Hello, I deployed two devstack's on Ubuntu and CentOS, they worked well after stacked, but after OS reboot, both of them fail to restart the stack, i use the following command to restart the stacks. "screen -c stack-screenrc" What is the problem ? And how to exit the screen console ? ========================================= 董 建 华 地址：杭州滨江区南环路3766号新世纪办公楼 邮编：310053 手机：13857132818 总机：0571-28996000 传真：0571-28996001 热线：4006728686 网址：www.ahope.com.cn Email：dongjh at ahope.com.cn -------------- next part -------------- An HTML attachment was scrubbed...
