Fedora - Low disk space on root.

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

I am trying to figure it out now.

cd /
du -hs

Then go from there.

stacksofplates

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

I seem to remember the /root/.esmtp_queue filling up on a system one time. But that was the only thing that randomly filled up that I recall.

IRJ

dnf autoremove

Freed up about 2GB. Deleting unused kernels freed up about a 1GB. I am still searching for the real disk space hog.

scottalanmiller

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

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.

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.

IRJ

@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.
