Very true. I recently had someone imply to me that ZFS was a network protocol and everything else related to disks and file sharing -- instead of volume manager integrated with a filesystem and an automounter. There is hype and misinformation out there.I've seen people wondering if ZFS was a scam because the claims just seemed too good to be true. Given that ZFS *is* really great, I don't think it would hurt to prominently advertise limitations like this one it would probably benefit credibility considerably, and it's a real consideration for anyone who's doing RAID-Z.
As for the claims, I don't buy that it's impossible to corrupt a ZFS volume. I've replicated the demo where the guy dd's /dev/urandom over part of the disk, and I believe that works -- but there are a lot of other ways to corrupt a filesystem in the real world. I'm spending this morning setting up a server to try ZFS in our environment -- which will put it under a heavy load with a lot of large files and heavy churn. We'll see what happens!
