Or use the new devstack v2 ;)

I use Devstack for development purposes and the environment settings are critical for me. So, once my Devstack setup is done,
I usually take a snapshot and hence whenever anything gets screwed up, I simply fire the snapshot. Also I keep my source code files
on a mounted drive (nfs share exported from my laptop) so that -->  a.  the snapshot doesn't affect it
                                                                                        b.  I can use eclipse + pydev with the source code being on my laptop.

 However, I found it be a good exercise to restart the services manually after the VM reboots.

Hope it helps,
Deepak

Someone has already done this.  The last message in the thread mentioned it, but perhaps you missed it:

Hi Vish,

Thanks. I just have a weird thought. Based on the stack.sh logs I understand that when I run stack.sh second time it simply spawns all the services.
Ex: I saw the below in stack.sh log

' screen -S stack -p n-net -X stuff 'cd /opt/stack/nova && /opt/stack/nova/bin/nova-network
+ screen_it n-sch 'cd /opt/stack/nova && /opt/stack/nova/bin/nova-scheduler'

Can I write my own upstart script that will start all the services when the system is booting instead of running stack.sh manually, might be a script which init can execute while booting? Will that be ok for connecting to the dashboard again?

Thanks,
NandaKumar Raghavan

That is correct.  Devstack is primarily for development.  It isn't really designed to be a production ready system.

Hi,

I have similar query. I had installed open stack using devstack on a freshly installed stand-alone machine(not vm). For the first time once the stack.sh is completed I was able to connect to the dashboard and all the services are up and running. Once I rebooted the box, all my settings are gone and I am not able to connect the dashboard as none of the services were running. I had to run stack.sh again and I was able to connect to the dashboard. Whether installing open stack using devstack is not persistent across reboots? Running stack.sh again is the only solution or is there any other way I can do ?

Thanks in advance.

Regards,
NandaKumar Raghavan
