Description of problem: When re-deploying RHELOSP, if the same Director is used and if the Overcloud has been deployed, there is an error on the Installation Progress page: Error Expected(201) <=> Actual(409 Conflict) response => #<Excon::Response:0x0000000ed3d0c0 @data={:body=>"{\"explanation\": \"There was a conflict when trying to complete your request.\", \"code\": 409, \"error\": {\"message\": \"The Stack (overcloud) already exists.\", \"traceback\": \"Traceback (most recent call last):\\n\\n File \\\"/usr/lib/python2.7/site-packages/heat/common/context.py\\\", line 300, in wrapped\\n return func(self, ctx, *args, **kwargs)\\n\\n File \\\"/usr/lib/python2.7/site-packages/heat/engine/service.py\\\", line 670, in create_stack\\n parent_resource_name)\\n\\n File \\\"/usr/lib/python2.7/site-packages/heat/engine/service.py\\\", line 566, in _parse_template_and_validate_stack\\n self._validate_new_stack(cnxt, stack_name, tmpl)\\n\\n File \\\"/usr/lib/python2.7/site-packages/heat/engine/service.py\\\", line 531, in _validate_new_stack\\n raise exception.StackExists(stack_name=stack_name)\\n\\nStackExists: The Stack (overcloud) already exists.\\n\", \"type\": \"StackExists\"}, \"title\": \"Conflict\"}", :headers=>{"Content-Type"=>"application/json; charset=UTF-8", "Content-Length"=>"898", "X-Openstack-Request-Id"=>"req-03dc90e9-c60b-4ddb-a0c4-156ab9c0acc0", "Date"=>"Mon, 07 Dec 2015 08:18:53 GMT"}, :status=>409, :remote_ip=>"192.0.2.1", :local_port=><SNIP>, :local_address=>"<SNIP>"}, @body="{\"explanation\": \"There was a conflict when trying to complete your request.\", \"code\": 409, \"error\": {\"message\": \"The Stack (overcloud) already exists.\", \"traceback\": \"Traceback (most recent call last):\\n\\n File \\\"/usr/lib/python2.7/site-packages/heat/common/context.py\\\", line 300, in wrapped\\n return func(self, ctx, *args, **kwargs)\\n\\n File \\\"/usr/lib/python2.7/site-packages/heat/engine/service.py\\\", line 670, in create_stack\\n parent_resource_name)\\n\\n File \\\"/usr/lib/python2.7/site-packages/heat/engine/service.py\\\", line 566, in _parse_template_and_validate_stack\\n self._validate_new_stack(cnxt, stack_name, tmpl)\\n\\n File \\\"/usr/lib/python2.7/site-packages/heat/engine/service.py\\\", line 531, in _validate_new_stack\\n raise exception.StackExists(stack_name=stack_name)\\n\\nStackExists: The Stack (overcloud) already exists.\\n\", \"type\": \"StackExists\"}, \"title\": \"Conflict\"}", @headers={"Content-Type"=>"application/json; charset=UTF-8", "Content-Length"=>"898", "X-Openstack-Request-Id"=>"req-03dc90e9-c60b-4ddb-a0c4-156ab9c0acc0", "Date"=>"Mon, 07 Dec 2015 08:18:53 GMT"}, @status=409, @remote_ip="192.0.2.1", @local_port=<SNIP>, @local_address="<SNIP>"> I suspect this might be a fairly common situation, so there should appear a message about Overcloud, but no traceback in webUI. Traceback is also in production.log, so no data will be lost. Version-Release number of selected component (if applicable): RHCI-6.0-RHEL-7-20151201.t.0 RHCIOOO-7-RHEL-7-20151201.t.1 How reproducible: Always Steps to Reproduce: 1. Do a deployment of RHELOSP with deployed Overcloud 2. Start new deployment of RHELOSP, use the same Director 3. Content sync successful, during installation the above error appears Actual results: Error with traceback appears on the Installation Progress screen Expected results: Error without traceback should appear on the Installation Progress screen Additional info:
Maybe as part of our predeployment validation we check to ensure the overcloud is not already deployed, so it doesn't happen after sync'ing content?
Also see this with RHCIOOO-7-RHEL-7-20160122.t.0
Potential Workaround: Director: heat stack-delete overcloud wait for heat stack-list finish DELETE_IN_PROGRESS Resume step
Verified on QCI-1.2-RHEL-7-20160720.t.0 w/ QCIOOO-8.0-RHEL-7-20160719.t.0.
