Over 250GB available BUT not enough space error

:bangbang: Tip: :bangbang:

When posting terminal output, copy the output and paste it here, wrapped in three (3) backticks, before AND after the pasted text. Like this:

```
pasted text
```

This will just cause it to be rendered like this:

Sed
sollicitudin dolor
eget nisl elit id
condimentum
arcu erat varius
cursus sem quis eros.

Instead of like this:

Sed sollicitudin dolor eget nisl elit id condimentum arcu erat varius cursus sem quis eros.

Alternatively, paste the text you wish to format as terminal output, select all pasted text, and click the </> button on the taskbar. This will indent the whole pasted section with one TAB, causing it to render the same way as described above.

Thereby increasing legibility thus making it easier for those trying to provide assistance.

For more information, please see:


:bangbang::bangbang: Also, if your language isn’t English, please prepend any and all terminal commands with LC_ALL=C. For example:

LC_ALL=C bluetoothctl

This will just cause the terminal output to be in English, making it easier to understand and debug.

Please edit your post accordingly.

There is definately something off with your file system

I don’t know what. Compare your df output with mine

 $ df --human-readable /
Filesystem      Size  Used Avail Use% Mounted on
/dev/nvme0n1p2  468G   39G  429G   9% /

Perhaps you think you have moved the data - from one folder to another - but what if the destination was not mounted as you thought - then the data is still on the original device - not on the device partition your thought you copied the data to.

It is easy to confuse yourself - as Linux does not use the term drives but mounts …

Hmm, that’s a lot.

Not intentionally, then.

Please provide the output of:

sorry, I mounted the external drive there
after umnounting it, it looks like the last one

yeah thats a theory- I can tell for sure, that the data have been moved successfully to the external drive
and when i want to check if its still on my internal drive it doesn’t appear

Familiarize yourself with :point_down:

does that mean you wanna tell me mounting an external drive in /home is responsible for my problem?
because I’ve been using this a very long time and the error just appears now…

Then, run:

sudo du --human-readable /

…and:

df --human-readable /

…again, to see if it’s better. Provide the output here, if you will.

df --human-readable /                                                                                                                                                                               ✔

OK, this looks like a LUKS encrypted system/container and I know nothing 'bout that, so I is out.

Eh?

This whole thread reminds me of what is referred as an xy problem - that is you experience a problem and you have tried to fix it but the fix didn’t work and now you ask for help on the fix that didn’t work.

I am fairly certain you issue is cause by some circular mount loop so data which is expected to be elsewhere is still on the partition - that is entirely possible.

please provide the output from

mount

and the output from

cat /etc/fstab

and the output from

lsblk -a

I saw earlier you have several snap loops mounted - that indicates you have some snaps installed which can cause your disk space to go haywire.

 sudo snap list
 sudo snap remove <pkg-name>

List all snap related services and sockets

systemctl list-unit-files | grep snap

Then stop and disable the services

systemctl disable --now <some-snap.service>

Then remove all snap related packages from the system - when that is done you look for

For reference:

huh? please tell me what I am doing wrong! Sorry, just have no idead whats happening now.

Just a thought… did you actually delete or did you move it to trash bin? Check your trash bin :wink:

To add here. Search for Trash folders:

sudo find / -type d -readable \( -wholename "*[Tt]rash/files" -or -wholename "*.[Tt]rash-1000/files" \) 2>/dev/null

And check them for “deleted” files manually.

Could you please detach your external storage and keep it detached.

Then post the output of

In any case the file system clearly states you have used 897GB out of 899GB.

I have no idea - it - kind’a - remind me why I am not fond of btrfs - I remember btrfs did that stunt on me many years back - and I really don’t like it.

My system - for the moment - runs with btrfs - but I have weird issues and freezes where my hdd activity light goes steady blinking like something is terribly wrong - it takes a long time before it settles.

You clearly state that you have moved data off the disk
You have emptied the trash - either in Nautilus or manually like described above

rm -rf ~/.local/share/Trash

Perhaps it is worth rechecking your trash

It is worth understanding how an SSD handles files within memory cells.

I am guessing now

  • I really have no idea
  • your luks encrypted volume hides the content for prying eyes so the underlying SSD only knows of one big container
  • what is inside the container is handled by another layer
  • so the SSD goes
  • in cell terms - full and somewhere in the communication between the elements
    • the ssd controller
    • the kernel
    • the luks container
    • the btrfs filesystem inside the container
      • go haywire
  • the controller says
    • I am full
  • the filesystem says
    • no you are not
  • who wins?

btrfs filesystem defragment

hmm… okay :-/
so what is your opionion? use ext4 instead?
with my external drive detached I am now running another balance and will see where that takes me… after that I’ll try de fragmentation and post my results here.

anyways: I really thank you for your time and help!!

I know what I am going to do the next 15 minutes - I am going to get rid of btrfs for - I don’t have count any more - 20th time :slight_smile:

I am going for a

buildiso -p kde -b unstable -k linux61
