&lt;p&gt;    New clearJumboChunk command for clearing jumbo flag in chunks&lt;/p&gt;
&lt;/div&gt;&lt;/div&gt;

&lt;p&gt;    Currently the steps to &lt;a href=&quot;https://docs.mongodb.com/manual/tutorial/clear-jumbo-flag/#indivisible-chunks&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;clear the jumbo flag&lt;/a&gt; for a chunk is quite complicated, prone to user error, and requires modifying the config database. It would be nice to support a &lt;tt&gt;clearJumboChunk&lt;/tt&gt; command on the mongos, which goes through the proper versioning protocol and doesn&apos;t require direct access to the config servers.&lt;/p&gt;

                            <comment id="2478471" author="renctan" created="Fri, 11 Oct 2019 18:51:59 +0000"  >&lt;p&gt;The command has very similar api to moveChunk to specify the chunk you want to clear. Example usage for range-based shard keys:&lt;/p&gt;

&lt;p&gt;&lt;a href=&quot;https://github.com/mongodb/mongo/blob/a3e787c2a1051c0787af09a700a872a1271b491e/jstests/sharding/clear_jumbo.js#L30&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;https://github.com/mongodb/mongo/blob/a3e787c2a1051c0787af09a700a872a1271b491e/jstests/sharding/clear_jumbo.js#L30&lt;/a&gt;&lt;/p&gt;

&lt;p&gt;Example for hashed-based shard keys:&lt;/p&gt;

&lt;p&gt;&lt;a href=&quot;https://github.com/mongodb/mongo/blob/a3e787c2a1051c0787af09a700a872a1271b491e/jstests/sharding/clear_jumbo.js#L54&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;https://github.com/mongodb/mongo/blob/a3e787c2a1051c0787af09a700a872a1271b491e/jstests/sharding/clear_jumbo.js#L54&lt;/a&gt;&lt;/p&gt;

&lt;p&gt;Requires clearJumboFlag action type:&lt;br/&gt;
&lt;a href=&quot;https://github.com/mongodb/mongo/blob/a3e787c2a1051c0787af09a700a872a1271b491e/src/mongo/db/auth/role_graph_builtin_roles.cpp#L251&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;https://github.com/mongodb/mongo/blob/a3e787c2a1051c0787af09a700a872a1271b491e/src/mongo/db/auth/role_graph_builtin_roles.cpp#L251&lt;/a&gt;&lt;/p&gt;

&lt;p&gt;which is added to the clusterManager role by default.&lt;/p&gt;</comment>
