Filesystem / (root) run ouf of space

Good evening, I've got a question, in our production system there is an application called Intermediate which ftp service is the core to to send back and forth from/to diferent destinations

Gradually FS / was ruuning out space and we took a long time to figure out what precesses were eating up this FS /

our SA found a folder called /dcs/data13 taking up 5.4 GB of space located 0n FS / (root)

to checku up /dcs/data13 is not a FS but a folder mounted in FS /,

I've got a couple of questions:

1 why i cant see the path when execute the command df -h
2 why the application let me create /dcs/data13 asuming it was a path? it shoud have yield an error if filesytem /dcs/data13 didnt exist
3 is true if FS / get 100 % full is probably the server shut itself down ?

I appreciate your help in advanved, here is the scrren of FS mounted

Code:

df -h

fdformat

FDFORMAT(8)						     Linux Programmer's Manual						       FDFORMAT(8)

NAME

       fdformat - Low-level formats a floppy disk

SYNOPSIS

       fdformat [ -n ] device

DESCRIPTION

       fdformat  does  a  low  level  format on a floppy disk.	device is usually one of the following (for floppy devices, the major = 2, and the
       minor is shown for informational purposes only):

	      /dev/fd0d360  (minor = 4)
	      /dev/fd0h1200 (minor = 8)
	      /dev/fd0D360  (minor = 12)
	      /dev/fd0H360  (minor = 12)
	      /dev/fd0D720  (minor = 16)
	      /dev/fd0H720  (minor = 16)
	      /dev/fd0h360  (minor = 20)
	      /dev/fd0h720  (minor = 24)
	      /dev/fd0H1440 (minor = 28)

	      /dev/fd1d360  (minor = 5)
	      /dev/fd1h1200 (minor = 9)
	      /dev/fd1D360  (minor = 13)
	      /dev/fd1H360  (minor = 13)
	      /dev/fd1D720  (minor = 17)
	      /dev/fd1H720  (minor = 17)
	      /dev/fd1h360  (minor = 21)
	      /dev/fd1h720  (minor = 25)
	      /dev/fd1H1440 (minor = 29)

       The generic floppy devices, /dev/fd0 and /dev/fd1, will fail to work with fdformat when a non-standard format is being used, or if the for-
       mat has not been autodetected earlier.  In this case, use setfdprm(8) to load the disk parameters.

OPTIONS

       -n     No verify.  This option will disable the verification that is performed after the format.
