why do we need to unstack and stack it again when we turn off the system??
I'm a new to openstack and installed latest Havana in my laptop. After I shutdown it and restart it later, when I try to login into the dashboard even after entering the valid credentials it gives me error like Authentication failed.Then I unstack it and stack using ./stack.sh it works fine there after. What I want to know is why it is necessary and are there any specific reasons behind this.
Thanks in advance.
