+.. important:: Use a ``MAJORITY`` Write Concern
+
+   When storing files in a GridFS bucket, ensure that you use the ``WriteConcern.MAJORITY``
+   write concern. If you specify a different write concern, replica set elections that occur
+   during a GridFS file upload might interrupt the upload process and cause some file chunks
+   to be lost.
+   
+   For more information about write concerns, see the :manual:`Write Concern </reference/write-concern/>`
+   page in the Server manual.
