It's also good to know the quality you can expect from a company's production releases - zfs was not ready for the real world. The io error hardening (bug id #6386910) looks like it may have been fixed in March of 2007, but Sun released this FS to the world with much hype in May of 2006. That's somewhere around 9 months for something flaunted and mercilessly promoted as a the world most advanced file system.
Maybe it's great now, maybe it's not, I can only say that based on what we've seen -- I wouldn't touch it. There are much more tried and true filesystems out there for critical data, maybe once it has the years and the track record that some of the others filesystems have (like ext and ufs) it might be comparable in stability by then...but at 9 months for a bug fix - one has to wonder when it will actually even come close.
Speaking from personal experience - This file system is far from ready. It can kernel panic and reboot after minor IO errors, we were hosed by it, and probably won't ever revisit it.
This phenomenon can be repeated with a usb device, you might want to try it before you hype it.
Try a google search on it and see what you think...there is no fsck or repair, once it's hosed, it's hosed, the recovery is to go to tape.
