Hi Oliver,

I see and back your point since the flexibility given by LVM can be
obtained with ZFS as well.
In this case I'm not trying to achieve anything but rather dealing with
something already existing and without making too many changes I'd like to
access that volume. I think my reasoning is correct but somehow I see
something non-expected. I thought I could use pvs, and lvs later on, on any
block device as for any physical disks.

Maybe pvs is coded to work only with some devices on purpose, I haven't
looked at the source. I don't think what I'm doing is wrong in theory and I
would like to know if instead, from the theoretically point of view, it is.

Thanks, Alex
