How can i restart the devstack services ? I am working with the master branch and there is no "rejoin stack.sh" file as other websites suggest ? Is there a clean way of doing it ?

Tip: Unless you are doing development for devstack I would suggest to switch to a stable branch. Learn from my mistake :P

rejoin-stack has never worked well, which was one of the reasons it was removed from devstack. See here for example: http://stackoverflow.com/questions/36.... So the answer is: Don't stop your devstack. If it's running in a VM, I suggest you save the VM state if you need to switch your machine off.

But the issue arises when I change the config file and want to restart the services again for the changes to take effect

change the config file, then just restart the affected services. E.g. to restart the nova scheduler, go to its screen screen -x stack -p n-sch, kill the foreground process and run it again.

Which version are you using? If its an older release, you can either download the rejoin-stack file from some previous openstack release/version

OR

you can stop it by running unstack.sh and then start it again with stack.sh

I am using the master branch. Dont know which devstack version it is. I wanted to avoid restarting with stack.sh as it takes a lot of time.
