<p class="MsoNormal"><span style="color:#1F497D">The disable_worker_services file was originally created to prevent the (bare metal) nova-compute services from running on a newly upgraded controller in an AIO-DX configuration, until we swacted to that controller.
This was necessary because nova does not support communication between a newer version of nova-compute and older versions of nova-conductor. This situation no longer exists because the bare metal nova-compute services do not exist after our transition to containers.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">Unfortunately, the disable_worker_services file was also used when we first switched to containers, as a quick and dirty way of disabling the bare metal OpenStack services (this is done in the stx-puppet/puppet-manifests/src/modules/platform/manifests/kubernetes.pp).
By always creating this file it caused the missing alarm issue in the bug you are working on.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">I think the proper solution here is to remove all references to the disable_worker_services file from the codebase - this flag is no longer needed. This would also include removing the worker_services init script,
which is also unnecessary.<o:p></o:p></span></p>
