Hi everyone;

I have a problem that is probably simple, but have not yet found the answer on any forums or by Googling. First my system specs:

Tyan 2610 motherboard w/ 2 x PIII 933
4 gig PC133 SDRAM
1 x 5 gig hd (system)
4 x 500 gig hds w/ 3Ware 7500 controller set to RAID 5, (1.5 TB) mounted as /home
CentOS 5.3 running my smb and nfs mounts

My problem is that I have run out of space on my / (root) file system, (the 5 gig). Since I am planing to rebuild my file server with larger hard drives, (2 x's 60 gig SATA's set to RAID 1, 6 x's 1.5 TB at RAID 5), within the next 2 months, I would like to try to clean out any unneeded crap rather than adding a hard drive and expanding my root file system. I have done the following:

Removed old unused kernels
cleaned up /var/log/
cleaned up /tmp

I have tried to check my disk space usage with the following commands: (output included)

[root@hydra]$ df -h
\Filesystem Size Used Avail Use% Mounted on
/dev/mapper/VolGroup00-LogVol00
3.9G 3.2G 490M 87% /
/dev/sda1 99M 13M 82M 14% /boot
tmpfs 1.5G 0 1.5G 0% /dev/shm
/dev/sdb1 1.4T 1.1T 340G 76% /home

[root@hydra]$ du -ks /var/* | sort -nr | head

60136 /var/lib

18380 /var/spool
9640 /var/www
224 /var/run

36 /var/lock
32 /var/empty

[root@hydra /]$ du --max-depth=1 -x -h /
8.0K /selinux
0 /misc
8.0K /mnt
78M /lib
0 /net
0 /proc
128M /etc
8.0K /media
132M /opt
5.3M /root
194M /var
2.7G /usr
84K /tmp
29M /sbin
8.0K /srv
4.0K /home
0 /sys
7.2M /bin
2.0K /boot
16K /lost+found
0 /dev
3.2G /

Going into my /usr and running du --max-depth=1 -x -h / gives me this:

[root@hydra usr]$ du --max-depth=1 -x -h /
8.0K /selinux
0 /misc
8.0K /mnt
78M /lib
0 /net
0 /proc
128M /etc
8.0K /media
132M /opt
5.3M /root
194M /var
2.7G /usr
84K /tmp
29M /sbin
8.0K /srv
4.0K /home
0 /sys
7.2M /bin
2.0K /boot
16K /lost+found
0 /dev
3.2G /


I have gone through /var/cache and and /var/log and deleted anything that I felt would not break my OS by deleting, I did not touch /usr yet, (I want to do more research before tampering there!!), but I am still getting this error:

[root@hydra VM Ware]$ rpm -ivh VMware-server-2.0.2-203138.i386.rpm
Preparing... ########################################### [100%]
installing package VMware-server-2.0.2-203138.i386 needs 233MB on the / filesystem

Does anyone have any suggestions on how I can clean up about 300 MB more of disk space?

Thanks

Hello zog,

since most of your disk space seems to be occupied by the /usr directory, you might find some software packages that you do not really need anymore. Try to use your package manager to find out the really big software packages installed on your root or use "du" on your /usr directory with the parameters you have used before.

Hi funnyG,

I don't have a GUI installed on my machine. I managed to delete some unused kernel sources under /user/src/kernel that gave me an extra 100 MG. If you have any other suggestions, I would be happy to listen.

Thanks

Well ... I'd be looking at
rpm -qa
and decide whether there's stuff installed you don't need/want.

I find it hard to believe that a headless machine needs 2.7GB
in /usr ...
