Openstack仪表板显示错误“错误:无法检索使用情况信息". [英] Openstack dashboard gives error "Error: Unable to retrieve usage information"

问题描述

我通过 devstack 在运行Ubuntu 14.04 LTS的ec2实例上安装了OpenStack.登录仪表板时，出现错误错误:无法检索使用情况信息" 当我安装并首次登录时，一切正常.但是在我停止ec2实例并重新启动后，我面临着这个问题. 是什么导致此错误? 我使用了稳定的juno版本的devstack. 我的ec2实例的AMI是Ubuntu Server 14.04 LTS(HVM)，SSD卷类型. 重新启动实例可能会引起一些问题吗?

I installed OpenStack on an ec2 instance running Ubuntu 14.04 LTS via devstack. When I login into the dashboard I get an error "Error: Unable to retrieve usage information" When I installed it and logged in for the first time, everything was working fine. But after I stopped my ec2 instance and restarted, I am facing this problem. What might be causing this error? I used the stable juno version of devstack. And the AMI for my ec2 instance is Ubuntu Server 14.04 LTS (HVM), SSD Volume Type. Does restarting the instance might have caused some problem?

推荐答案

cd到devstack并执行./rejoin-stack 那解决了.我试图分别重新启动nova和其他服务. 但是由于安装是使用devstack完成的，因此您需要运行./rejoin-stack脚本.

cd to devstack and execute ./rejoin-stack That solved it. I was trying to reboot nova and other services individually. But since the installation was done using devstack, you need to run the ./rejoin-stack script.
