Não é possível montar o LVM Ubuntu 16.04

1

Sou meio novo nessa coisa do LVM. Eu tenho um disco rígido que eu preciso montar para recuperar alguns arquivos importantes. O disco rígido era originalmente de um Xenserver Centrix.

Aqui está a saída de fdisk -l para o disco:

Disk /dev/sda: 232,9 GiB, 250059350016 bytes, 488397168 sectors

Quando tento montar, recebo isto:

$ sudo mount /dev/VG_XenStorage-e87e45db-88b6-fe01-9d35-c19431cee0f3/VHD-100b96bd-dd71-4c78-b8fd-3c9bb7ad6ae2 /media/lvm/
mount: wrong fs type, bad option, bad superblock on /dev/mapper/VG_XenStorage--e87e45db--88b6--fe01--9d35--c19431cee0f3-VHD--100b96bd--dd71--4c78--b8fd--3c9bb7ad6ae2,
       missing codepage or helper program, or other error

       In some cases useful info is found in syslog - try
       dmesg | tail or so.

Alguém pode por favor apontar o que está errado? Obrigado.
