pve zfs and drbd

Just pulling the thread-end...I'm still looking for a performant way of clustering. Ceph/Gluster/... are nice, but just not fast enough. As i love ZFS, and DRBD9 supports multiple nodes, i've stumpled upon this: http://v-optimal.nl/index.php/2016/02/04/ha-zfs/
Interesting idea.
Just thinking of this:
- local disks (either native or probably ZFS RAID something)
- DRBD on top
- ZFS on top (SNAPSHOTS, BABY, SNAPSHOTS!)

The "easiest" setup would be with a multi-attachable disk shelf if you have some laying around and only want two-node ZFS for e.g. a SAN (iSCSI or FC). You then "only" need the HA and ZFS part. I have this setup still on my todo list for try out.
Technically it will be possible what you want, but it'll be very slow. There is also the general rule not to use a COW on a COW system. I read this everywhere, yet I never read an explanation (maybe someone can jump in, IMHO is just speed)

Would be interesting how these guys are doing things: http://www.zeta.systems/zetavault/high-availability/
Would even pay for it, when it's open source. But i hate vendor lock-ins.
