M/N upgrades - Error: Could not find class ::tripleo::trusted_cas

[Michele Baldessari]

After working around 1626422, during the major-upgrade-pacemaker-init.yaml step, I get the following on the compute node:
{
  "deploy_stdout": "",
  "deploy_stderr": "exception: connect failed\n\u001b[1;31mError: Could not find class ::tripleo::trusted_cas for overcloud-novacompute-0.localdomain on node overcloud-novacompute-0.localdomain\u001b[0m\n\u001b[1;31mError: Could not find
 class ::tripleo::trusted_cas for overcloud-novacompute-0.localdomain on node overcloud-novacompute-0.localdomain\u001b[0m\n",
  "deploy_status_code": 1
}

The reason this happens is that we added this in newton:
overcloud-resource-registry-puppet.yaml: OS::TripleO::Services::CACerts: puppet/services/ca-certs.yaml

But at this stage of the upgrade the nodes still have mitaka puppet modules and this one was
not yet present at mitaka release time.

Tentative workaround in environments/major-upgrade-pacemaker-init.yaml :
    OS::TripleO::Services::CACerts: OS::Heat::None

It is likely that we will need to noop more services. Will test this shortly

So I think until we actually upgrade puppet-tripleo to newton we need to disable all the new services that do not exist in mitaka/puppet-tripleo. The next one on the list is:
OS::TripleO::Services::Snmp: puppet/services/snmp.yaml

    No-op Puppet for upgrades/migrations according to composable roles

    Our previous no-ops stopped working because the Puppet run resources
    moved under a different entry in resource registry. This is now fixed
    to follow the latest way.
