            <title>[SERVER-31025] dbCheck will cause rollback to abort</title>
                <link>https://jira.mongodb.org/browse/SERVER-31025</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;The dbcheck oplog type &lt;a href=&quot;https://github.com/mongodb/mongo/blob/8244b17489f7f6d7daae9920de0fb1ef12e271fc/src/mongo/db/repl/rs_rollback.cpp#L255&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;&lt;tt&gt;OplogEntry::CommandType::kDbCheck&lt;/tt&gt; is currently not supported by rollback&lt;/a&gt;, so attempting to roll back a dbCheck will cause rollback to terminate.&lt;/p&gt;

&lt;p/&gt;

&lt;/div&gt;
&lt;p/&gt;

&lt;p&gt;The correct behavior should be to make dbCheck a no-op during rollback &lt;a href=&quot;https://github.com/mongodb/mongo/blob/8244b17489f7f6d7daae9920de0fb1ef12e271fc/src/mongo/db/repl/rs_rollback.cpp#L421-L438&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;similar to dropDatabase&lt;/a&gt;, as dbCheck commands do not need to be rolled back.&lt;/p&gt;</description>

For backporting to 4.4, we should refuse to run dbCheck in that configuration since durable history is available and makes EMRC=off unnecessary. &lt;/p&gt;</comment>
