Placement microversion 1.35 gives us the root_required queryparam to GET /allocation_candidates, allowing us to filter out candidates where the *root* provider has/lacks certain traits, independent of traits specified in any of the individual request groups. Use it. And add affordance for specifying such traits to the RequestSpec. Which allows us to fix up the couple of request filters that were hacking traits into the RequestSpec.flavor.

Description
|
|
===========
|
|
|
|
:program:`nova-status` is a tool that provides routines for checking the status
|
|
of a Nova deployment.
|
|
|
|

|
|
=======
|
|
|
|
The standard pattern for executing a :program:`nova-status` command is::
|
|
|
|
nova-status <category> <command> [<args>]
|
|
|
|
Run without arguments to see a list of available command categories::
|
|
|
|
nova-status
|
|
|
|
Categories are:
|
|
|
|
* ``upgrade``
|
|
|
|
Detailed descriptions are below.
|
|
|
|
You can also run with a category argument such as ``upgrade`` to see a list of
|
|
all commands in that category::
|
|
|
|
nova-status upgrade
|
|
|
|
These sections describe the available categories and arguments for
|
|
:program:`nova-status`.
|
|
|
|
Upgrade
|
|
~~~~~~~
|
|
|
|
.. _nova-status-checks:
|
|
|
|
``nova-status upgrade check``
|
|
Performs a release-specific readiness check before restarting services with
|
|
new code. This command expects to have complete configuration and access
|
|
to databases and services within a cell. For example, this check may query
|
|
the Nova API database and one or more cell databases. It may also make
|
|
requests to other services such as the Placement REST API via the Keystone
|
|
service catalog.

- Description
|
|
* - 0
|
|
- All upgrade readiness checks passed successfully and there is nothing
|
|
to do.
|
|
* - 1
|
|
- At least one check encountered an issue and requires further
|
|
investigation. This is considered a warning but the upgrade may be OK.
|
|
* - 2
|
|
- There was an upgrade status check failure that needs to be
|
|
investigated. This should be considered something that stops an
|
|
upgrade.
|
|
* - 255
|
|
- An unexpected error occurred.

|
**History of Checks**
|
|
|
|
**15.0.0 (Ocata)**
|
|
|
|
* Checks are added for cells v2 so ``nova-status upgrade check`` should be
|
|
run *after* running the ``nova-manage cell_v2 simple_cell_setup``
|
|
command.
|
|
* Checks are added for the Placement API such that there is an endpoint in
|
|
the Keystone service catalog, the service is running and the check can
|
|
make a successful request to the endpoint. The command also checks to
|
|
see that there are compute node resource providers checking in with the
|
|
Placement service. More information on the Placement service can be found
|
|
at :placement-doc:`Placement API <>`.
|
|
|
|
**16.0.0 (Pike)**
|
|
|
|
* Checks for the Placement API are modified to require version 1.4, that
|
|
is needed in Pike and further for nova-scheduler to work correctly.
|
|
|
|
**17.0.0 (Queens)**
|
|
|
|
* Checks for the Placement API are modified to require version 1.17.
|
|
|
|
**18.0.0 (Rocky)**
|
|
|
|
* Checks for the Placement API are modified to require version 1.28.
|
|
* Checks that ironic instances have had their embedded flavors migrated to
|
|
use custom resource classes.
|
|
* Checks for ``nova-osapi_compute`` service versions that are less than 15
|
|
across all cell mappings which might cause issues when querying instances
|
|
depending on how the **nova-api** service is configured.
|
|
See https://bugs.launchpad.net/nova/+bug/1759316 for details.
|
|
* Checks that existing instances have been migrated to have a matching
|
|
request spec in the API DB.
|
|
|
|
**19.0.0 (Stein)**
|
|
|
|
* Checks for the Placement API are modified to require version 1.30.
|
|
* Checks are added for the **nova-consoleauth** service to warn and provide
|
|
additional instructions to set **[workarounds]enable_consoleauth = True**
|
|
while performing a live/rolling upgrade.
|
|
* The "Resource Providers" upgrade check was removed since the placement
|
|
service code is being extracted from nova and the related tables are no
|
|
longer used in the ``nova_api`` database.
|
|
* The "API Service Version" upgrade check was removed since the corresponding
|
|
code for that check was removed in Stein.
|
|
|
|
**20.0.0 (Train)**
|
|
|
|
* Checks for the Placement API are modified to require version 1.32.
|
|
* Checks to ensure block-storage (cinder) API version 3.44 is
|
|
available in order to support multi-attach volumes.
|
|
If ``[cinder]/auth_type`` is not configured this is a no-op check.
|
|
* The "**nova-consoleauth** service" upgrade check was removed since the
|
|
service was removed in Train.
|
|
* The ``Request Spec Migration`` check was removed.
|
|
|
|
**21.0.0 (Ussuri)**
|
|
* Checks for the Placement API are modified to require version 1.35.
