Woke up this morning to find out MongoDB grew to all available disk space for some reason. I cannot repair the db to compact it, as I have no space left. I can't even start postgres to remove an old database which would free up a few gigs more. I literally have zero free disk space.
I did delete a 9GB file but the space is not showing up at all when I "df -h".
I have to clear up space on the drive asap as its a production server and we're down. What to do?
