Filesystem full (/ad0s1a)

S

Hi, when I look at my filesystems (df -h), /dev/ad0s1a (mounted on /) shows 104% capacity (-19% Avail).

This is FreeBSD 7.0. The box has been up and running for the past 163 days. Should I reboot it?

Thanks.
 
It is very unlikely reboot will fix that actually. Do NOT edit any system config files on / now - you would get them zero-downed.

Try to do a

# find / -xdev -type f -size +10000 -exec ls -la {} \;

to find somewhat bigger files and search for modified files in 24hrs too :

# find / -xdev -type f -mtime -1 -exec ls -la {} \;

It would help to see the output from # df -m - to see how big your / really is and to check the disk layout.

Did you do something recently that would cause rapid FS utilization (make installkernel), etc. ?

Hi matoatlantis, I didn't reboot my box.
Here is the output:

Looks like VNC and Firefox are taking up a lot of space, isnt't it?

Thanks.

Hi, I found out the vncserver log file was taking 15.2 GB! It has been removed and it all look good now.

Thanks.
 
Ouch - I see you like running X apps under root - that's not a good idea.
You should start X session under regular user and use either su in console or kdesu in KDE.

It seems that you have some core files there too. Check them with file(1) like this:
# file /etc/X11/Xorg.core

Do the same for the files below too. You can safely remove them if file identifies them as a core file (I'm guessing you are not going to do any debugging). Pay attention though, it is not necessarily core file even if it is called core.

Code: 
-rw------- 1 root wheel 15691776 Nov 30 2008 /etc/X11/Xorg.core
-rw------- 1 root wheel 16465920 Nov 19 2009 /root/opera.core
-rw------- 1 root wheel 21073920 Nov 30 2008 /root/mysql-query-browser.core
-rw------- 1 root wheel 20467712 Nov 30 2008 /root/mysql-administrator.core

Look at these directories:

Code: 
/root/.kde
/root/.vnc
/root/.mozilla

These are directories for KDE settings, VNC and firefox cache. They can grow very fast (specially firefox) - depending on your settings.

As mentioned earlier - you should not run these applications under root (there is really no need to).

Thanks for the comments. As for the root account used with X apps, I know it's not a good idea. But this box is my own personal use only, running in my basement on an old Celeron 566 24/7, on which I store my pictures, movies, music, MySQL and Apache stuff.

Now, how do I flag this thread as [RESOLVED] ?
 
Well, it's your choice really, but you know how hard it is to break bad habits, right ? ;)
