LVM block allocation for snapshots

I've found this in 'man 8 lvcreate', which raises some questions for me. So:

-s, --snapshot OriginalLogicalVolume{Name|Path}

... Thin snapshot shares same blocks within the thin pool volume. ;

Question: same blocks? Same blocks as the Origin of the Snapshot, or just "also blocks form the same pool", or ...


Side question, as I'm new to LVM: How could I find out, which blocks belong to which file on a LVM system?

You need to construct a DS that supports alloc
