            <title>[SERVER-31922] Make the migration chunk cloner source resilient to stepdowns and network errors</title>
                <link>https://jira.mongodb.org/browse/SERVER-31922</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;On the donor shard, the MigrationChunkClonerSourceLegacy::startClone code uses &lt;a href=&quot;https://github.com/mongodb/mongo/blob/e977f79fb37f7c6608bcfa7df81932b302285a57/src/mongo/db/s/migration_chunk_cloner_source_legacy.cpp#L228-L231&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;_callRecipient&lt;/a&gt; private class function to call the recipient, which then uses the &lt;a href=&quot;https://github.com/mongodb/mongo/blob/e977f79fb37f7c6608bcfa7df81932b302285a57/src/mongo/db/s/migration_chunk_cloner_source_legacy.cpp#L540-L545&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;task executor to make the call&lt;/a&gt;. The task executor does not retry NotMaster errors.&lt;/p&gt;

&lt;p&gt;A solution would be to use a ShardRemote, instead, and allow NotMaster errors to be retried for that first command, _recvChunkStart &amp;#8211; don&apos;t want to use it for all commands, but the first one is safe, I think.&lt;/p&gt;</description>
