            <title>[SERVER-44778] Two-phase index builds aborted due to rollback should leave the index unfinished in the catalog</title>
                <link>https://jira.mongodb.org/browse/SERVER-44778</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;During rollback, we abort any active index builds. The build cleans itself up and removes the durable catalog entry by calling &lt;a href=&quot;https://github.com/mongodb/mongo/blob/95c3c98350352fb4fe069a33efa478f3eb88eefc/src/mongo/db/index_builds_coordinator.cpp#L1258&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;tearDownIndexBuild() here&lt;/a&gt;. Because we are not primary, we &lt;a href=&quot;https://github.com/mongodb/mongo/blob/63fd04ad7dcfdd982a2c726d5f21a73786807a49/src/mongo/db/catalog/multi_index_block.cpp#L143&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;assign ghost timestamps&lt;/a&gt; when cleaning up unfinished indexes.&lt;/p&gt;

&lt;p&gt;This is mostly okay, because rollback will always roll-back that write. However it could be possible to take a stable checkpoint between tearing down the build and actually rolling-back. If the server crashed at this point, on startup, the index build won&apos;t get rebuilt at all.&lt;/p&gt;

&lt;p&gt;It would be more correct to just leave the index build unfinished to avoid ghost timestamping the index build cleanup.&lt;/p&gt;</description>
