Answer 1

Seu comando está tentando montar o dispositivo, em vez da partição.

Em vez de mount -t ext2 /dev/xvdb /mnt , tente usar:

mount -t ext4 /dev/xvdb2 /mnt

Se você gostaria de montar automaticamente esta partição na inicialização, você também precisará adicionar a partição ao seu arquivo fstab.

Você precisa conhecer o UUID do seu disco, que você pode encontrar com ls -l /dev/disk/by-uuid/ , e depois procurar sua unidade de 2 TB. Este parece ser o 5a99aec9-7270-44ce-9df7-32ff4d70a75b para o seu disco.

Em seguida, você precisará editar /etc/fstab e adicionar a seguinte linha:

UUID=5a99aec9-7270-44ce-9df7-32ff4d70a75b /mnt ext4 defaults 1 2
