            <title>[SERVER-14725] In 2.6, mongod does not resume writing to the log file when the disk for the log volume is full, and then the space is free up</title>
                <link>https://jira.mongodb.org/browse/SERVER-14725</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;The log files are saved on a different volume than the data and journals.&lt;/p&gt;

&lt;p&gt;In 2.6, when the log volume is full, it stop writing to the log file. However, when we free the disk space, it does &lt;b&gt;not&lt;/b&gt; write to the log file any more. We have to run logrotate command will trigger it to continue writing to the log file. This is different than 2.2/2.4.&lt;/p&gt;

&lt;p&gt;In 2.2 and 2.4, when the log volume is full, it also stops writing to the log file. When we free the disk space, it would &lt;b&gt;continue&lt;/b&gt; writing to the log file like this:&lt;/p&gt;

                            <comment id="3049437" author="milkie" created="Tue, 21 Apr 2020 17:26:38 +0000"  >&lt;p&gt;To clarify, the shut down that Sara mentions will be an unclean shutdown (no final checkpoint taken), and the act of shutting down itself will be &quot;in the dark&quot; since it will be impossible to log a message about it.  But no other unlogged actions should occur besides the shutdown itself.&lt;/p&gt;</comment>
                            <comment id="3049183" author="sara.golemon" created="Tue, 21 Apr 2020 15:09:29 +0000"  >&lt;p&gt;The current logging subsystem will now shut down a node with a full log filesystem rather than carry on processing unlogged requests.&#160; This makes the subject of resumability rather moot.&lt;/p&gt;

&lt;p&gt;This isn&apos;t quite what this ticket is asking for, but is arguably the better action to take by default so that no actions are taken &quot;in the dark&quot;.&lt;/p&gt;</comment>

The first time I run &lt;tt&gt;logRotate&lt;/tt&gt; the &lt;tt&gt;mongod.log&lt;/tt&gt; file is rotated and a new one is created, but if the filesystem is still full &lt;tt&gt;mongod&lt;/tt&gt; still won&apos;t log anything. After I move the rotated log file to some other filesystem to make some space, doing a second &lt;tt&gt;logRotate&lt;/tt&gt; allows &lt;tt&gt;mongod&lt;/tt&gt; to resume logging.&lt;/p&gt;
