If you are able to boot normally and just want to find out what is taking up whole space, then go to the terminal (make sure you are a root user) and run the following command:

Code: Select all

du -h --max-depth=1 / 
this will show you the size of each of the directory under the root partition.

You can then follow the directory which is unusually using up more space.


If you are new to linux you can run the following commands and paste the output here so that we can help you.

1-

Code: Select all

mount
2-

Code: Select all

df -h
3-

Code: Select all

du -h --max-depth=1 /



If you are unable to boot up properly, try booting in a single user mode or use a live fedora/linux cd.

if it's a desktop with gnome installed, try using the "disk usage analyzer" under the accessories applications menu.

this will work everywhere:

Code: Select all

du -sk /* | sort -nr | more
when you find an unusually large directory, repeat that inside it:

Code: Select all

du -sk /dirname/* | sort -nr | more

Isn't it amazing how so many people can type "linuxpakistan.net" into their browsers but not "google.com"?

Hi,

When you login goto to / then run "du -sh * | grep G" this will show you size of all, next look for very odd sized folder, normally this is VAR bcz of logs (as per my past experience), then goto the odd sized folder using cd, then again perform the same task "du -sh *" by doing this you will to know the exact point bcz of which filesystem got 100%.

Or you can always use find command to find files larger then particular size.
use "man find"
Kind Regards
