Description Dmitry Tantsur 2016-12-06 16:49:20 UTC

Currently introspection fails when a node has no disks. We need a new API/CLI flag to mark a node as diskless, to allow introspection on it to pass. We probably also need a global option to treat all nodes as diskless.

Then we need Ironic inspection interface to provide this flag based on presence of a valid storage_interface field (to be introduced as part of BFV).

Update on the upstream status: code merged, present in Ocata (inspector version 5.0)
Changing status to ON_QA;

Comment 10 mlammon 2017-07-20 20:21:17 UTC

This was tested in a kvm virtual environment successfully. 

Steps:
install osp 12 undercloud with several nodes (i.e 3 controller, 2 compute, 1 <spare>)
On hypervisor, virsh detach-disk --domain <spare> --target vda --persistent
openstack baremetal import --json ~/instackenv.json  # contains 
openstack baremetal configure boot
openstack baremetal introspection bulk start
openstack baremetal list  # look for the uuid of <spare> used for 0 disk
openstack baremetal node show <uuid> | grep properties

As expected result:
The introspection succeeded now with one bare metal and property "u'local_gb': u'0'"

Comment 12 mlammon 2017-07-20 20:38:16 UTC

Additional testing to show that we can still detect and fail node with local_gb drive =0 by using device hints

This will set the device hints to seek out this case.

for i in `ironic node-list | awk '/None/ {print $2}'`;
do ironic node-update $i add properties/root_device='{"size": "> 1"}';done

follow with introspection
