Quota class sets (os-quota-class-sets)
|
|
=======================================
|
|
|
|
Show, Create or Update the quotas for a Quota Class.
|
|
Nova supports implicit 'default' Quota Class only.
|
|
|
|
.. note::
|
|
Once a default limit is set via the ``default`` quota class via the API,
|
|
that takes precedence over any changes to that resource limit in the
|
|
configuration options. In other words, once you've changed things via
|
|
the API, you either have to keep those synchronized with the configuration
|
|
values or remove the default limit from the database manually as there is
|
|
no REST API for removing quota class values from the database.
|
|
|
|
For Example: If you updated default quotas for instances, to 20, but
|
|
didn't change ``quota_instances`` in your ``nova.conf``, you'd now
|
|
have default quota for instances as 20 for all projects.
|
|
If you then change ``quota_instances=5`` in nova.conf, but didn't
|
|
update the ``default`` quota class via the API, you'll still have
|
|
a default quota of 20 for instances regardless of ``nova.conf``.
|
|
Refer: `Quotas
|
|
<https://docs.openstack.org/nova/latest/user/quotas.html>`__
|
|
for more details.
|
|
|
|
.. warning::
|
|
There is a bug in the v2.1 API until microversion 2.49 and
|
|
the legacy v2 compatible API which does not return the
|
|
``server_groups`` and ``server_group_members`` quotas in
|
|
GET and PUT ``os-quota-class-sets`` API response, whereas the v2 API
|
|
used to return those keys in the API response.
|
|
There is workaround to get the ``server_groups`` and
|
|
``server_group_members`` quotas using
|
|
"List Default Quotas For Tenant" API in :ref:`os-quota-sets`
|
|
but that is per project quota.
|
|
This issue is fixed in microversion 2.50, here onwards
|
|
``server_groups`` and ``server_group_members`` keys are
|
|
returned in API response body.
