The whole raid does not fail -- we are talking about corruption
here. If you lose some inodes your whole partition is not gone.
My ZFS pool would not salvage -- poof, whole thing was gone (granted
it was a test one and not a raidz or mirror yet). But still, for
what happened, I cannot believe
While other file systems, when they become corrupt, allow you to
salvage data :-)
They allow you to salvage what you *think* is your data.
But in reality, you have no clue what the disks are giving you.

I don't think that the issue here, it's more one of perceived data
integrity. People who have been happily using a single RAID 5 are now
finding that the array has been silently corrupting their data.
Hi Betsy,
Yes, part of this is a documentation problem.
I recently documented the find -inum scenario in the community version
of the admin guide. Please see page 156, (well, for next time) here:
http://opensolaris.org/os/community/zfs/docs/
We're working on the larger issue as well.

Well, I fixed the HW but I had one bad file, and the problem was that ZFS
was saying delete the pool and restore from tape when, it turns out, the
answer is just find the file with the bad inode, delete it, clear the device
and scrub. Maybe more of a documentation problme, but it sure is
