RHEL unregistration doesn't work when scaling down
Last modified: 2015-10-08 08:19:42 EDT
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.
