【问题描述】:
由于磁盘空间不足,我想从节点中删除所有索引。请注意,我只有一个节点,并且我在本地机器上运行弹性服务器。
基本上,当我启动弹性服务器时,它会失败并显示以下日志 -
[2020-12-13T22:06:51,839][WARN ][o.e.c.r.a.DiskThresholdMonitor] [sedna] flood stage disk watermark [95%] exceeded on [k7t835EJQ6KzPu-7a-aW8Q][sedna][/home/ssahoo/elasticsearch-7.10.0/data/nodes/0] free: 879mb[0.8%], all indices on this node will be marked read-only
在终端上我收到以下错误 -
Could not rename log file 'logs/gc.log' to 'logs/gc.log.05' (Reserved).

因此,我想通过删除所有索引以及节点来释放空间。那么如何删除我拥有的单个节点?
或者如果我可以问一下您的建议是什么来克服这个问题?我负担不起额外的磁盘空间,这是我的主要限制。
谢谢。
【问题讨论】:
-
如果你想删除节点,你为什么不直接卸载它呢?弹性数据位于数据文件夹中。所以很容易删除所有内容。 elastic.co/guide/en/elasticsearch/reference/2.0/…
-
但是我需要使用弹性搜索以供以后使用,因此我需要重新安装它。
-
没有其他安全的方法来删除节点,因为我不再需要旧索引
