                            <comment id="763857" author="spencer" created="Thu, 13 Nov 2014 21:38:07 +0000"  >&lt;p&gt;Seems like implicit database creation is broken in 2.8 somehow.  This is masked in a pure 2.8 replica set as now we when we create a collection implicitly via an insert we log an explicit createCollection entry in the primary&apos;s oplog, so the secondary replicates that before the insert.  2.6 primaries don&apos;t do that, so the insert is the first time the secondary has seen anything about this new database/collection.&lt;/p&gt;</comment>
                            <comment id="763854" author="milkie" created="Thu, 13 Nov 2014 21:35:18 +0000"  >&lt;p&gt;If you turn off prefetching, does that stop the crash?  I would expect that the actual application of the op should implicitly create the database successfully with no crash.&lt;/p&gt;</comment>
                            <comment id="763853" author="milkie" created="Thu, 13 Nov 2014 21:34:37 +0000"  >&lt;p&gt;Why does the prefetch code crash instead of simply skipping the nonexistent op, or creating the database?  Ideally it should happen there.&lt;/p&gt;</comment>
                            <comment id="763848" author="mattd@10gen.com" created="Thu, 13 Nov 2014 21:28:29 +0000"  >&lt;p&gt;If I create the database by inserting into another collection on the database prior to upgrading the node, the crash does not occur because the database exists.&lt;/p&gt;

&lt;p&gt;2.8 creates an oplog entry for collection creation on an insert into a new collection, which will create the database.&lt;br/&gt;
2.6 does not. The collection and database creation is implicit.&lt;br/&gt;
I believe the solution is to have 2.8 notice the missing database (easy) and have it create it (not something I know how to do offhand, but probably similarly easy).&lt;/p&gt;</comment>

investigating further...&lt;/p&gt;</comment>
