donde esta el put… disco

En un proxmox con zfs, no encuentro el disco. Maldición. 

#   Me guio de 
#   https://forum.proxmox.com/threads/location-of-disk-images-in-local-lvm.83082/post-365673

#   la vm tiene que estar apagada, y saber el nombre del disco
#   Obtengo la ubicacion del disco
pvesm path zfs:vm-102-disk-0
#   convierto a archivo
dd if=/dev/zvol/zfs/vm-102-disk-0 of=vm-102-disk-0.raw
