Windows 10下Elasticsearch索引删除失效及数据存储位置求助

Hey there, let's work through this problem step by step—since you're using the portable (unzipped) versions of these tools, the cleanup process is straightforward once you cover all the bases.

先明确数据存储的核心位置 #

First, let's confirm where your data lives:

• Elasticsearch: By default, all index data is stored in the data folder inside your Elasticsearch unzipped directory. You mentioned seeing indexes here, which checks out. If you ever modified the elasticsearch.yml file's path.data setting, that's the actual path you need to target instead.
• Kibana: It also has its own data folder (usually in kibana-[version]/data) where it stores internal indexes (like .kibana) and cached data—this is probably why you still saw "existing indexes" in Kibana after deleting ES indexes.
• Logstash: The portable version might keep temporary queue data in its own data folder (logstash-[version]/data), which can take up space if there were unprocessed events.

彻底清理的分步操作（Windows 10） #

Follow these steps to ensure you free up all that disk space and remove leftover indexes:

1. 完全停止所有相关进程
   Don't just close the command windows—open Task Manager (Ctrl+Shift+Esc), go to the Details tab, and end any running processes named:

   • elasticsearch.exe
   • logstash.exe
   • kibana.exe
     This ensures no files are locked, so you can delete them without issues.

2. 删除Elasticsearch的data目录
   Navigate to your Elasticsearch unzipped folder, delete the entire data folder (not just individual index subfolders). This wipes all ES indexes completely.

3. 清理Kibana的data目录
   Go to your Kibana unzipped folder, delete its data folder too. This resets Kibana's internal state, so it won't show "ghost" indexes anymore once you restart.

4. 清理Logstash的临时数据
   Head to your Logstash unzipped folder, delete its data folder. This removes any pending queue data that might be taking up space.

5. 验证清理效果
   Restart Elasticsearch, then Kibana (wait a minute for them to fully boot up). Open Kibana's Dev Tools, run this command to confirm no indexes exist:

   GET _cat/indices?v
   

   You should see an empty list (except maybe Kibana's new internal indexes if you haven't disabled them). Check your disk space now—it should reflect the freed up space.

额外注意事项 #

• If you had any custom path.data settings in elasticsearch.yml, make sure you delete the folder specified there instead of the default data folder.
• Always back up any important data before deleting these folders—once they're gone, there's no way to recover the indexes.
