Unused by Nova and unlike memory_mb/local_gb also by Ironic (actually, our usage of local_gb is worth double-checking as well, but at the very least it's referenced by inspection implementations). Change-Id: Ie8b0d9f58f4dcd102c183c30ae7f5acf68a5e4c3

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::
|
|
|
|

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.
|
|
::
|
|
|
|
$ baremetal node maintenance set $NODE_UUID
|
|
|
|
A 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.
|
|
|
|
::
|
|
|
|
$ baremetal node maintenance set $UUID --reason "Need to add ram."
|
|
|
|
$ baremetal node show $UUID
|

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