Cluster running. Preparing your cluster configuration is fairly
straightforward; all a DRBD-based Red Hat Cluster requires are two
participating nodes (referred to as <span class="emphasis"><em>Cluster Members</em></span> in Red Hat’s
documentation) and a fencing device.</p><div class="note" style="margin-left: 0.5in; margin-right: 0.5in;"><table border="0" summary="Note"><tr><td rowspan="2" align="center" valign="top" width="25"><img alt="[Note]" src="images/note.png" /></td><th align="left">Note</th></tr><tr><td align="left" valign="top"><p>For more information about configuring Red Hat clusters, see

<a id="idp46395648" class="indexterm"></a><a id="idp46396528" class="indexterm"></a><code class="literal">/etc/cluster/cluster.conf</code>. You may manage your
cluster configuration in the following ways:</p><p><strong>Editing the configuration file directly. </strong>This is the most straightforward method. It has no prerequisites other
than having a text editor available.</p><p><strong>Using the <code class="literal">system-config-cluster</code> GUI. </strong>This is a GUI application written in Python using Glade. It requires
the availability of an X display (either directly on a server console,
or tunneled via SSH).</p><p><strong>Using the Conga web-based management infrastructure. </strong>The Conga infrastructure consists of a node agent ( <code class="literal">ricci</code>)
communicating with the local cluster manager, cluster resource
manager, and cluster LVM daemon, and an administration web application
( <code class="literal">luci</code>) which may be used to configure the cluster infrastructure
using a simple web browser.</p></div></div><div class="navfooter"><hr /><table width="100%" summary="Navigation footer"><tr><td width="40%" align="left"><a accesskey="p" href="ch-rhcs.html">Prev</a> </td><td width="20%" align="center"><a accesskey="u" href="ch-rhcs.html">Up</a></td><td width="40%" align="right"> <a accesskey="n" href="s-rhcs-failover-clusters.html">Next</a></td></tr><tr><td width="40%" align="left" valign="top">Chapter 9. Integrating DRBD with Red Hat Cluster </td><td width="20%" align="center"><a accesskey="h" href="drbd-users-guide.html">Home</a></td><td width="40%" align="right" valign="top"> 9.3. Using DRBD in Red Hat Cluster fail-over clusters</td></tr></table></div></body></html>
