Hi,

I ran into a strange problem this morning. I tried to start opera and was wondering what took it so long to start up. So I opened an xterm, issued the command "opera" from there and was amazed that according to opera my harddisc was full.

So I issued the command "df -h" which showed the following:

Code:

gentoo / # df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/sda3              56G   55G     0 100% /
udev                 1013M  276K 1013M   1% /dev
cachedir               56G   55G     0 100% /lib/splash/cache
/dev/sda4              19G  7.9G   12G  42% /xp
/dev/hda1             276G   84G  178G  32% /data
shm                  1013M     0 1013M   0% /dev/shm


So, according to df, my root partition /dev/sda3 is completely filled up with 56 gigs of data...but I'm completely clueless as to what could have filled up my harddisc..I store all my data on /dev/hda1, a 300 gig Maxtor HD which also houses the /opt filesystem.

Is there a way to find out which directories are responsible for filling up my harddisc?

Thanks alot for your quick reply!

I issued the command "du -msh /*/ , this is the output:

Code:

gentoo / # du -msh /*/
7.9M    /bin/
4.0K    /boot/
8.0K    /brenner/
84G     /data/
276K    /dev/
8.0K    /dvd/
64M     /etc/
51G     /firewire/
8.0K    /floppy/
1.1G    /home/
12M     /lib/
16K     /lost+found/
4.0K    /media/
12K     /mnt/
19G     /opt/
899M    /proc/
2.2M    /root/
9.4M    /sbin/
0       /sys/
64K     /tmp/
3.0G    /usr/
306M    /var/
7.8G    /xp/


I'm still clueless, to be honest :-( The biggest directory /data resides on the Maxtor 300 Gig HD, the directory /firewire is a mount point for my external 250 Gig Maxtor OneTouch HD. I backup all of /data to this external harddisc using rdiff-backup and cron.
/opt is symlinked to /data/opt , so those 19Gigs only affect the 300 Gig Maxtor HD.

Apart from that, there's really nothing much on the harddisc /dev/sda...but it still shows me that 56 Gigs of space have been somehow eaten up.

This line from the output of df -h irritates me, though:
Code:

cachedir               56G   55G     0 100% /lib/splash/cache


I'm using splashutils for a nice framebuffer background image..does anybody know if it's normal that this so called cachedir also shows a size of 56 gig?

TIA,

Dominik

Looking at that, you have 51 GB in /firewire.

I know you say this an external box, but are you sure you mounted it before you copied the files over?

According to df there is nothing that uses a mountpoint of /firewire.

I am of course assuming the df and the du were done at a similar time :)

Oh My Goodness, both of you were right, /dev/sdb1, which represents my external firewire disc, was indeed NOT mounted, I can't believe it!

The strange thing is, according to /etc/fstab
Code:

# This file is edited by fstab-sync - see 'man fstab-sync' for details
/dev/sda1               /boot           ext3            noauto,noatime  1 2
/dev/sda3               /               ext3            noatime         0 1
/dev/sda2               none            swap            sw              0 0
/dev/sda4               /xp             ntfs            ro,user,auto    0 0
/dev/hdc                /brenner        iso9660         noauto,ro,user  0 0
/dev/hdd                /dvd            iso9660         noauto,ro,user  0 0
/dev/fd0                /floppy         auto            noauto          0 0
/dev/hda1               /data           ext3            auto            0 0
proc                    /proc           proc            defaults        0 0
shm                     /dev/shm        tmpfs           nodev,nosuid,noexec     0 0
/dev/sdb1               /firewire       ext3            auto,rw    0 0


/dev/sdb1 should have been mounted at boot time...but it seems like it didn't...hm..well, I simply erased the contents of /firewire, mounted the external disc with mount /dev/hdb1 , now everything is back to normal again!

Thanks alot for your help, you really saved my day :-)
