confused about df -H output on system: /dev/da0s1a keeps growing...

I am seeing that my device /dev/da0s1a mounted on root keeps growing, is there a danger to this? if I go to
cd /dev/da0s1a and do 'du'
I get an output of '0'.....
I dont know why this slice keeps growing, how can I find out what is adding to the slice and what happens if it gets to 100% full...???

A quick and dirty look at what is doing what is with lsof, if you have portage installed it should be available to install

cd /usr/ports/sysutils/lsof
make install

once that is completed do

/usr/local/bin/lsof

It will then list all your processes and what files they are accessing. I'm checking to see if you can narrow it down to a particular device

Do you add files to /home and /root? It counts.

yes .. home is where I have 'users' which is only email...and in /root I have a bunch of files example...

Home should be a symbolic link to /usr/home

The /  dir should look something like this:


drwxr-xr-x  bin
drwxr-xr-x  boot
drwxr-xr-x  cdrom
lrwxr-xr-x  compat -> usr/compat
dr-xr-xr-x  dev
drwxr-xr-x  dist
drwxr-xr-x  etc
lrwxr-xr-x  home -> usr/home
drwxr-xr-x  lib
drwxr-xr-x  libexec
drwxr-xr-x  media
drwxr-xr-x  mnt
dr-xr-xr-x  proc
drwxr-xr-x  rescue
drwxr-xr-x  root
drwxr-xr-x  sbin
lrwxrwxrwx  sys -> usr/src/sys
drwxrwxrwt  tmp
drwxr-xr-x  usr
drwxr-xr-x  var

The following should be the only directories actually on the / partition


drwxr-xr-x  bin
drwxr-xr-x  boot
drwxr-xr-x  cdrom
drwxr-xr-x  dist
drwxr-xr-x  etc
drwxr-xr-x  lib
drwxr-xr-x  libexec
drwxr-xr-x  media
drwxr-xr-x  mnt
dr-xr-xr-x  proc
drwxr-xr-x  rescue
drwxr-xr-x  root
drwxr-xr-x  sbin

So the following series of commands would show what is open in each directory

lsof  bin
lsof  boot
lsof  cdrom
lsof  dist
lsof  etc
lsof  lib
lsof  libexec
lsof  media
lsof  mnt
lsof  proc
lsof  rescue
lsof  root
lsof  sbin

Do them individually and see what the outcome is.
