[13:29:41] <zylo4747> How do I properly reset the data directory in MongoDB 4.0? Last time I deleted everything in the dbpath and i got an error because a sizeStorer.wt file was missing and I had to do a repair

[13:30:00] <zylo4747> Is there a specific set of files / directories I should delete that won't break mongodb?

[15:06:05] <Ankhers> I'm looking at https://docs.mongodb.com/manual/reference/method/db.collection.updateMany/. I just want to make sure I understand it correctly. If I call `db.collection.updateMany(filter, update, {upsert: true})', that will make ALL of those updates as upsert operations, right? Same goes for writeConcern and collation, only arrayFilters is a list that corresponds to same index in the updates list, right?

[15:11:40] <Ankhers> Or does arrayFilters also work on every element in the update list?

[15:19:18] <Ankhers> Nevermind. I think I was misreading it. I think I get it now.
