Isso é quase um pouco embaraçoso para perguntar, mas eu simplesmente não consigo entender isso sozinho. Estou tentando descobrir onde os discos da minha máquina são usados e se eles realmente são usados.
Se eu verificar meus discos disponíveis no meu debian, posso encontrar 4 deles. Isso parece correto. Deve haver um de 50 GB, um de 120 GB e dois de 1,5 TB. Aqui por uuid e por caminho.

Mas quando eu verifico minha montagem, não consigo encontrar todos esses discos.

Se eu verificar o uso do disco, não consigo identificar nenhum dos grandes discos de 1,5 TB

Mas na verdade eu já estou perdido aqui, acho que estou procurando a coisa errada. Alguém pode me apontar o que eu tenho que procurar se eu simplesmente quiser saber como e onde meus discos rígidos são usados no sistema operacional Debian? É que se os dois 1,5 TB não forem usados, eu posso tirá-los e usá-los para outra coisa ...
Muito obrigado antecipadamente por ajudar.

Tudo bem, agora estou totalmente confuso ... há dois grupos de volumes chamados "temp_vslide", mas eles não estão montados em lugar algum?
edite na minha busca contínua pelo uso dessas duas unidades

Você também pode tentar:
sudo pvscan
Isso mostrará se algum dos discos está em uso pelo gerenciador de volume lógico. Você também pode usar o fdisk para determinar qual dispositivo corresponde a cada unidade física:
sudo fdisk -l /dev/sda
sudo fdisk -l /dev/sdb
sudo fdisk -l /dev/sbc
sudo fdisk -l /dev/sdd
lsblk mostrará o ponto de montagem dos seus discos.
