<p>We provide tool(s) to help user get the most out of using the cluster. The tools
described here are organised by use case and include usage examples.</p>

<h3 id="merlin_quotas"><code>merlin_quotas</code><a class="headerlink" href="#merlin_quotas" title="Permanent link"></a></h3>
<p>This tool is available on all of the login nodes and provides a brief overview of
a user's filesystem quotas. These are limits which restrict how much storage (or
number of files) a user can create. A generic table of filesystem quotas can be
found on the <a href="../storage/#dir_classes">Storage page</a>.</p>
<h4 id="example-1-viewing-quotas">Example #1: Viewing quotas<a class="headerlink" href="#example-1-viewing-quotas" title="Permanent link"></a></h4>
<p>Simply calling <code>merlin_quotas</code> will show you a table of our quotas:</p>

<p>As above you can change the table width by pass either <code>--no-wrap</code> or

</div>
<h4 id="example-3-project-config">Example #3: Project config<a class="headerlink" href="#example-3-project-config" title="Permanent link"></a></h4>
<p>To make tracking quotas of projects easier, <code>merlin_quotas</code> generates a config
file in your home directory which defines the projects to show when you call the
tool (called <code>~/.merlin_quotas</code>).</p>
<p>The config file simply contains a list (one per line) of project IDs which should
be tracked. In theory any (or all available projects) can be tracked, but due to
UNIX and Lustre permissions, accessing quotas information for a project you're not
a member of <strong>is not possible</strong>.</p>
<div class="admonition tip">
<p class="admonition-title">Updating the project config</p>
<p>If you are added/removed from a project, you can update this config file by
calling <code>merlin_quotas genconf --all-projects --force</code>. The
<code>--all-projects</code> will fully check your possible membership to all projects,
and the <code>--force</code> will overwrite your existing config file. You can also
edit the file by hand (<em>not recommended</em>).</p>
