或是这么删除 [grafana]组件？

扩一下内存试试

obd display-trace 38a3b574-696c-11f0-bf13-001551532502,是执行的这个命令看到的日志吗

#9

是的

#10

是扩主机的内存吗

#11

增加了虚拟机内存，可以启动了，但是重启后，数据库端口2883不通了，-停止集群后，再启动，又卡在同一个地方了，真梦幻。。。。

#12

请教下大师们，有什么办法解决吗

#13

向高手学习

#14

学习打卡 :smiling_face_with_three_hearts: :smiling_face_with_three_hearts: :+1:

#15

建议部署一台新集群，demo所含组件太多，如果机器性能较差就会遇到启动超时问题。
使用obd web部署一个试试

#16

铲除集群
obd cluster destroy demo
铲除后，重新运行obd demo，可以启动，启动后，obd cluster stop demo --停止集群，再obd cluster start demo --启动集群，还是卡在原来地方

Start grafana ok

删除重装
