Putting this out into the world because it helped me solve my own "Mystery of Where All The Disk Space Went" and maybe it will help someone else:

Make your mountpoint directories immutable to prevent processes from writing to it if the drive/network/whatever device is ever disconnected:

chattr +i /mnt/mountpoint

(With the device unmounted)

If you don't do this, when your NAS disconnects and the filesystem unmounts, your web app may write to the /mnt/mountpoint directory on your root drive and then fill up all the remaining space.

Ask me how I know this. 🙃
