Bug 2103907

I'm assuming the yaml you're passing to the overcloud node provision command looks like this:

- name: Controller
  count: 3
- name: Compute
  count: 2

The nodes will be assigned based on allocation criteria which doesn't take into account node names that exactly match hostnames.

To confirm this could you paste the output for all of these:
baremetal node list
baremetal allocation list
metalsmith list

I agree this situation is confusing so I proposed this fix a few weeks ago:

https://review.opendev.org/c/openstack/ironic/+/845856

This would need to be backported to wallaby, which may not be acceptable to upstream, so worst case the fix will be targeted at 18.0.

You can have predictable placement by mapping names to hostnames in the yaml as per the documentation[1]:

- name: Controller
  count: 3
  instances:
  - hostname: controller-0
    name: controller-0
  - hostname: controller-1
    name: controller-1
  - hostname: controller-2
    name: controller-2
- name: Compute
  count: 2
  instances:
  - hostname: compute-0
    name: compute-0
  - hostname: compute-1
    name: compute-1

I think people are hitting this a lot in testing because this is how infrared names nodes, but I do wonder how often customers will choose a node naming scheme which exactly matches the overcloud hostname. I'm sure it will happen sometimes but generally nodes will have names including hardware type, position in rack, etc.

Hello Steve:

This is the baremetal deployment yaml file: https://paste.opendev.org/show/bZ7QYMguqwphkZ6mRD4t/. That's right, we don't assign the name of the resources, just the number.

The "metalsmith list" command was reported in the description: https://paste.opendev.org/show/bqbKX2PoxnF0xUwlcpwh/

I don't have the "baremetal" binary installed in the system.

Regards.

Lets track the fix in bug #2110729
