Gentoo Eats Disk Space

nuliknol · 06-23-2010, 11:08 AM

Hi, i have a installed Gentoo linux few years ago and i never restarted the server since that. Right now the 'du' reports 37GB used while the 'df' reports 61GB. These 2 numbers do not match. Is this because i never did fsck for years? How do find where the remaining 24 GB are ? I can't restart the server.

Here is the info:
gentoo / # du -skc
37441106 .

gentoo / # cat /proc/mounts
rootfs / rootfs rw 0 0
/dev/cciss/c0d0p1 / ext3 rw,noatime 0 0
proc /proc proc rw,nodiratime 0 0
sysfs /sys sysfs rw 0 0
udev /dev tmpfs rw,nosuid 0 0

/dev/ram0 /ram0 ext2 rw 0 0

Install filelight and run it -as root- on /. If your server does not have a screen, then use ssh -X root@host to display filelight on an other Linux computer (using a live-cd if you use windows).

If you haven't restarted your server for over four years, then I think you will be seriously behind with the security patches and updates. You should address this problem very soon.

I can't restart the server.

Do you mean you are unable to, do not know how to, or do not want to restart the server?

Do it as "du / -xck | sort -nr | head -n 20". That'll give you the top consumers to work on.
