Fedora - Low disk space on root.

[Obsolesce]

That's weird. I'm on Fedora 28 Workstation and upgraded it several times and my / is only using 20 GB. I have tons of crap installed.

Check the following:
/var/log
/var/cache

I've seen logs go crazy in the past, could also be the cache.

I am trying to figure it out now.

cd /
du -hs

Then go from there.

It seems like you may be on to something....

[IRJ]

/var/log is 954MB. That seems high, but not the culprit.

[IRJ]

/var/cache is 1.2GB. Again that also seems high, but likely not culprit.

[IRJ]

/var/lib is 34G. I have found my culprit.

@stacksofplates said in Fedora - Low disk space on root.:

Do du -xsh /*. Should show the highest using directories.

I am unable to use this command on /var/lib

This is the output:

[user@PCName lib]# du -xsh 
34G	.

The /var directory is the culprit, and @Obsolesce is on the right track here I think. If you haven't cd /var and run another du -hs, time to do that. du is the command I use to track down drive space issues.

Being that the system has been upgraded, my money would be on a log file growing to ginourmous proportions.

[Obsolesce]

So what software in /var/lib is taking up all the space?
du -xsh /var/lib*
ls -lash /var/lib

-s is summary. So you need to do du -xsh * to show each directory inside of there.

Fedora typically does not fill up and need cleaned out like Windows does. Chances are this is something rather unique.

In the end, it's always windows

I always fix my KVM to use /home/virtualmachines for the VMs.

I decided to delete it. I am able to RDP into Windows if I need it anyway. My total disk size is only 128GB. So I dont really have room for a 30GB VM anyway.
