features in more detail.</p> <h2>Openstack Liberty deployment</h2> <p>–(Autopilot in LDS 15.11 will deploy Openstack Liberty clouds.)-- Due to <a href="https://bugs.launchpad.net/ubuntu/+source/nova/+bug/1559935">https://bugs.launchpad.net/ubuntu/+source/nova/+bug/1559935</a>, please use a newer version of Landscape if you want to use the Autopilot. In particular, version 16.03.1 at the time of this writing is the preferred way to deploy OpenStack Liberty.</p> <h2>MAAS supported version</h2> <p>Autopilot in LDS 15.11 supports MAAS 1.8.x only.</p> <h1>Upgrade notes</h1> <p>LDS 15.11 supports Ubuntu 14.04 LTS (“trusty”). It can only be upgraded from LDS 15.10.X or an earlier version in the 15.11 series.</p> <h2>Quickstart upgrade</h2> <p>If you used the landscape-server-quickstart package to install LDS 15.10.X or an earlier LDS 15.11 then you can use this method to upgrade it.</p> <p>If you are a <a href="https://landscape.canonical.com">https://landscape.canonical.com</a> customer, you can select new version of LDS in your hosted account at <a href="https://landscape.canonical.com">https://landscape.canonical.com</a> and then run:</p> <pre><code class="lang-nohighlight"> sudo apt-get update sudo apt-get dist-upgrade </code></pre> <p>Alternatively, just add the LDS 15.11 PPA and run the same commands as above:</p> <pre><code class="lang-nohighlight"> sudo add-apt-repository ppa:landscape/15.11 sudo apt-get update sudo apt-get dist-upgrade </code></pre> <p>When prompted, reply with N to any dpkg questions about configuration files so the existing files stay untouched. The quickstart package will make any needed modifications to your configuration files automatically.</p> <h2>Non-quickstart upgrade</h2> <p>Follow these steps to perform a non-quickstart upgrade, that is, you did not use the landscape-server-quickstart package when installing LDS 15.10.X or an earlier LDS 15.11:</p> <ul> <li>stop all landscape services on all machines that make up your non-quickstart deployment, except the database service: <code>sudo lsctl stop</code> </li> <li>add the LDS 15.11 PPA: <code>sudo add-apt-repository ppa:landscape/15.11</code> </li> <li>refresh the apt database and upgrade: <code>sudo apt-get update && sudo apt-get dist-upgrade</code> </li> <li>answer with “N” to any dpkg questions about Landscape configuration files</li> <li>if you have <code>UPGRADE_SCHEMA</code> enabled in <code>/etc/default/landscape-server</code>, then the required schema upgrade will be performed as part of the package upgrade and all services will be running at the end. The upgrade is finished.</li> <li>if <code>UPGRADE_SCHEMA</code> is disabled, then you will have failures when the services are restarted at the end of the upgrade. That’s expected. You now have to perform the schema upgrade manually with this command:</li> </ul> <pre><code class="lang-nohighlight"> sudo setup-landscape-server </code></pre> <p>after it succeeds, the Landscape services can be started:</p> <pre><code class="lang-nohighlight"> sudo lsctl start </code></pre> <h2>Upgrading a Juju deployed LDS</h2> <p>Starting with LDS 15.10, juju deployed LDS can be upgraded in place. Please follow this procedure:</p> <pre><code class="lang-nohighlight">juju upgrade-charm landscape-server juju set landscape-server source=ppa:landscape/15.11 juju action do landscape-server/0 pause juju action do landscape-server/0 upgrade juju action do landscape-server/0 migrate-schema juju action do landscape-server/0 resume </code></pre> <p>Each action returns an identifier that should be used to check its outcome with the fetch command before running the next action:</p> <pre><code class="lang-nohighlight">juju action fetch <uuid> </code></pre> <p>For example:</p> <pre><code class="lang-nohighlight">$ juju action do landscape-server/0 pause Action queued with id: 72fd7975-3e0b-4b6d-84b9-dbd76d50f6af $ juju action fetch 72fd7975-3e0b-4b6d-84b9-dbd76d50f6af status: completed timing: completed: 2015-06-23 19:24:39 +0000 UTC enqueued: 2015-06-23 19:24:32 +0000 UTC started: 2015-06-23 19:24:33 +0000 UTC </code></pre> <p>As an example of when it fails, here we are trying to upgrade a unit that hasn’t been paused before:</p> <pre><code class="lang-nohighlight">$ juju action do landscape-server/0 upgrade Action queued with id: f3d2343c-33e4-4faf-8c4e-59f796124dd4 $ juju action fetch f3d2343c-33e4-4faf-8c4e-59f796124dd4 message: This action can only be called on a unit in paused state. status: failed timing: completed: 2015-06-23 19:26:40 +0000 UTC enqueued: 2015-06-23 19:26:36 +0000 UTC started: 2015-06-23 19:26:38 +0000 UTC </code></pre> <h1>Known Issues</h1> <p>This section describes important known issues with this release.</p> <h2>Autopilot Cloud Deployments</h2> <p>Due to a version change in keystone (<a href="https://bugs.launchpad.net/ubuntu/+source/nova/+bug/1559935">https://bugs.launchpad.net/ubuntu/+source/nova/+bug/1559935</a>), a component of OpenStack, this release of the Autopilot cannot deploy OpenStack Liberty clouds anymore.
