8 My preference is to get rid of this whole artifical
9 disk/block-device/partition/pv/vg/lv nonsense and have one layer that
10 does it all. I really don't see the point in persisting with keeping
11 knowledge of distinct disks all the way through the stack, all of that
12 should just be abstracted into "storage" that can have rules attached
13 where you specify how you want stuff to behave (like mirroring and
14 striping).
15
16 As it is, each layer is a very thin wrapper around a physical object
17 and we only lose that distinction when we create lvs. Even though I
18 understand how the whole stack works, it's still hard to visualize (5
19 layers!) and consumes way too much time explaining it to people. All
20 rather unnecessary.
21
22 I had high hopes that ZFS would take us to a new place where all that
23 would be possible.
