因为我的磁盘空间快用完了，所以我想从节点中删除所有索引。请注意，我只有一个节点，并且正在本地计算机上运行弹性服务器。
基本上，当我启动elastic服务器时，它会失败，出现以下日志-

[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，我得到以下错误-

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和节点来释放空间。那么，如何删除我拥有的单个节点呢？
或者如果我可以问一下你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。
谢谢您。
