===========
|
|
|
|
: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 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.
|

**Return Codes**
|
|
|
|
.. list-table::

|
|
* - Return code
|
|
- 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 :nova-doc:`user/placement.html>`.
|
|
|
|
**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 1.24.
|
|
* 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.
