Help~! Strange Disc Full ...running out of space...

max_tcs · 06-19-2005, 11:10 PM

i have a linux box with RH9
recently i found that my linux box running out of space

# df
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/hda2 14143744 13467836 0 100% /
/dev/hda1 99043 9321 84608 10% /boot
none 62996 0 62996 0% /dev/shm

so i remove old backup file from this server, eat space around 2G ...
But when i recheck the disk space, still same !
0% free on /
it caused mysql server unable to start ... coz there is no free space to write
what should i do now ?

Just a thought...
How did you remove the file?
(Is it still in the trash? /root/.Trash or your home .Trash).

max_tcs · 06-20-2005, 01:35 AM

nope, not in .Trash
i used the command 'rm' to remove the file directly

I got a hunch about what causes your machine to fill up but first run

Code:

du -sh `ls`

and follow your dir tree downward.

Back to my hunch look at /var/log/mysql for size, as mysql has the tendency of filling up your system with redundant data

Give me a shout if it worked.

here is the result :

Code:

# cd /
#du -sh `ls`
4.6M    bin
5.1M    boot
420K    dev
18M     etc
545M    home
4.0K    initrd
54M     lib
16K     lost+found
4.0K    misc
760M    mnt
4.0K    opt
du: `proc/4198/fd/3': No such file or directory
129M    proc
5.9M    root
12M     sbin
1.3M    tmp
4.0G    usr
4.8G    var

here i found a file named /var/log/bandwith, eat space 4G
so i deleted this file, and run again #du -sh `ls`

the result comes out :

Code:

# du -sh `ls`
4.6M    bin
5.1M    boot
420K    dev
18M     etc
545M    home
4.0K    initrd
54M     lib
16K     lost+found
4.0K    misc
760M    mnt
4.0K    opt
du: `proc/4198/fd/3': No such file or directory
129M    proc
5.9M    root
12M     sbin
1.3M    tmp
4.0G    usr
841M    var

and i check the free space again :

Code:

# df
Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/hda2             14143744  13440764         0 100% /
/dev/hda1                99043      9321     84608  10% /boot
none                     62996         0     62996   0% /dev/shm

free space still 0% .....why ?

Gibsonist · 06-20-2005, 04:40 AM

to be honest I am stumped
but i remember that the system sometimes needs a few minutes to react to changes (specially if you delete 4G)

If you use df use it with the -h flag to make the sizes human readable.

Try it again now and see if it took the changes.

max_tcs · 06-20-2005, 04:47 AM

i had reboot the machine twice already
and # updatedb
still same .....

Code:

# df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/hda2              14G   13G     0 100% /
/dev/hda1              97M  9.2M   83M  10% /boot
none                   62M     0   62M   0% /dev/shm

is that possible the HD not running properly ?

What filesystem are you using on / btw? Last time I looked RH was on ext3 and didn't support reiserfs
and what services are you running?

Marius2 · 06-20-2005, 07:46 AM

cd to /var/log and delete superfluent logfiles (and .tar.gz backups of logs). Do the same in /var/run and its subfolders. You may also want to take a look into /tmp.
