                <link>https://jira.mongodb.org/browse/SERVER-31425</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;The &lt;a href=&quot;https://github.com/mongodb/mongo/blob/e02285559b5f15be6afbf876f169874bd9008b0b/src/mongo/db/s/config/configsvr_shard_collection_command.cpp#L901-L904&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;last step&lt;/a&gt; in _configsvrShardCollection is to migrate initial chunks from empty collections to spread them across the shards, which is only done if the collection is empty and the shard key is hashed. If there is a retryable error (like a stepdown) after the &lt;a href=&quot;https://github.com/mongodb/mongo/blob/e02285559b5f15be6afbf876f169874bd9008b0b/src/mongo/db/s/config/configsvr_shard_collection_command.cpp#L876-L884&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;step before&lt;/a&gt;, which is to actually shard the collection through the ShardingCatalogManager, then when the command is retried, it will &lt;a href=&quot;https://github.com/mongodb/mongo/blob/e02285559b5f15be6afbf876f169874bd9008b0b/src/mongo/db/s/config/configsvr_shard_collection_command.cpp#L835-L841&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;early exit successfully&lt;/a&gt; because the collection is already sharded with the same options, which skips the moveChunk call. &lt;/p&gt;</description>

There are test failures still occurring on the 4.0 branch that appear to show the same symptoms as the test failures that should have been addressed by &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-14394&quot; title=&quot;Create initial chunks directly on shards&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-14394&quot;&gt;&lt;del&gt;SERVER-14394&lt;/del&gt;&lt;/a&gt;. I see there have been backports of commits on that ticket to 4.0, so I think some further investigation needs to be done on the failures.&lt;/p&gt;</comment>
