            <title>[SERVER-31596] recovery messages always appear in the log, even after clean shutdown</title>
                <link>https://jira.mongodb.org/browse/SERVER-31596</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;If I shut down a mongod cleanly and restart it, I always see these messages appear in the log:&lt;/p&gt;
&lt;p/&gt;

&lt;/table&gt;
&lt;/div&gt;
&lt;p/&gt;
&lt;p&gt;(I noticed them appearing in our jstest output.)&lt;br/&gt;
Is this expected?  Something may have changed recently to cause the &quot;17 through 18&quot; message to always appear.  The original ticket that turned on verbosity was &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-16796&quot; title=&quot;Increase logging activity for journal recovery operations&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-16796&quot;&gt;&lt;del&gt;SERVER-16796&lt;/del&gt;&lt;/a&gt;, but I don&apos;t think the messages appeared back then; something changed more recently.&lt;/p&gt;</description>

                            <comment id="1703041" author="sue.loverso" created="Wed, 18 Oct 2017 19:18:40 +0000"  >&lt;p&gt;The configuration to turn it on in MongoDB was added in Jan: &lt;a href=&quot;https://github.com/mongodb/mongo/commit/9ef439f18536ec11af418602880359438ab84c64&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;https://github.com/mongodb/mongo/commit/9ef439f18536ec11af418602880359438ab84c64&lt;/a&gt; &lt;br/&gt;
and it was not backported to 3.4, even though the WiredTiger changes supporting it were backported.  The messages appear anytime the &lt;tt&gt;verbose=(recovery_progress)&lt;/tt&gt; setting is turned on.  If I add that to the mongod command line in 3.4 with &lt;tt&gt;--wiredTigerEngineConfigString=&apos;,verbose=(recovery_progress)&apos;&lt;/tt&gt; then I see them there too on restart after a clean shutdown.&lt;/p&gt;

&lt;p&gt;WiredTiger recovery is run on every startup.  A clean shutdown allows us to skip the full checkpoint that recovery forces, but we do go through the WT log.  In the case of clean shutdown, when we checkpoint on close, that should be really, really fast as we have nothing to apply.&lt;/p&gt;</comment>
