Bug 1308419

Description of problem:

I'm not able to add a new compute node to a deployed overcloud environment following the steps described on the official documentation https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux_OpenStack_Platform/7/html-single/Director_Installation_and_Usage/index.html#sect-Advanced-Registering_Nodes_for_the_Advanced_Overcloud.

The update operation ends with this error:

2016-02-12 12:15:46 overcloud UPDATE_IN_PROGRESS Stack UPDATE started

Version-Release number of selected component (if applicable):

Red Hat Enterprise Linux Server release 7.2 (Maipo)
openstack-tripleo-heat-templates-0.8.7-2.el7ost.noarch
instack-undercloud-2.2.1-2.el7ost.noarch

How reproducible:

Deploy an overcloud with a command line similar to this one:

openstack overcloud deploy --templates --libvirt-type=kvm --ntp-server 10.5.26.10 --control-scale 3 --compute-scale 1 --ceph-storage-scale 0 --block-storage-scale 0 --swift-storage-scale 0 --control-flavor baremetal --compute-flavor baremetal --ceph-storage-flavor baremetal --block-storage-flavor baremetal --swift-storage-flavor baremetal -e /usr/share/openstack-tripleo-heat-templates/environments/puppet-pacemaker.yaml -e /usr/share/openstack-tripleo-heat-templates/environments/network-isolation.yaml -e /usr/share/openstack-tripleo-heat-templates/environments/net-single-nic-with-vlans.yaml -e /home/stack/network-environment.yaml --neutron-bridge-mappings datacentre:br-floating

And after the successful deployment, try to add the new compute node:

$ openstack baremetal import --json newnodes.json
$ ironic node-list
$ ironic node-set-maintenance [NODE UUID] true
$ openstack baremetal introspection start [NODE UUID]
$ ironic node-set-maintenance [NODE UUID] false
$ ironic node-update [NODE UUID] add properties/capabilities='profile:baremetal,boot_option:local'
$ ironic node-update [NODE UUID] add driver_info/deploy_kernel='09b40e3d-0382-4925-a356-3a4b4f36b514'
$ ironic node-update [NODE UUID] add driver_info/deploy_ramdisk='765a46af-4417-4592-91e5-a300ead3faf6'
$ openstack overcloud deploy --templates --compute-scale 3 -e [...]

Actual results:

Failure (see error above).

Expected results:

New compute nodes should become available.
