Failed to restart rabbitmq-server during OpenStack environment update

which version of environment did you choose to update from and to ?

The initial version of Fuel was 5.0 and upgraded to 5.1.

this test case is invalid as we do not upgrade 5.0 envs to 5.1

I have confused the versions. So in fact I was updating 5.0 env to 5.0.2 (2014.1.1-5.0.2 to be exact).

The problem is that 5.0.2 contains a workaround for bug https://bugs.launchpad.net/mos/+bug/1341656 which requires rabbitmq service restart which may fail for some reason. As soon as this workaround is replaced by proper implementation we will not need to restart rabbitmq server and this bug will be fixed. Let's keep it open until https://bugs.launchpad.net/mos/+bug/1341656 is fixed and then close.

The review currently outstanding for bug #1341656 is about terminating rabbitmq connections:
https://review.openstack.org/117500

Is there also a rabbitmq restart code somewhere that also needs to be backed out to resolve this bug?

Restart of Rabbit should be out of scope for patching story. We should restart no more than just openstack services, as we update only openstack & its python deps packages. If, for some reason, we update something which requires rabbit restart - then we should revert those changes to puppet modules.

Fixed by merging https://review.openstack.org/#/c/117500/
