Why is my root large?

[TheFu]

The df output is correct.
The storage used is by partition.

If you ever had a /home under / (on the same partition)and put files there before creating the /home mount point and mounting a new partition there, then all those files are still sitting under the / partition (sda3) - effectively hidden because the other partition mounted as /home (sda4) hides it. That data is "hidden", if it exists. I've seen this happen with backup partitions that weren't mounted for 1 backup job, so / got filled.

All of us have thought there was no way that files existed eating up storage over the yrs. Looking closer, I've always been able to find where the "lost space" was ... eventually. Usually, I start with the df -h command, then use the du -sh * as I move down the directory tree to find the files/directories hogging storage. Please trust us. You have files that are NOT on /home that are under sda3 on /.

I'm with steeldriver - use the CLI tools, not GUIs for this. GUIs tend to oversimplify things and might not show the truth. We care about truth here, not a pretty diagram.

[Dave_L]

The du command is handy for digging into this.

Example:

sudo du -h /var --max-depth=1

[buzzingrobot]

You have a single filesystem that uses multiple partitions. You might easily have put /boot, /etc, /tmp, /var, /usr/local, and more on their own partitions, or on their own partitions on their own drives.

The "Disk Usage Analyzer" seems to display results using the filesystem's view of things. All files and directories are part of a hierarchy beneath "/".

[SuperFreak]

This is clearer now. I opened File Sytem and found home which ontained a few files including trash and lost and found but my home directory "david" was as everyone seems to be saying a symbolic link not the actual directory.
Thank you all for providing the commands I will try them and see if there is a big resource hog in Root

The advantage (one of several) of keeping home on a separate partition is that if your root drive/partition gets trashed, you could boot a LiveUSB and mount your home partition and have all of your work and personal files preserved. The downside is that some tools (as you have noticed) will hide the relationship between disk space use and the directory tree. Add a few remote file servers to your mount table and things quickly get confusing.

Presumably this is why it does in fact appear that my home folder contents are counted towards the total capacity of the Root Directory both in GParted and Disk Usage Analyzer. Presumably this is because they are on the same disk although separate partitions. The /media/Music directory is on a separate disk and partition and is not counted towards Roots capacity
Using

sudo du -h /var --max-depth=1

command that Dave_L gave I looked at all the directories in my Root and added them up. Unless I add in the value for Home I don't get a total equal to what GParted( where as I said before root and home are separate partitions) said root is.

Please forgive my confusion. I enjoy tinkering and using computers but I really have very little technical experience

[TheFu]

gparted/parted tells the truth at the partition level. If /home is mounted to a different partition, then that storage is NOT included in the / mount storage reports.

I cannot speak to how other GUI tools work. Don't use them.
I trust df and du.

I'd have to check a little to see how LVM LVs munge this stuff. It doesn't, df still works as expected. Just checked.

BTW, /home is not some mandatory name or location. It can be named anything you like, just the passwd entry data would need to be modified to know where it is for each userid. Different users can have their HOME on the same or different partitions as well. At prior work places, our HOME directories were NFS mounted to every UNIX machine we had logins on. Same HOME regardless of the platform is handy, though it can mess with startup and config scripts - especially when the tools are in different locations for different machine architectures.

gparted/parted tells the truth at the partition level. If /home is mounted to a different partition, then that storage is NOT included in the / mount storage reports.

That being the case I have to wonder about whether I have home within the root partition as well as as it's own partition, because otherwise the numbers don't seem to add up.
If I add up all the directories below (file system which I believe is Root or /)I get approximately 15 GB with Home included but media excluded(as it clearly is not counted part of root in Gparted). This is a bit shy of the 16.7 GParted says is used in Root partition but much closer than if I didn't count Home(6.5GB) in Root. Is the home directory duplicated then in Root and in it's own partition?

That being the case I have to wonder about whether I have home within the root partition as well as as it's own partition, because otherwise the numbers don't seem to add up.
If I add up all the directories below (file system which I believe is Root or /)I get approximately 15 GB with Home included but media excluded(as it clearly is not counted part of root in Gparted). This is a bit shy of the 16.7 GParted says is used in Root partition but much closer than if I didn't count Home(6.5GB) in Root. Is the home directory duplicated then in Root and in it's own partition?

Can't have partitions inside of partitions. If you created /home as a separate partition, it is.

Some tools use 1024k as a kilobyte. Others round down to 1000k. That might account for the slight difference. (Actually, all those numbers have been rounded to a single decimal place. I.e., 1,024,001 bytes and 995,001 bytes both get rounded to 1.0M, obscuring the difference of 29000 bytes.)

It makes sense what you are saying but if I don't include the home volume in the total for Root then Root works out to less than 9 GB which is considerably less than the 16.7 GB GParted reports Root as. That is not really a slight difference. And yes I did create separate partitions for / and home using Something Different option in the installation.

We seem to be rehashing the same points. My issue is I don't understand why my Root partition as reported by Gparted is so big since home is a separate partition (see first image post 1) and I have added up the volumes using both graphical and CLI and the only explanation I can come up with is either home is duplicated in root (which you say is not possible) or Gparted is not reporting correctly or the more obvious explanation I have misunderstood the matter
