Steps for controlling node placement from Director Installation Guide do not work

Solution Verified - Updated -


  • We are trying to deterministically place nodes so that Ironic Node A is always Controller 0 and so forth. This is documented in the Director Installation and Usage guide, section 6.3.1, but the steps provided in the guide result in an early deployment error.
  • Error seen:
Error: only 0 of 3 requested ironic nodes are tagged to profile control (for flavor control)
Recommendation: tag more nodes using ironic node-update <NODE ID> replace properties/capabilities=profile:control,boot_option:local
Error: only 0 of 1 requested ironic nodes are tagged to profile compute (for flavor compute)
Recommendation: tag more nodes using ironic node-update <NODE ID> replace properties/capabilities=profile:compute,boot_option:local
  • We tag the nodes per the guide like this:
 1011  ironic node-update <uuid> replace properties/capabilities='node:controller-0,boot_option:local'
 1013  ironic node-update <uuid> replace properties/capabilities='node:controller-1,boot_option:local'
 1015  ironic node-update <uuid> replace properties/capabilities='node:controller-2,boot_option:local'
 1018  ironic node-update <uuid> replace properties/capabilities='node:novacompute-0,boot_option:local'
  • And scheduler-hints.yaml looks like this:
[stack@undercloud templates]$ cat scheduler-hints.yaml
    'capabilities:node': 'controller-%index%'
    'capabilities:node': 'novacompute-%index%'
    overcloud-controller-0: <hostname>
    overcloud-controller-1: <hostname>
    overcloud-controller-2: <hostname>
    overcloud-compute-0: <hostname>
    overcloud-compute-1: <hostname>
  • Our deploy command looks like this:
openstack overcloud deploy --templates \
  -e ~/templates/scheduler-hints.yaml \
  -e /usr/share/openstack-tripleo-heat-templates/environments/network-isolation.yaml \
  -e /usr/share/openstack-tripleo-heat-templates/environments/network-management.yaml \
  -e ~/templates/ips-from-pool-all.yaml \
  -e ~/templates/network-environment.yaml \
  -e ~/templates/storage-environment.yaml \
  --control-scale 3 \
  --compute-scale 1 \
  --ceph-storage-scale 0 \
  --control-flavor control \
  --compute-flavor compute \
  --ceph-storage-flavor ceph-storage \
  --ntp-server \
  --neutron-network-type vxlan \
  --neutron-tunnel-types vxlan
