How to increase number of compute nodes doing TripleO QuickStart Deployment (RDO) ?

asked 2016-06-02 13:03:04 -0500

I try to reproduce setup per https://simplenfv.wordpress.com/2016/...
and update minimal template as follows

 # Define a single controller node and a single compute node.
overcloud_nodes:
  - name: control_0
    flavor: control

  - name: compute_0
    flavor: compute

  - name: compute_1
    flavor: compute

but I still get 1 Controller and 1 Compute node deployed in overcloud ( no errors reported )

Check extra_args section, I believe you skipped --compute-scale (X)
Working sample posted bellow :-

# Giving the undercloud additional CPUs can greatly improve heat's
# performance (and result in a shorter deploy time).
undercloud_vcpu: 4

control_memory: 8192
control_vcpu: 2
compute_memory: 8192
compute_vcpu: 2

# We set introspection to true and use only the minimal amount of nodes
# for this job, but test all defaults otherwise.
step_introspect: true

# Define a single controller node and a single compute node.
overcloud_nodes:
  - name: control_0
    flavor: control

  - name: compute_0
    flavor: compute

  - name: compute_1
    flavor: compute

# Tell tripleo how we want things done.
extra_args: >-
  --compute-scale 2 --neutron-network-type vxlan
  --neutron-tunnel-types vxlan
  --ntp-server pool.ntp.org

network_isolation: true

At least myself did exactly same mistake , but looking at ha.yml I noticed "--controller-scale 3" and got the idea.
