It seems that availability of retries depends on method. Find supports retries, findOne doesn’t. For me, it qis quite confusing behaviour because method’s names don’t tell anything about it and documentation as well. I also use writes and it seems that driver doesn’t support retryabe writes for gridfs. So I think I will catch such exceptions and retry by myself in my code.
