQOeVsqf_ETTVA/_recovery?human和
GET /.suggest_analyzer/fjKXYnKHSQOeVsqf_ETTVA/_open导致：

{
    "error": {
        "root_cause": [{
                "type": "index_closed_exception",
                "reason": "closed",
                "index_uuid": "fjKXYnKHSQOeVsqf_ETTVA",
                "index": ".suggest_analyzer"
            }
        ],
        "type": "index_closed_exception",
        "reason": "closed",
        "index_uuid": "fjKXYnKHSQOeVsqf_ETTVA",
        "index": ".suggest_analyzer"
    },
    "status": 400
}

GET /_recovery?human返回一切正常，但在回复中再次没有提到fjKXYnKHSQOeVsqf_ETTVA。

文件系统上也没有*recovery个文件：

那么如何强制ES打开这个索引呢？

¹ 由于文件丢失，索引的恢复失败了两次，但该问题已经解决，现在ES甚至不会尝试恢复/打开它。

Answer 1

解决：

POST /_all/_open

使用空的JSON正文{}

{
    "acknowledged": true,
    "shards_acknowledged": true
}

GET /_cat/indices/
