Migration from ZEVO to OpenZFS

Hello, everyone! Today, I finally migrated from ZEVO to OpenZFS 1.2.7, and it was totally seamless. All I did was shut down my old ZEVO system, unplug the disk array, plug it into my new Mac Pro running 10.9 (with Mavericks installed), and then run "sudo zpool import tank". Done!

Not only did it just work, but disk performance has improved dramatically. I'm (now) happily on a Mac Pro running Mavericks 10.9, talking to a 8 x 4TB Areca Thunderbolt enclosure and getting about 1.4 GB/s read and write—at least, using Black Magic's Speed Test, which I'm told might not be the best test (about 3x what I was getting on 10.8 and ZEVO).

Congratulations—and, thank you—, developers and community supporters, for making this work for those of us who are not actively contributing code!

OK, so those negative read speeds might invalidate this test... ;)

Even though F_NOCACHE is not currently honored, you can at least probably get the benchmark working by setting

Code: Select all
zfs set primarycache=none tank
zfs set secondarycache=none tank

and reloading the kexts or rebooting.

(You would want to revert these later though.)
