所有碎片都失败了 [英] All shards failed

问题描述

我正在进行弹性搜索，并且运行良好。今天，我刚刚重新启动了远程服务器（Ubuntu）。现在，我正在索引中搜索。

I was working on elastic search and it was working perfectly. Today I just restarted my remote server (Ubuntu). Now I am searching in my indexes, it is giving me this error.

{"error":"SearchPhaseExecutionException[Failed to execute phase [query_fetch], all shards failed]","status":503}

我还检查了健康。状态为红色。谁能告诉我问题是什么。

I also checked the health. The status is red. Can anyone tell me what's the issue.

推荐答案

重新启动时可能无法恢复某些分片，从而导致群集保持红色。

如果您点击：

http：//< yourhost>：9200 / _cluster / health /？level = shards ，则可以查找红色碎片。

It is possible on your restart some shards were not recovered, causing the cluster to stay red.
If you hit:
http://<yourhost>:9200/_cluster/health/?level=shards you can look for red shards.

我在重新启动时遇到了问题，即分片最终处于不可恢复的状态。我的解决方案是简单地完全删除该索引。对于每个人来说，这都不是理想的解决方案。

I have had issues on restart where shards end up in a non recoverable state. My solution was to simply delete that index completely. That is not an ideal solution for everyone.

使用类似这样的插件来可视化这样的问题也很不错：

Elasticsearch头

It is also nice to visualize issues like this with a plugin like:
Elasticsearch Head
