/usr is 92% full and filling up fast and I can't tell why! I'm trying to use du when in /usr but even when I use the -c parameter, it still prints out everything as it recurses through the directory. I just want a grand total. What's the quickest way to find out where all the space in my /usr is going to??? Thanks!

Also, at the end of typing

du -c

it just prints out this:

575940 .
575940 total


which doesn't look like very much even though /usr has 3344 1-M blocks!

That command will take quite a while (depending on the size of /usr), but it will print out only the size of /usr in human readable form (e.g. GB, MB, KB ... ).

Then, if you want to push in further, change the command slightly:
That will print out the size of all the immediate subdirectories in /usr in the same format as before.

Repeat as necessary.

We used to have less than 30% used on /usr but this is what I see right now:

[root@app1 usr]# df -m
Filesystem 1M-blocks Used Available Use% Mounted on
/dev/sda5 18577 16533 1101 94% /
/dev/sda3 99 16 79 17% /boot
none 2008 0 2008 0% /dev/shm
/dev/sda11 1012 33 928 4% /tmp
/dev/sda6 3344 2900 274 92% /usr
/dev/sda12 641 148 462 25% /var
/dev/sda2 2317 66 2133 3% /home


Does anything below look strange?



[root@app1 usr]# du -hs /usr/*
126M /usr/bin
4.0K /usr/dict
4.0K /usr/etc
4.0K /usr/games
22M /usr/include
154M /usr/java
4.2M /usr/kerberos
784M /usr/lib
6.3M /usr/libexec
564M /usr/local
16K /usr/lost+found
39M /usr/sbin
820M /usr/share
258M /usr/src
0 /usr/tmp
94M /usr/X11R6


[root@app1 usr]# du -hs /usr
2.9G /usr

Does anything look strange? That's not an easy question to answer. It all depends on what's installed on the system, where it's installed, where to store data files, etc.

If you're looking for a suggestion, then I'd continue looking into /usr/share and /usr/lib. Those are the biggest space consumers listed:
Keep pushing further in until you find the directory that has lots of files you don't recognize or that shouldn't be there.
