Drive Warning: /dev/sda3 (/usr) is 86% full - please help

I have just started new server and after less than a month i got this error message:
Drive Warning: /dev/sda3 (/usr) is 86% full

So I checked and i can see that Cpanel is using 3Gb! is that normal?
What else can I delete?
The partition has 7.8Gb, and is using 6.4 at the moment and it is rising...

Code:

root@server2 [/usr/local]# cd ..
root@server2 [/usr]# du -h --max-depth=1
27M     ./include
116K    ./man

I've checked
/usr/local/cpanel/3rdparty/mailman

and this is the usage of the directory

HTML:

root@server2 [/usr/local/cpanel/3rdparty/mailman]# du -h --max-depth=1
784K    ./tests
180K    ./cgi-bin
4.0K    ./locks

4.0K    ./suspended.lists
6.5M    ./templates
24K     ./mail
24M     ./messages
39M     .

I don't think that there is the problem...

however, when I check cpanel directory

HTML:

root@server2 [/usr/local/cpanel]# du -h --max-depth=1
16K     ./sqloptimizer

so I followed this and got to "fantastico" folder which uses up 1.9Gb. I have recently installed it, so it makes sense...in it I found a lot of .tgz's for many applications. I presume I cannot delete those .tgz's if I want users to use those applications.

If I want to move fantastico to /home directory can I do it, and how do I create symlink for it? I have not done symlink before so I would appreciate the help.

 

Well I think I have solved. I searched a little and seem to have figured symlink, it's not difficult at all for usage like this.

I have moved fantastico folder to /home and created symlink:
ln -s /home/fantastico /usr/local/cpanel/whostmgr/docroot/cgi/fantastico

Then I went into WHM and Cpanel of a user to see if Fantastico works in all of them and so far so good...

I appreciate all the help! Thank you!

 

I have automatically rejected the possibility of logs since it's new server and i doubt that it could have accumulated more than few gigas of logs...

but it will be a good reminder for someone else (me?)

 

Code:

Filesystem            Size  Used Avail Use% Mounted on
/dev/sda5             7.8G  426M  7.0G   6% /
/dev/sda8             198G   58G  130G  31% /home
/dev/sda6             996M  713M  232M  76% /tmp
/dev/sda3             7.8G  6.7G  723M  91% /usr
/dev/sda2             9.7G  4.4G  4.9G  48% /var
/dev/sda1             122M   16M  100M  14% /boot
tmpfs                1014M     0 1014M   0% /dev/shm

Thank you for your reply.
I am still having problems with this.
I have noticed that Apache logs are taking a lot of space.

Code:

root@server2 [/usr/local/apache]# du -h --max-depth=1
12K     ./cgi-bin
1.7M    ./include
52K     ./htdocs
208K    ./error
96K     ./man
944K    ./icons
288K    ./build
520M    ./domlogs
2.0G    ./logs
13M     ./manual
24M     ./modules
892K    ./lib
2.7M    ./conf
404K    ./conf_pre_ea3
1.5M    ./bin
2.6G    .
root@server2 [/usr/local/apache]#

... hmmm ... while replying my partition usage decreased.

now it's like

Code:

Filesystem            Size  Used Avail Use% Mounted on
/dev/sda5             7.8G  426M  7.0G   6% /
/dev/sda8             198G   58G  130G  31% /home
/dev/sda6             996M  713M  232M  76% /tmp
/dev/sda3             7.8G  5.3G  2.1G  72% /usr
/dev/sda2             9.7G  4.4G  4.9G  48% /var
/dev/sda1             122M   16M  100M  14% /boot
tmpfs                1014M     0 1014M   0% /dev/shm

Moment ago I have activated log rotation for Apache logs, could that have anything to do with it?

 

This server is at The Planet. How can it be that they have done this poor partitioning scheme?
