[Bug 1423427] [NEW] os-baremetal-node ext relies on presence of specific ironic node properties

  Thread Previous • Date Previous • • Thread Next 
Public bug reported:

A new test has been added to tempest to stress the os-baremetal-nodes
API extension.  The test periodically fails in the gate with traceback
in n-api log:

This hits only periodically and only when another tempest baremetal test
is running in parallel to the new test.  The other tests
(tempest.api.baremetal.*) create some nodes in Ironic with node
properties that are not the standard resource properties the
nova->ironic proxy expects (from
nova/api/openstack/compute/contrib/baremetal_nodes.py:201):

          for inode in ironic_nodes:
                node = {'id': inode.uuid,
                        'interfaces': [],
                        'host': 'IRONIC MANAGED',
                        'task_state': inode.provision_state,
                        'cpus': inode.properties['cpus'],
                        'memory_mb': inode.properties['memory_mb'],
                        'disk_gb': inode.properties['local_gb']}
                nodes.append(node)

The other tempest test is creating nodes with a different set of
properties:

 {u'cpu_arch': u'x86', u'cpu_num': 8, u'memory': 4096, u'storage': 1024}

Ironic node properties are meant to be an arbitrary json dict, so the
nova code needs to account for this in one way or another.
