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