<p>I have my <code>rook-ceph</code>cluster running on <code>AWS</code>. Its loaded up with data.
Is there's any way to stimulate <strong>POWER FAILURE</strong>  so that I can test the behaviour of my cluster?.</p>

<p>From Docker you can send KILL signal "SIGPWR" that <a href="http://man7.org/linux/man-pages/man7/signal.7.html" rel="nofollow noreferrer">Power failure (System V)</a></p>

<pre><code>docker kill --signal="SIGPWR"
</code></pre>

<p>and from Kubernet</p>

<pre><code>kubectl exec &lt;pod&gt; -- /killme.sh
</code></pre>

<p>and so scriplt killme.sh</p>

<pre><code>beginning of script-----
#!/bin/bash
# Define process to find
kiperf=$(pidof iperf)
# Kills all iperf or command line
kill -30 $kiperf
script end -------------
</code></pre>

<p>signal 30 you can find <a href="https://www.linuxsecrets.com/1676-simple-way-to-kill-a-pid-processid-from-cli-or-a-bash-script" rel="nofollow noreferrer">here</a></p>
