            <title>[SERVER-66074] Remove usage of toArray in collection_defragmentation.js</title>
                <link>https://jira.mongodb.org/browse/SERVER-66074</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;The mergeChunks state of collection_defragmentation.js &lt;a href=&quot;https://github.com/10gen/mongo/blob/0c40fc644df33161b34faa3708545e894757327e/jstests/concurrency/fsm_workloads/collection_defragmentation.js#L101-L104&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;gets all chunks&lt;/a&gt; from config.collections using toArray. If there are a lot of chunks (usually &amp;gt;100 needed) this can require a call to getMore which will fail if the test is being run on a suite that involves stepdowns (concurrency_sharded_with_stepdowns_and_balancer, concurrency_sharded_kill_primary_with_balancer, etc.).&lt;/p&gt;

&lt;p&gt;In order to allow the test to continue running on these suites, we should remove the call to toArray and simply check a random subset of the chunks for mergeability in each mergeChunks phase so that getMore is not called.&lt;/p&gt;</description>
