Open Stack

@Bob Ball
My goal is that I want to reboot devstack DomU without reinstall devstack.

Thanks to @ALL

I finally reboot devstack successfully without reinstalling.in my case by
this way.


First
I add  `exit 0` before the first line of stack.sh to stop openstack
running.

Then i  use these commands to start the services.


cd /etc/apache2/sites-enabled && sudo ln -s ../sites-available/keystone.conf
sudo  service apache2 restart
sudo service rabbitmq-server restart
sudo service mysql restart
sudo service tgt restart
truncate -s 10737418240 /opt/stack/data/stack-volumes-default-backing-file
truncate -s
10737418240 /opt/stack/data/stack-volumes-lvmdriver-1-backing-file
sudo losetup -f --show /opt/stack/data/stack-volumes-default-backing-file
CINDER_DEVICE=`sudo losetup -f
--show /opt/stack/data/stack-volumes-lvmdriver-1-backing-file`
sudo pvcreate $CINDER_DEVICE
sudo vgcreate  stack-volumes-lvmdriver-1 $CINDER_DEVICE
cd /opt/stack/devstack/   && ./rejoin-stack.sh


Some data are lost such as the data in lvm volume used by cinder. But  most
of my data are kept.
