Today, I looked at my disc free space, after deleting some files.
I found that, after deleting approx. 28M of files, that df reported
the disc as being 93% full. Well, the last time I tried looking,
it was 85% full, just a couple of days ago. I have created a couple
of text files, and read some e-mail. But why was my disc 8% more
full than before?
I searched and searched for where the space was hiding, and could
not find it. I was comparing with the output from the earlier
du -s /some/path/* | sort -gr | head, and couldn't find it.
I did some sync commands, and tried again, and it just looked
like things should be smaller.
Eventually, I rebooted. Now du thinks that my disc is 84% full.
I don't automatically delete /tmp, and it only has 136M in it,
anyway.

At 93%, it must have been about 7098935 blocks used. How did a
reboot free up 1017187 blocks?

since basically everything is in /dev/hda5 I would venture to guess that
you have a lot of space tied up in /var that you aren't considering
how/when things go there.
du -sh /var/log
du -sh /var/cache/yum
Don't know what you are doing with this system and you may be able to
make space by doing things like 'yum clean all' or removing the log
rotations #'d .1 .2 .3 .4 in /var/log which can grow really large if you
are logging firewall stuff on a cable modem connection. Also, if you
crank up the log level on some stuff (ldap or samba come immediately to
mind - like samba log level 10) can really log a ton of stuff in very
little time.
Umm, I had done du before, and all directories showed to be the same
size as before. I used
$ ls /
bin dev home lib misc opt root selinux tftpboot usr
boot etc initrd lost+found mnt proc sbin sys tmp var
du -s /bin /boot /etc /home /lib /misc /opt /root /sbin /selinux /sys \
/tmp /usr /var | sort -gr >> du.out
Sizes two days ago:
3629612 /usr
1543788 /home
456448 /lib
383804 /var
256283 /proc
61600 /etc
48528 /tmp
20488 /boot
11884 /sbin
5040 /bin
(don't have less than this saved)

You have found the bank of Larn.
I can explain it for you, but I can't understand it for you.
I speak only for myself, and I am unanimous in that!
