            <title>[DOCS-10928] Replica set nodes running with --nojournal should have writeConcernMajorityJournalDefault set to false.</title>
                <link>https://jira.mongodb.org/browse/DOCS-10928</link>
                <project id="10380" key="DOCS">Documentation</project>
                    <description>&lt;p&gt;If a replica set is running without journaling, the &lt;b&gt;writeConcernMajorityJournalDefault&lt;/b&gt; option in the replica set config should be set to false.&lt;/p&gt;

&lt;p&gt;If this isn&apos;t done there will be multiple issues, including:&lt;/p&gt;
&lt;ul&gt;
	&lt;li&gt;w:majority writes will never complete&lt;/li&gt;
	&lt;li&gt;two-phase collection drops will never actually drop the underlying WT tables.&lt;/li&gt;
&lt;/ul&gt;


&lt;p&gt;This update should also be backported to &lt;b&gt;v3.4&lt;/b&gt; and &lt;b&gt;v3.2&lt;/b&gt;.&lt;/p&gt;

                            <comment id="1729488" author="steve.renaker" created="Sat, 18 Nov 2017 00:13:36 +0000"  >&lt;p&gt;We have a documented recommendation that users &lt;b&gt;not&lt;/b&gt; run replica sets on WT with journaling turned off, per &lt;a href=&quot;https://jira.mongodb.org/browse/DOCS-10925&quot; class=&quot;external-link&quot; rel=&quot;nofollow&quot;&gt;https://jira.mongodb.org/browse/DOCS-10925&lt;/a&gt;. The --nojournal option is deprecated on 3.6 for replica sets with WT.&lt;/p&gt;

&lt;p&gt;We could modify that recommendation to something like &quot;You really shouldn&apos;t do this, but if you absolutely must, then you should also set writeConcernMajorityJournalDefault to false.&quot; But it seems better to keep the recommendation to a simple &quot;don&apos;t do it.&quot;&lt;/p&gt;

&lt;p&gt;I&apos;m proposing to add the information about writeConcernMajorityJournalDefault to the 3.4 and 3.2 docs but leave it out of the 3.6 docs.&lt;/p&gt;</comment>
