            <title>[SERVER-81534] DDL locks musn&apos;t be acquired during step down or shutdown</title>
                <link>https://jira.mongodb.org/browse/SERVER-81534</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;The &lt;tt&gt;ShardingDDLCoordinatorService&lt;/tt&gt; blocks the acquisition of DDL locks on step-down to ensure the serialization of DDL operations and other operations that also acquire DDL locks, even with step-downs.&lt;/p&gt;

&lt;p&gt;There are a pair of issues according to this process that should be addressed under this ticket:&lt;/p&gt;

&lt;ul class=&quot;alternate&quot; type=&quot;square&quot;&gt;
	&lt;li&gt;During the step-down, the ShardingDDLCoordinatorService is &lt;a href=&quot;https://github.com/10gen/mongo/blob/3f8d744fb333be9b330e783eff4a02ee24c5faa3/src/mongo/db/repl/primary_only_service.cpp#L530&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;blocking the acquisition of DDL locks&lt;/a&gt; after &lt;a href=&quot;https://github.com/10gen/mongo/blob/3f8d744fb333be9b330e783eff4a02ee24c5faa3/src/mongo/db/repl/primary_only_service.cpp#L523&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;interrupting the DDL operations&lt;/a&gt;. So, there is a small window of time where another operation could kick in and get a DDL lock when it shouldn&apos;t (because another DDL operation may be in progress).&lt;/li&gt;
&lt;/ul&gt;


&lt;ul class=&quot;alternate&quot; type=&quot;square&quot;&gt;
	&lt;li&gt;During the &lt;a href=&quot;https://github.com/10gen/mongo/blob/3f8d744fb333be9b330e783eff4a02ee24c5faa3/src/mongo/db/repl/primary_only_service.cpp#L533&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;shutdown process&lt;/a&gt; is happening something similar but we are even not calling &lt;a href=&quot;https://github.com/10gen/mongo/blob/2c6ae5c16cc92aecd1ae8606b2dd0bbfdf16ebe3/src/mongo/db/s/sharding_ddl_coordinator_service.cpp#L233&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;ShardingDDLCoordinatorService::_afterStepDown()&lt;/a&gt;, which is the method that blocks the DDL lock acquisition.&lt;/li&gt;
&lt;/ul&gt;
