Open Stack

Hello,

I think the cause is you are running stack.sh everytime you restart
devstack which clears the configuration. rejoin-stack.sh can help for your
cause.

Before proceeding for running the script please associate the vg file with
a loop device with following command with root

losetup /dev/loop2 /opt/stack/data/stack-volumes-backing-file

Please use rejoin-stack.sh script located at your devstack installation
directory or /opt/stack/devstack
