这个问题的原因和解决办法是什么？

Question

我在同一个ubuntu22.04VM中安装了Elasticsearch和Kibana 8.4.0，我尝试通过令牌连接它们，当我尝试创建令牌时，会得到以下错误：

kibana@kibana:/usr/share/elasticsearch/bin$ ./elasticsearch-create-enrollment-token -s kibana
./elasticsearch-env: line 78: /etc/default/elasticsearch: Permission denied
kibana@kibana:/usr/share/elasticsearch/bin$ sudo ./elasticsearch-create-enrollment-token -s kibana
17:02:36.334 [main] ERROR org.elasticsearch.xpack.security.enrollment.ExternalEnrollmentTokenGenerator - Error 429when calling GET https://192.168.43.157:9200/_security/api_key.

磁盘使用率超过洪泛级水印

这意味着磁盘已满，无法写入，因此Kibana无法写入.security-7索引以创建注册令牌。

您需要在我们的磁盘上腾出一些空间，然后情况就会自行解决。
