No free space on /home after reboot

Hello,

I have a weird problem with /home partition. Thunar says: 0 bytes of 407,0 GiB free (100% used).
I have over 22gb on / partition. First of all I realize that I have a problem when opened FIrefox and don’t have any bookmarks and history (The bookmarks and history system will not be functional because one of Firefox’s files is in use by another application). Then after restart whisker menu on xfce have different icon and look.

df -h

So … uh … whats in there? Are you saying you believe the report of full to be incorrect?

du -Sh /home | sort -rh | head -20

That is not weird… free up your space on your personal folder and it will work again.

Just putting this here.

I have over 30gb before this. After deleting some files still can not copy a simple text files on my desktop.
Conky shows this:

Did you empty the Trash bin?

While it probably didnt hurt anything here …
Please do not randomly add sudo to commands.
Be especially careful about sudo anywhere near your HOME.

Now … from what we see there, and thats just 20 listings, it looks like you have simply filled all of your space. clean up.

If you have removed files, but have not recovered the space … this could be due to TRIM.
If it is a TRIM-enabled SSD you could run something like

sudo fstrim -v / 

To manually initiate trim.
(there will be no output while it works … just wait)

Yes. my trash is empty

Tip: When pasting terminal output on Discourse forums, one can either…

  • Use the Preformatted text </> toolbar button–NOT the Quote " button.

  • Add three backticks ` above and below the text (Markdown):

    ```
    type or paste code here
    ```

  • Use HTML:

    <pre><code>
    type or paste code here
    </pre></code>

Please edit your first post accordingly.

sudo fstrim -v /

This give me some space after deleting more files.

/dev/nvme0n1p3 407G 376G 11G 98% /home

And thunar - 10,4 GiB of 407,0 GiB free (97% used)

From where comes the difference

your $HOME partition is 98% full
maybe you stored files there that are not your’s (have root permissions …)?

then there is the fact that the ext4 filesystem reserves 5% of the available space by default for the root user (yes, even on your $HOME partition)
This can be adjusted with:
tune2fs -m percentage /dev/sdXy
… ~5% reserved for root on a $HOME partition of 414 GB is ~20GB only accessible to root - and lost for the users …

but even that gets full eventually - and then not even root has room to work …
