Parece que você particionou esse dispositivo de bloco. Nesse caso, você precisa montar /dev/xvdf1 , não apenas /dev/xvdf .
Eu tentei montar um armazenamento de EBS (que possui dados) em uma instância, mas ele continua gerando esse erro.
mount: wrong fs type, bad option, bad superblock on /dev/xvdf,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so.
Os detalhes do armazenamento são:
