My disk is full, even tho /home shouldnt even use half of it

Issues & Assistance KDE

Hey guys, so as you can see i have my /home partition seperately since i like to have it that way. Now here is the Problem, even tho the /home folder just uses 152 GiB, my partition still uses 367GIB for some reason. Now this is bad, since it doesnt allow me to install some bigger stuff from for example lutris, even tho i have the space.

Here is the output of

btrfs filesystem du /home
 152.59GiB   323.33MiB   133.01GiB  /home

and i also got this

× sudo btrfs fi show
Label: none  uuid: c62e35b2-c344-4a40-bff0-abcde7e3ec22
	Total devices 1 FS bytes used 36.55GiB
	devid    1 size 50.00GiB used 39.07GiB path /dev/nvme0n1p3

	Total devices 1 FS bytes used 365.98GiB
	devid    1 size 399.26GiB used 373.02GiB path /dev/nvme0n1p4

Can anyone help me out here?

The problem is unclear. Are you trying to determine what is on the disk, using up the 367 GB? If so, what is the obstacle preventing you from just looking at the files?

Please show the output of lsblk -f.

I also want to know why, when i deleted my Trash with like 100GiB in it my disk didnt free anything up

here you go

Also i did look at the files directly, thats why i noticed it

Is your filesystem occupying the entire partition? Try:

sudo btrfs filesystem resize max /home

1 Like
5

yes,

 λ sudo btrfs filesystem resize max /home
Resize device id 1 (/dev/nvme0n1p4) from 399.26GiB to max
6

That does look confusing. Is nvme0n1p4 holding snapshots?

yes i have a snapshot config for /home. But .snapshots is in /home and i have shown u before my whole /home folder holds in total 152 GiB, so that shouldnt be the issue i think?

Have you tried using the btrfs filesystem balance tool in Garuda Assistant?

9

yes, but i dont think it does anything. When i pressed start full balance it tells me to look for the system process and when i look at it in terminal it doesnt exist

10

Where are you seeing this? I am seeing you are using more like 328 GB in your home folder.

I don't have my computer in front of me, but isn't that output missing descriptors for the three outputs? I can't tell what those values represent.

What is the output of sudo btrfs filesystem du -s --human-readable /home?

Did you type sudo?

15

no, but when i do it, it doesnt end for some reason. But i also dont know why i would need to do that in /home

16

It looks like the snapshots are system files. I'm guessing that is where your extra space is tied up, and why your btrfs du is not expressing the full value of used space.

I would delete some of those snapshots to free up the space you need, it looks like you are a bit heavy.

hm seems like you are right, seems like snapshots of /home really clutter your shit fastly. i deleted the config for it and now it fits
thought this would be a really space light way to backup.

18

You are right, the snapshots add up fast and in my opinion the defaults are set kind of high.

I have mine set to hold one snapshot per day, and one per week and that's it. If I need restoration beyond the scope of those two snapshots I will use my actual rsync external hard drive backups.
