<h1>Frequently Asked Questions</h1>
</header>
<p class="question">Q: Where can I get Pacemaker?</p>
<p class="answer">A: Pacemaker ships as part of most common Linux
distributions, including CentOS, Debian, Fedora, Gentoo, OpenSUSE,
Red Hat Enterpise Linux, SUSE Linux Enterprise Server, Ubuntu, and
their derivatives, so you can usually just launch your favorite
package manager.
</p>
<p class="answer">
If all else fails, you can try installing from <a
href="https://github.com/ClusterLabs/pacemaker">source</a>.
</p>
<p class="question">Q: Is there any documentation?</p>
<p class="answer">A: Yes. You can find the set relevant to
your version in our <a href="/doc">documentation
index</a>.
</p>
<p class="question">Q: Where should I ask questions?</p>
<p class="answer">A: The ClusterLabs
<a href="https://lists.clusterlabs.org/mailman/listinfo/">mailing lists</a>
are usually the best place, as there is an active community with a wide
range of experience, and the answers will be archived to benefit
all users. There is also the
- <a href="irc://irc.freenode.org#clusterlabs">#clusterlabs IRC channel on freenode</a>
+ <a href="irc://irc.libera.chat/#clusterlabs">#clusterlabs IRC channel on Libera</a>
for more immediate gratification, though with fewer participants.
</p>
<p class="question">Q: What kind of applications can I manage with Pacemaker?</p>
<p class="answer">A: Pacemaker has no direct intelligence about
specific services. Instead, it relies on resource agents, which are
small applications (often shell scripts) that provide a
standardized, generic interface to particular services. This means
that any service can be made highly available, using a script
conforming to one of the supported standards:
<a href="http://refspecs.linuxbase.org/LSB_3.0.0/LSB-PDA/LSB-PDA/iniscrptact.html">LSB ("init scripts")</a>,
<a href="https://github.com/ClusterLabs/OCF-spec/tree/master/ra">OCF resource agents</a>,
and depending on the environment and options selected when
Pacemaker was built, systemd units, upstart, and
<a href="http://nagios-plugins.org/doc/guidelines.html">Nagios Plugins</a>.
The ClusterLabs <a href="https://github.com/ClusterLabs/resource-agents">resource-agents</a>
project provides a set of OCF agents for common services, and other
projects provide additional agents.
</p>
<p class="question">Q: Do I need shared storage?</p>
<p class="answer">A: No. Pacemaker can manage shared storage, and
there are fencing techniques that can utilize shared storage,
but Pacemaker itself does not require it.
</p>
<p class="question">Q: Which cluster filesystems does Pacemaker support?</p>
<p class="answer">A: Pacemaker can support any filesystem with an appropriate
resource agent. The resource-agents project provides agents for
<a href="https://en.wikipedia.org/wiki/OCFS2">OCFS2</a>
and <a href="https://en.wikipedia.org/wiki/GFS2">GFS2</a>.
You can use these cluster filesystems with physical disks or
network block devices such as
<a href="https://en.wikipedia.org/wiki/Distributed_Replicated_Block_Device">DRBD</a>.
</p>
<p class="question">Q: What does Pacemaker use for cluster quorum and communication?</p>
<p class="answer">A: Pacemaker relies on external software for
cluster formation. Pacemaker 2.0.0 and above supports only Corosync
version 2.0 or above for this purpose. Older Pacemaker versions
additionally supported <a href="http://linux-ha.org/wiki/Heartbeat">Heartbeat</a>
and Corosync 1 with either CMAN or the Pacemaker plugin.</p>
<p class="question">Q: Does my cluster need fencing?</p>
<p class="answer">A: Yes.</p>
<p class="question">Q: No, really, isn't fencing optional?</p>
<p class="answer">A: Fencing is the only way to recover from certain
failure scenarios and ensure the integrity of your data by avoiding
a "split-brain" situation. Although Pacemaker is technically able
to function without fencing, organizations that provide commercial
support generally require it, for good reason.
</p>
<p class="question">Q: How is Pacemaker configured?</p>
<p class="answer">A: Pacemaker uses XML as its native configuration
format, but users do not have to deal with XML directly. Pacemaker
provides low-level command-line tools for common tasks, and other
projects provide more user-friendly, high-level
<a href="components.html#addons">command-line and graphical user interfaces</a>.
</p>
<p class="question">Q: How do I synchronize the cluster configuration?</p>
<p class="answer">A: Any changes to Pacemaker's
configuration are automatically replicated to other
machines. The configuration is also versioned, so any
offline machines will be updated when they return.
</p>
<p class="question">Q: Should I choose pcs or the crm shell as a high-level interface?</p>
<p class="answer">A: Arguably the best advice is to use
whichever one comes with your distro. This is the one
that will be tailored to that environment, receive regular
bugfixes and feature in the documentation.
</p>
<p class="answer">
Of course, if you have a strong preference, you can build your
favorite configuration tool from source if your distro doesn't ship
it.
</p>
<p class="question">Q: What if my question isn't here?</p>
<p class="answer">A: See the <a href="help.html">getting help</a> section and let us know!</p>

<h1>Getting Help</h1>
</header>
<p>
A good first step is always to check out
the <a href="/faq.html">FAQ</a>
and <a href="/pacemaker/doc/">documentation</a>. Otherwise, many
members of the community hang out
- on <a href="irc://irc.freenode.org#clusterlabs">irc</a>
+ on <a href="irc://irc.libera.chat/#clusterlabs">IRC</a>
and are happy to answer questions. We are spread out over
many timezones though (and have day jobs), so you may need
to be patient when waiting for a reply.
</p>
<p>
Extended or complex issues might be better sent to the
relevant <a href="https://wiki.clusterlabs.org/wiki/Mailing_lists">mailing list</a>
(you'll need to subscribe in order to send messages).
</p>
<p>
People new to the project, or Open Source generally, are
encouraged to
read <a href="http://www.mikeash.com/getting_answers.html">Getting
Answers</a> by Mike Ash from Rogue Amoeba. It provides
some very good tips on effective communication with groups
such as this one. Following the advice it contains will
greatly increase the chance of a quick and helpful reply.
</p>
<p>Bugs and other problems can also be reported
via <a href="https://bugs.clusterlabs.org/">Bugzilla</a>.
</p>
<p>
Or if you already know the
solution, <a href="https://help.github.com/articles/using-pull-requests">submit
a patch</a> against
our <a href="https://github.com/ClusterLabs/pacemaker">GitHub
repository</a>.
</p>
<p>
The development of most of the ClusterLabs-related projects take place as part of
the <a href="https://github.com/ClusterLabs/">ClusterLabs</a> organization at Github,
and the source code and issue trackers for these projects can be found there.
