I am not sure but is this normal ? 

In rabbitmq.yml is this 

+++ b/ansible/rabbitmq.yml
@@ -0,0 +1,115 @@
+---
+# For RabbitMQ we need to be careful about restarting services, to avoid losing quorum.
+- name: Apply role rabbitmq
+  gather_facts: false
+  hosts:
+    - rabbitmq
+    - '&enable_rabbitmq_True'

But I can see during the upgrade restart every node at the same moment and then ther is some try to do it better ...

I mean is that restart before OK ? 

Thanks
