I get this error : "cp: error writing '/boot/umlinuz-5.15.26-gentoo-x86_64' : no space left on device".

the strange problem is that my hardrive space is 1tb. the file system is formatted to ext4. i did everything the handbook said and i always get this error after trying to install the kernel (even manually).

What does df -h /boot show? Your /boot partition is probably too small.

Yep, you've only got a total of 2.8M of space on /boot. You need a larger partition than that. The handbook recommends 256M. You can either reinstall, or shrink your / partition and expand /boot (this depends on your disk layout though).
