Haven't got much experience with the complete send/receive to a remote
ZFS fs. However, I've created my own scripts for just sending to files.
Also, I've moved an MDT from ashift=12 to ashift=9 with send/recv. It
worked without any problems.
ZFS above 0.7.9 have issues together with dnodesize != legacy for receives:
I'll look into ZnapZend :-)
