Please tell me how my entire FS will be toast if the wrong bits are turned, especially when zraid2 is really the only valid solution that should be used.
I've been using ZFS for years now, i've had disks go bad, I've replaced them. ZFS has protected me from data loss better than anything else. In the past when I've had the disk lie to me, ZFS was able to tell me what files were corrupted and thus had invalid data.
I'm going to need to throw a [citation needed] on your post.

- X-Istence 14y agoI have been paying attention, and in a lot of cases where there is corruption a fsck wouldn't help anyway. I've had corruption on ZFS, UFS, ext3, ext4, HFS, HFS+ and the only one where I have lost almost no data or no data at all is ZFS (the only time I've lost data on ZFS is when it warned me that the disk was silently given me bad data back because of its end-to-end checksumming, and I didn't have a mirror). UFS, ext3, ext4 would have continued on giving me bad data back. Are there going to be cases whereby a file system fails completely? Yes, but writing tools to attempt to fix those issues that happen once in a million times is almost impossible because of the difficulty of replicating those failure scenarios and then writing code to deal with the disks having that corruption. I still trust ZFS with more data than any other file system.
