Perfectly clear. Thanks.

I've solved this in a more simpler way: i've discovered that a 'thin'
filesystem (in my case, ZFS) can allocate a 2TB RAW image in a 800GB
ZFS volume, obviously providing that there's no more then 800GB of data
in the volume.
So, i've simply moved the image as RAW.
Thanks!
