Troubleshooting
Once all the services are running and configured properly, and a node
has been enrolled with the Bare Metal service and is in the
available provision state, the Compute service should
detect the node as an available resource and expose it to the
scheduler.
Note
There is a delay, and it may take up to a minute (one periodic task cycle) for the Compute service to recognize any changes in the Bare Metal service's resources (both additions and deletions).
In addition to watching nova-compute log files, you can
see the available resources by looking at the list of Compute
hypervisors. The resources reported therein should match the bare metal
node properties, and the Compute service flavor.
Here is an example set of commands to compare the resources in Compute service and Bare Metal service:
$ openstack baremetal node list

+-------------------------+--------------------------------------+Maintenance mode
Maintenance mode may be used if you need to take a node out of the resource pool. Putting a node in maintenance mode will prevent Bare Metal service from executing periodic tasks associated with the node. This will also prevent Compute service from placing a tenant instance on the node by not exposing the node to the nova scheduler. Nodes can be placed into maintenance mode with the following command. :
$ openstack baremetal node maintenance set $NODE_UUIDA maintenance reason may be included with the optional
--reason command line option. This is a free form text
field that will be displayed in the maintenance_reason
section of the node show command.
$ openstack baremetal node maintenance set $UUID --reason "Need to add ram."
$ openstack baremetal node show $UUID

| maintenance | True |

+------------------------+--------------------------------------+To remove maintenance mode and clear any
maintenance_reason use the following command. :
$ openstack baremetal node maintenance unset $NODE_UUID
