I've got a RAID-Z2 array that is being kind of weird, and I'm not entirely sure where the problem is, but it has never lost data. At first I thought it was a marginal disk. Now I'm thinking it might be the controller. It's amazing how easy it is to work with ZFS though. I was able to take each drive out of the pool, run badblocks on it (read/write to exercise it and look for errors), and then add it back in once it passed the burn in test. Easy peasy. Even with each drive being a dm-crypt. I've been using ZFS for a very long time, and never had data loss on it. Even back in the early days of ZFS+FUSE under Linux. At one time I had 5 big systems running ZFS for backups of ~150 machines.
