Linux disk space is disappearing problem

[workisnotfun]

Hi everyone,

I am having a problem where when I leave my fedora 17 on for too long, my hard drive somehow completely fills up, leaving no room to write/save any files. This problem repeats itself when I reboot and the disk space is all freed but it is taking a terrible toll on my computer. The fan runs fast and computer temperature goes very high.

What could be the problem and how can I fix this? Each minute or so I run df -h and my available space decreases by .1G.

My thoughts is that a run away process needs to be stopped or I have a virus.

Any thoughts, comments, suggestions are greatly appreciated. Thanks.

Hi and Welcome !

Have you ever cleared cache of Package Manager? Execute this in Terminal

su -c 'yum clean all'
df -h

Post the output of fdisk -l and df -h commands here.

Here is the output of df-h
fdisk -l does not print anything out.

Normally the Use% is 2% for /home and here is the output for the command

su -c 'yum clean all'

fdisk -l does not print anything out.

That is expected behavior when the command is run as a normal user. You need to run it as root.

Here's the actual output of fdisk -l

Any thoughts on what's draining my disk space?

[workisnotfun]

I'm not sure if this is related or not but my internet connection turns on and off periodically (not randomly) when this periodic loss of memory occurs. Also I am dual booting Windows 7 where my internet connection never does this.

[yancek]

I'm not sure what is causing your problem and don't see anything unusual in your df -h or fdisk output other than that your /home partition is half the size of the / partition. Usually, people will have a /home partition which is much larger than /. Also, having 44% used should not be a problem. I think seeing 2% of a /home partition full/used would be pretty rare. Maybe DC or someone else who knows more about this will post?

[workisnotfun]

Actually I was exaggerating and normally lowest I've seen is 7% Used. If I leave my laptop on for several hours more, it goes to 99%-100% full and I can't even save anymore(text files for example).

When this happens I have to shut all programs then shut down and turn on again. Though this temporary fixes the problem, I really want a permanent solution.
