openstack nova - No rejoin-stack.sh script in my setup

Question

I've installed the "all-in-one" setup of DevStack.

But when I rebooted my system nothings works, and I lose all my already-created instances, images, configs, ...

I've found that I need to use the script rejoin-stack.sh but in my setup doesn't exists.

Please, any suggestions could help me, I'm blocked by the same problem since 1 week !

Answer 1

As mentioned elsewhere here, rejoin-stack.sh was recently removed. It was barely maintained and did not work for a lot of use cases, plus it encouraged an overall use case that DevStack is not intended to support, that of restoring a running stack after a reboot. You will need to run stack.sh and create a new cloud. Put the things that you always want done (like adding your public key, creating special flavors, etc) into local.sh and they will be done at the end of stack.sh.

DevStack is not meant and should not be used for running a cloud. If that is your need, please investigate one of the many alternatives that are designed and tested for cloud operation, including upgrades.
