Why does the VDS show that the disk has run out. space?

Question

Network administration

I use VDS as file storage for website images. Faced a problem. On a VDS disk at 512Gb. 19Gb used. When copying pictures to this VDS, it gives an error that the disk has ended. space.
Run the command: df -h:

/dev/root        20G   19G   64K 100% /
devtmpfs        988M  4.0K  988M   1% /dev

/dev/sda2       439G   71M  417G   1% /home

The site is located along the path: /var/www/html/site.ru
As I understand it, it is now in this section: /dev/root
And how can I transfer it to this one: /dev/sda2
?

Answer 1

/dev/sda2 is mounted here /home
Therefore, you need to move the site to /home/somewhere

Answer 2

You are confusing 512 megabytes of RAM and a 20 gigabyte hard drive, and it is completely full.
