Parts of the compute REST API are now relying on getting information from
|
|
cells via their mappings in the ``nova_api`` database. This is to support
|
|
multiple cells. For example, when listing compute hosts or services, all
|
|
cells will be iterated in the API and the results will be returned.
|
|
|
|
This change can have impacts, however, to deployment tooling that relies on
|
|
parts of the API, like listing compute hosts, `before` the compute hosts
|
|
are mapped using the ``nova-manage cell_v2 discover_hosts`` command.
|
|
|
|
If you were using ``nova hypervisor-list`` after starting new nova-compute
|
|
services to tell when to run ``nova-manage cell_v2 discover_hosts``, you
|
|
should change your tooling to instead use one of the following commands::
|
|
|
|
nova service-list --binary nova-compute [--host <hostname>]
|
|
|
|
openstack compute service list --service nova-compute [--host <host>]
|
|
|
|
As a reminder, there is also the
|
|
``[scheduler]/discover_hosts_in_cells_interval`` configuration option which
|
|
can be used to automatically discover hosts from the nova-scheduler
|
|
service. |
