Hi All, I have used ./rejoin-stack.sh as suggested by floren & alfredo. But debugging has stucked at the * cinder.volume.manager: unable to instantiate the volume. * I found then one blog: http://fosshelp.blogspot.in/2013/11/openstack-devstack-httpconnectionpool.html During unstack & stack, machine gets hanged. So I shutdown it. After that, I have rebooted and start stack.sh again. And this time I am getting * keystone service die* *stack.sh:311* keystone did not start Where should I look for troubleshooting the problem? Seeking for guidance, Thanks !! *--* *Cheers,* *Mayur* -------------- next part -------------- An HTML attachment was scrubbed...
