            <title>[SERVER-80107] Failovers can break time-series creation</title>
                <link>https://jira.mongodb.org/browse/SERVER-80107</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;In &lt;a href=&quot;https://parsley.mongodb.com/resmoke/a531d6fc5e1f5a4cceabe3f37d64fe37/all?bookmarks=0,165218,180467&amp;amp;filters=000%2522fatal,100timeseries_insert,101%255E%255C%255Bj0%253A&amp;amp;highlights=timeseries_insert&amp;amp;shareLine=165218&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;a recent test run&lt;/a&gt; against REP-2771&#8217;s development branch for time-series support, I saw this error:&lt;/p&gt;
&lt;blockquote&gt;
&lt;p&gt;(NamespaceExists) namespace test.timeseries_insert already exists, but is a view on test.system.buckets.timeseries_insert rather than test.&lt;/p&gt;&lt;/blockquote&gt;
&lt;p&gt;The verbiage seems a bit frustrated, and there &lt;em&gt;really&lt;/em&gt; shouldn&#8217;t be actual namespace conflicts at that point in a mongosync CI run since each namespace gets exactly 1 `create`, and nothing else alters the destination cluster at that time.&lt;/p&gt;

&lt;p&gt;It looks like what happened was that an election happened midway through creation of a time-series collection (via the public API, not creating buckets+view directly), and maybe that confused things afterward.&lt;/p&gt;

&lt;p&gt;One potential workaround is for mongosync to create the buckets &amp;amp; view separately; I haven&#8217;t yet investigated that change to see if it&#8217;ll work.&lt;/p&gt;</description>
