Comment 3 for bug 1657716

This is expected behaviour due to fault tolerance settings

https://github.com/openstack/fuel-library/blob/stable/mitaka/deployment/puppet/deployment_groups/tasks.yaml

We run deployment for 300 nodes (even when we add 100 nodes only we need to adjust things on the other nodes), thus we have 6 compute nodes fault tolerance.

If you want to change this for a particular cluster, please do the following: copy paste deployment groups definition from
https://github.com/openstack/fuel-library/blob/stable/mitaka/deployment/puppet/deployment_groups/tasks.yaml

into a file called, e.g. default_cluster_<cluster_id>.yaml
then upload it into nailgun with

fuel2 graph upload -t default -e <cluster_id> -f default_cluster_<cluster_id>.yaml
