Upgrading from Ocata to Pike
|
||||
============================
|
||||
|
||||
#. Use the ``ironic-dbsync online_data_migrations`` command from the 9.1.1 (or
|
||||
newer) release. The one from older (9.0.0 - 9.1.0) releases could cause a
|
||||
a port's physical_network information to be deleted from the database.
|
||||
|
||||
#. It is required to set the ``resource_class`` field for nodes registered
|
||||
with the Bare Metal service *before* using the Pike version of the Compute
|
||||
service. See :ref:`enrollment` for details.
|
||||
|
||||
#. It is recommended to move from old-style classic drivers to the new
|
||||
hardware types after the upgrade to Pike. We expect the classic drivers to
|
||||
be deprecated in the Queens release and removed in the Rocky release.
|
||||
See :doc:`upgrade-to-hardware-types` for the details on the migration.
|
||||
|
||||
Other upgrade instructions are in the `Pike release notes
|
||||
<https://docs.openstack.org/releasenotes/ironic/pike.html>`_.

Upgrading from Kilo to Liberty
|

==============================
|
||||
|
||||
In-band Inspection
|
||||
------------------
|
||||
|
||||
If you used in-band inspection with **ironic-discoverd**, it is highly
|
||||
recommended that you switch to using **ironic-inspector**, which is a newer
|
||||
(and compatible on API level) version of the same service. You have to install
|
||||
**python-ironic-inspector-client** during the upgrade. This package contains a
|
||||
client module for the in-band inspection service, which was previously part of
|
||||
the **ironic-discoverd** package. Ironic Liberty supports the
|
||||
**ironic-discoverd** service, but does not support its in-tree client module.
|
||||
Please refer to
|
||||
:ironic-inspector-doc:`ironic-inspector version support matrix <install/index.html#version-support-matrix>`
|
||||
for details on which ironic versions are compatible with which
|
||||
**ironic-inspector**/**ironic-discoverd** versions.
|
||||
|
||||
The discoverd to inspector upgrade procedure is as follows:
|
||||
|
||||
* Install **ironic-inspector** on the machine where you have
|
||||
**ironic-discoverd** (usually the same as conductor).
|
||||
|
||||
* Update the **ironic-inspector** configuration file to stop using deprecated
|
||||
configuration options, as marked by the comments in the
|
||||
:ironic-inspector-doc:`example.conf <install/index.html#configuration>`.
|
||||
It is recommended you move the configuration file to
|
||||
``/etc/ironic-inspector/inspector.conf``.
|
||||
|
||||
* Shutdown **ironic-discoverd**, and start **ironic-inspector**.
|
||||
|
||||
* During upgrade of each conductor instance:
|
||||
|
||||
#. Shutdown the conductor.
|
||||
#. Uninstall **ironic-discoverd**,
|
||||
install **python-ironic-inspector-client**.
|
||||
#. Update the conductor.
|
||||
#. Update ``ironic.conf`` to use ``[inspector]`` section
|
||||
instead of ``[discoverd]`` (option names are the same).
|
||||
#. Start the conductor.
|
||||

Upgrading from Juno to Kilo
|
||||
===========================
|
||||
|
||||
When upgrading a cloud from Juno to Kilo, users must ensure the nova
|
||||
service is upgraded prior to upgrading the ironic service. Additionally,
|
||||
users need to set a special config flag in nova prior to upgrading to ensure
|
||||
the newer version of nova is not attempting to take advantage of new ironic
|
||||
features until the ironic service has been upgraded. The steps for upgrading
|
||||
your nova and ironic services are as follows:
|
||||
|
||||
- Edit nova.conf and ensure force_config_drive=False is set in the [DEFAULT]
|
||||
group. Restart nova-compute if necessary.
|
||||
- Install new nova code, run database migrations.
|
||||
- Install new python-ironicclient code.
|
||||
- Restart nova services.
|
||||
- Install new ironic code, run database migrations, restart ironic services.
|
||||
- Edit nova.conf and set force_config_drive to your liking, restarting
|
||||
nova-compute if necessary.
|
||||
|
||||
Note that during the period between nova's upgrade and ironic's upgrades,
|
||||
instances can still be provisioned to nodes. However, any attempt by users to
|
||||
specify a config drive for an instance will cause an error until ironic's
|
||||
upgrade has completed.
|
||||
|
||||
Cleaning
|
||||
--------
|
||||
A new feature starting from Kilo cycle is support for the automated cleaning
|
||||
of nodes between workloads to ensure the node is ready for another workload.
|
||||
This can include erasing the hard drives, updating firmware, and other steps.
|
||||
For more information, see :ref:`automated_cleaning`.
|
||||
|
||||
If ironic is configured with automated cleaning enabled (defaults to True) and
|
||||
neutron is set as the DHCP provider (also the default), you will need to set
|
||||
the `cleaning_network_uuid` option in the ironic configuration file before
|
||||
starting the ironic service. See :ref:`configure-cleaning`
|
||||
for information on how to set up the cleaning network for ironic.
