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

mkdevmaps

mkdevmaps(1M)						  System Administration Commands					     mkdevmaps(1M)

NAME

       mkdevmaps - make device_maps entries

SYNOPSIS

       /usr/sbin/mkdevmaps

DESCRIPTION

       The  mkdevmaps  command	writes	to standard out a set of device_maps(4) entries describing the system's frame buffer, audio, and removable
       media devices.

       The mkdevmaps command is used by the init.d(4) scripts to create or update the /etc/security/device_maps file.

       Entries are generated based on the device special files found in /dev. For the different  categories  of  devices,  the	mkdevmaps  command
       checks for the following files under /dev:

       audio	       /dev/audio, /dev/audioctl, /dev/sound/...
       tape	       /dev/rst*, /dev/nrst*, /dev/rmt/...
       floppy	       /dev/diskette, /dev/fd*, /dev/rdiskette, /dev/rfd*
       removable disk  /dev/dsk/c0t?d0s?, /dev/rdsk/c0t?d0s?
       frame buffer    /dev/fb
