I am using Openstack from Mirantis I set up a cluster with a controller node, a compute node and a storage node. All worked good But when I added two controller nodes the deployment a very long time and progress very slowly ..It is normal ?

I would expect Fuel to use puppet technology for creating 3 Node HA Controller, rather then Triple0
Am I correct ?

Yes, Fuel advices Three controller nodes for High availability..But Mirantis is very weird

I would assume that this is normal . Dont forget that when you are adding new Controller you have add a layer of orchestration between the nodes (corosync etc) so a lot of data has to be replicated etc. I have also noticed that in my deployment. Adding a new controller takes twice as long ++ than adding a compute.

thank you, especially that Mirantis ask you to redeploy the compute and storage nodes
