            <title>[SERVER-71399] Jumbo chunk flag isn&apos;t automatically cleared after a chunk split</title>
                <link>https://jira.mongodb.org/browse/SERVER-71399</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Regading the &lt;a href=&quot;https://www.mongodb.com/docs/manual/tutorial/clear-jumbo-flag/#:~:text=MongoDB%20removes%20the%20jumbo%20flag%20upon%20successful%20split%20of%20the%20chunk&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;MongoDB documentation about jumbo chunks&lt;/a&gt;, MongoDB removes the jumbo flag upon successful split of the chunk. That&apos;s not the actual behaviour, though.&lt;/p&gt;

&lt;p&gt;The current behaviour is that after a successful split of a jumbo chunk we get 2 new jumbo chunks because &lt;a href=&quot;https://github.com/10gen/mongo/blob/492a1bc089229e25595aee837ee2f38e4c00eba6/src/mongo/db/s/config/sharding_catalog_manager_chunk_operations.cpp#L576&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;new chunks are initialised as a copy of the original chunk&lt;/a&gt;.&lt;/p&gt;

&lt;p&gt;Since there is no test controlling that, the scope of this ticket should also include a test case to cover that scenario.&lt;br/&gt;
You will find attached to this ticket a brand new test file to force the issue. It must be run on the &lt;tt&gt;sharding&lt;/tt&gt; suite.&lt;/p&gt;</description>
