This isn't about whether the metadata compresses, this is about
whether ZFS is smart enough to use all the space in a 4k block for
metadata, rather than assuming it can fit at best 512 bytes,
regardless of ashift. By packing, I meant packing them full

What is going on? Is there really that much metadata overhead? How
many metadata blocks are needed for each 8k vol block, and are they

Thus I proposed the second idea with a code-only solution
to optimize performance (force user-configured minimal
data block sizes and physical alignments) where metadata
blocks would remain 512 bytes because the pool is formally
ashift=9 - and on-disk data

I sent a zvol from host a, to host b, twice. Host b has two pools,
one ashift=9, one ashift=12. I sent the zvol to each of the pools on
b. The original source pool is ashift=9, and an old revision (2009_06
because it's still running xen).
