Warning: The disk usage for one or more of your partitions is running low

Hi,

I have 4TB of disc space, but the disc is full. This is impossible.

Filesystem Size Used Avail Use% Mounted on
devtmpfs 63G 0 63G 0% /dev
tmpfs 63G 668K 63G 1% /dev/shm
tmpfs 63G 9.8M 63G 1% /run
tmpfs 63G 0 63G 0% /sys/fs/cgroup
/dev/md1 3.5T 3.2T 132G 97% /
/dev/md0 2.0G 146M 1.7G 8% /boot
/dev/md2 100M 12M 89M 12% /boot/efi
tmpfs 13G 0 13G 0% /run/user/0

/dev/md1 uses too much space. How can I solve this? Can you help me?

Well... delete something to make it less full, maybe you create backups or something and they stay(?)
Besides that; this forum is made for people that maintain servers and use DA and we cant look into your server.

Try this:

How to Find Top Directories and Files (Disk Space) in Linux

This brief tutorial describes how to find the largest files, directories, and subdirectories disk usage in the Linux file system using the du and find command.

This is impossible.

Nothing is impossible.
You indeed have to look what is eating up your space.

Try like this first to see if exactly which directory is using most, if it's /home or something else.
du -h --max-depth=1 /

You can change as needed, to for example /home or change the max-depth.
More examples are in the link from @ericosman.

backup is 3.0T but backup folder is empty.. the bin trash empty. Is there somewhere else the backups are stored?

 

[ericosman]

what does it show when you ls in the backup folder?
Because it cant be empty if there is 3tb of usage...

Cant see anything (?) try it with su (sudo)

63GB+65GB
2 backup file

 

[ericosman]

See in a terminal, this is just your files.

You're looking in the wrong folder.

You're looking in /my files/backups while the 3 TB are present in /backup (not backupS) in the root of the system.

Try like this in SSH:

cd /
cd backup
ls -al

and then you will see what's taking up the space.

"/backup"

Contain system backup files, I thinks you need to delete all files inside that folder and turnoff cronjob of system backup. Admin backup should be fine enought.

Mostly, system backup should use for backup important files like customize thing.

Try using ncdu, it is a nice interactive tool.

sudo apt install ncdu

ncdu /

Explore all the files and this will give you a clue of larger files.
