Description Sid Ahmed Sadouni 2017-07-11 06:13:17 EDT
We are using the env file environments/neutron-ml2-cisco-nexus-ucsm.yaml for cisco_ucsm mechanism driver and composable role for our needs in NFV.

environments/neutron-ml2-cisco-nexus-ucsm.yaml  calls puppet/extraconfig/all_nodes/neutron-ml2-cisco-nexus-ucsm.yaml which is not "composable role ready"

We are in a case for NFV where we need different type of compute role.

For the 'Compute like' role we configure, the parameter ucsm_host_list is not generated.
This is a problem when we want to spawn a VM with an SR-IOV interface on a compute.

I would like TripleO experts to chime in on this issue. Obviously, the final solution would be for config for Cisco mech drivers to be compossible role compatible. Since, this issue has to be fixed in OSP10, a different solution needs to be found in the meantime.

I am currently looking at:

I think the reason, compute hosts with different compute roles are being ignored is because of this:
    type: OS::Heat::SoftwareDeployments
      name: CollectMacDeploymentsCompute
      servers:  {get_param: [servers, Compute]}  <-----
      config: {get_resource: CollectMacConfig}
      actions: ['CREATE'] # Only do this on CREATE

Looking for suggestions from the Triple experts. Can the "Compute" string be a regular expression? Or, should be create a block like this for every compute role (brute force, I know)?

Opened a new triple bug: https://bugs.launchpad.net/tripleo/+bug/1704853
describing the issue as I see it.
Comment 4 Sandhya Dasu 2017-07-27 09:55:44 EDT
Fix has been back ported to stable/newton via:https://review.openstack.org/#/c/487164/.
This needs to make its way into OSP10.
