System disk almost full error

Ask Fedora
1

Hi everyone.

Before I explain anything I simply just want everyone to know that I have no experience enough with the terminal, so the whole operation was partly done by me and some help from the internet.

I just want to ask about why my /mnt/apps a directory to mount my disk, is not existing. I created one using sudo mkdir /mnt/apps in the terminal. To clarify what I was doing was actually to create a new partition in my disk with over 1tb so I can transfer over half of my programs from my system disk (where fedora is) over to that disk. Since that didn’t work out cause to the issue of /mnt/apps not existing, or what dolphin file manager confirms and so does nautilus (gnome file manager) as well.

I made it also auto-mount to my disk using the nano etc/fstab command I think. In the disk I can see an option under the 4th partition I made that it says unmount. And I think that worked actually. But I could have a theory it’s some form of bug. Cause orignially I wanted to have more space on my system disk, because my brave browser I use, it kept crashing every 20 minutes or so. And the cause of that issue was due to partly of the disk being almost at it’s fullest capacity the error said.

I have a screenshot of the error on the 4th partition

Really appreciate if someone can help with this.

Before we can really assist we need more info.
Please post the output of mount and df and lsblk -f so we can see the config and hope to assist.

When posting what is copy & pasted please use the preformmatted text tags (the </> button on the toolbar) so we see the data as formatted on your screen.

It may help us if you explain the history of your installation and current Fedora version. A fresh install of Fedora 39 normally provides adequate space for the vast majority of users, and the current default btrfs configuration avoids some of the drawbacks of fixed partition sizes.

You will find it very useful to get comfortable with the terminal and either bash or zsh (most widey used shell programs). It can help when the GUI software fails and is import when posting on this forum as text is searchable so your posts can be found with text searches by others who have experience with similar problems. Today’s internet has become dominated by low-quality clickbait sites, so I recommend Linux Command, which has been around for years.

My current version of fedora is in fact fedora 39 and I have installed it approximately a month ago.

This is far from adequate free space for a fedora system. You must make more space available to use before you can do anything else with that system. Either by enlarging the device or identifying what is filling it up and removing what is unnecessary.

Please note that I suggested the following, and you did not do that. Readability is severely hampered with the lack of suitable formatting…

Your post becomes this with formatting.

Please also post the output of sudo fdisk -l as well as sudo du -hs /* and du -hs ~/* so we can confirm the device sizes and exact partitioning as well as which paths are using the most space.

If I am reading the output of df correctly it seems that nvme01p3 should be almost 500 G and if so then it would appear that something is using an enormous amount of space for a system that was installed just a month ago.

I have now posted all the commands output in a preformatted text now. And thanks again for replying.
In the output there doesn’t seem to be programs that seem to have tremendous amount of space. But I just wanna know another thing as well. How much space should I have available on my system disk?

The one taking up space is the archive:

373G /home/anonymous/backup.tar.gz

it appears to be created by backup software, which is not ideal as you are backing up to the same disk/partition, can you provide further details?

Sorry for not responding. There is a story behind it:

So basically I wanted to backup all my files because I though they were encrypted. And then I learned about automounting and that was what I didn’t have done to my secondary disk also called backup as well as that file. I purposely made a tar file out of it to back it up. So I think that is what that file actually is.

Now I know for sure I can’t extract it to check it out, that will essentially create duplicate and that is not possible. But I am so sure that it’s a file I can remove, so that is what I am doing now.

Thanks a lot all of you.

Update:

I have permanently deleted the file.

What sometimes can happen is that the tar file itself gets included into the tar file. The tar program will then never reach the end of that file as the file keeps on growing while reading it.
