Resize root directory in Fedora 29 Server.
 

Cannot do updates because of no disk space in the root directory. Deleted the history of Firefox in Root user and deleted history in Chrome and Firefox in user rickhrkachjr. Root Directory Still shows red in Disk Usage Analyzer. The other trouble I am Having is knowing which device houses what files in order to know which device to increase and which to decrease. The following is what I mean:
/dev/sda3 ext4 /Boot 1gig
/dev/sda4 Extended 926.73gig
/dev/sda5 lvm2pv 926.73gig 22.85gig used
gparted is not helping me to shrink where I think I need to shrink.

I'm using KDE desktop in Fedora 29, KDE partition manager says I have 18.80GB of 18.80GB used up in lvm2pv, but everything works. Yours is showing only 22.85GB used out of 926.73GB in lvm2pv, which means you have lots of free space.
What does df command show, below is what mine shows, only 41% used:
You may need to clean out downloaded package cache, possibly over the limit, if you don't think you'll need packages that are already installed, run command: dnf clean packages

Hers what I have
 

[root@HomeEG1 ~]# dnf clean packages
0 files removed
[root@HomeEG1 ~]# df

One question comes to mind, how do I see hidden files?

Let me try this again.

Learning something new every day.

Run this to see the worst space consumers - be patient, it will take a while. I find PackageKit to be a problem child.

This is what I got
 

That /var/cache/PackageKit sure seems rather large. I don't have that directory on my system/distribution, but my whole /var/cache is less then 1 MB
I would look into /var/cache/PackageKit to see what can be cleaned up there. The 29 directory seems to be most of it (2.2G out of the 2.4G in total) and the metadata again is most of 29.

On the other hand, your root seems to be in a LVM logical volume.
Does the vg (Volume Group) have any free allocation units left?
Read up about LVM and lv management if you don't understand this.

But IF the vg has free space, it is easy to extend the root with lvextend.
Note that afterwards the file system has to be extended too and that cannot be done while you're running from it, so you'll need a LIVE fs with LVM support to do so.

Many Linux-native filesystems can be expanded (but not shrunk) while mounted. lvextend can do this automatically if you include the "--resizefs" option. This works for any filesystem supported by the fsadm utility (ext2, ext3, ext4, ReiserFS, and XFS).

Since you're using LVM, what do the commands pvs, vgs, and lvs show?

Ah, learned something new again, thanks!

Don't close this ticket
 

This might take a little bit but I would like to post the fix.

Is this what you are looking for in those commands
 

Should I have used the format in the previous command?

I am using Gnome as a GUI
 

Does using Gnome create more packages for the GUI environment or any of the alternate sites for packages?

So, you have more than 900GB available for extending /. You can use lvextend to add space to /.

The pvs command gives a summary of your physical volumes (that is the disks/partitions used by LVM). The vgs command gives a summary of the volume groups (that's the storage pool that is made up of the physical volumes). The lvs gives a summary of the logical volumes (that's how the storage is divided up). The vgs shows that the volume group is 926.73g, and there is still nearly 903.88g available for logical volumes.

With lvextend you can give it the exact size you want the lv to be or you can add space. For example, the following command will extend / to 20G:

The '-L20G' tells it the size and '-r' tells it to resize the file system (if you don't include that, you have to resize the file system after the lvextend).

This will add 5GB:

With all of that space, you can create more logical volumes or add it all to /. Personally, I split things up to keep my data separate from the OS. That way, I can install a new OS from scratch on the OS logical volume(s) while leaving the data untouched.

You should really read up on LVM to really get an idea of the different things you can do with it. It gives you a lot of flexibility, especially with servers, but I use on everything, including laptops.
