            <title>[SERVER-63722] Rename collection participants get stuck upon errors different from stepdown/shutdown</title>
                <link>https://jira.mongodb.org/browse/SERVER-63722</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;By design, it was assumed that rename collection participants could only fail due to stepdown/shutdown errors, so the rationale was: &lt;a href=&quot;https://github.com/mongodb/mongo/blob/4f5e36cf646ba361e3c92e4e98eab36c6c0474f3/src/mongo/db/s/rename_collection_participant_service.h#L170-L181&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;promises&lt;/a&gt; would be &lt;a href=&quot;https://github.com/mongodb/mongo/blob/4f5e36cf646ba361e3c92e4e98eab36c6c0474f3/src/mongo/db/s/rename_collection_participant_service.cpp#L228-L241&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;invalidated&lt;/a&gt; before releasing POS instances and eventually new primaries would resume such instances with a clean state.&lt;/p&gt;

&lt;p&gt;However, it turns out that there are some scenarios in which &quot;non-stepdown&quot; recoverable errors can happen, meaning that promises get invalidated but POS participant instances do not get released. As a consequence, any retry results in the following flow: get the POS instance, check the promises and fail again.&lt;/p&gt;

&lt;p&gt;This can happen for example in case of index builds happening concurrently on a collection being renamed (participants get stuck with &lt;tt&gt;BackgroundOperationInProgressForNamespace&lt;/tt&gt; error).&lt;/p&gt;

&lt;p&gt;&#8212;&lt;/p&gt;

&lt;p&gt;&lt;font color=&quot;#de350b&quot;&gt;&lt;b&gt;Workaround&lt;/b&gt;&lt;/font&gt; in case this bug is hit by some users: trigger an election on all shards with a stuck rename participant.&lt;/p&gt;</description>
