Description Jan Provaznik 2015-09-24 12:41:51 UTC

Description of problem:
When deleting overcloud nodes, nodes are deleted *before* RHELUnregistrationDeployment resource is being deleted. Then RHELUnregistrationDeployment is stuck in DELETE_IN_PROGRESS and overcloud stack is stuck in UPDATE_IN_PROGRESS.

Steven found out the root cause of the problem: RHELUnregistrationDeployment uses  ComputeNodesPostDeployment. And scale-down is treated as an
update, so ComputeNodesPostDeployment is updated *after* the Compute
ResourceGroup has been resized.

Version-Release number of selected component (if applicable):
openstack-tripleo-heat-templates-0.8.6-64.el7ost.noarch

Steps to Reproduce:
1. openstack overcloud deploy --templates --rhel-reg --reg-method portal --reg-org xxx --reg-activation-key 'key' --compute-scale 2
2. openstack overcloud node delete --templates --stack overcloud 86894343-a032-45f2-a619-122a23a3d5ba

Actual results:
Overcloud stack remains in UPDATE_IN_PROGRESS.

Expected results:
Stack update is completed.
