Problem with MD5 and Root

[OmaniMan]

Hello dear ..
How are you all ??

I just wanted to upgrade Kernel to the latest version but I got problem :
***********************

cp: writing `/lib/modules/2.6.17.13/kernel/net/sched/cls_fw.ko': No space left on device
make[1]: *** [net/sched/cls_fw.ko] Error 1
make: *** [_modinst_] Error 2

***********************

I searched the largest file in /root/ but I couldn't find it dear ..

I pressed " Server Information " in WHM and it shows :

Filesystem Size Used Avail Use% Mounted on
/dev/sda1 2.0G 2.0G 0 100% /

Can you help me please to delete large files in the root folder ...

Because I want to complete upgradation of Kernel ...

Other problem is :
Today I upgraded CentOs to 4.4 and it upgraded successfully ..

I run rkhunter to check and I found one warning :
*****************************

Determining OS... Unknown
Warning: This operating system is not fully supported!
Warning: Cannot find md5_not_known
All MD5 checks will be skipped!

********************************

Is this danger ?

As to the last bit, that's simply because rkhunter hasn't been updated in months, it's not a problem so far as the OS is concerned, just means rkhunter is becoming less reliable.

Clearly you're going to have to go through / and tidy up some space.
