kibana报错

报错1：Unable to navigate to space \"default\", redirecting to Space Selector. Error: Saved object [space/default] not found

kibana是通过从 artifacthub 中下载的chart安装的，运行一段时间后开发反馈说kibana挂了，于是登录机器执行命令 kubectl get pod 看到 READY 为 0/1 ，查看日志报错如下

{"type":"log","@timestamp":"2022-06-13T08:40:09Z","tags":["spaces","error"],"pid":1,"message":"Unable to navigate to space \"default\", redirecting to Space Selector. Error: Saved object [space/default] not found"}
{"type":"response","@timestamp":"2022-06-13T08:40:09Z","tags":[],"pid":1,"method":"get","statusCode":302,"req":{"url":"/app/kibana","method":"get","headers":{"user-agent":"curl/7.29.0","host":"localhost:5601","accept":"*/*"},"remoteAddress":"127.0.0.1","userAgent":"127.0.0.1"},"res":{"statusCode":302,"responseTime":1,"contentLength":9},"message":"GET /app/kibana 302 1ms - 9.0B"}

暂时的结局方式是删除pod后重启，然后就可以了，但是运行一段时间后kibana又会自动挂掉

谷歌 Unable to navigate to space \"default\", redirecting to Space Selector. Error: Saved object [space/default] not found 找到一些链接有人也遇到过同样的问题

在github这个isseu中可以看到 https://github.com/elastic/kibana/issues/35213

在es的官方论坛中有人提到过解决方法 https://discuss.elastic.co/t/unable-to-navigate-to-space-default-redirecting-to-space-selector-error-saved-object-space-default-not-found/177393/3

官方给到的解释是当存储空间很低时，kibana会把 .kibana 索引设置为只读，从而导致日志中的只读报错，可以通过如下命令解决此问题

在这个链接中可以看到解决方法

PUT _settings
  {
  "index": {
  "blocks": {
  "read_only_allow_delete": "false"
  }
  }
  }

PUT your_index_name/_settings
  {
  "index": {
  "blocks": {
  "read_only_allow_delete": "false"
  }
  }
  }
