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.
They are? They are being told that the problems they are having
is due
to that but there is no proof. It could be a bad driver for example.
Or a bad cable, or a bad controller IC, or a bad cache RAM. Or
something.
The point is, the entire path from the disk to the main system memory
is the error domain. ZFS sits at the top of this domain and thus can
detect and correct errors that something lower in the domain can not.
Right on. Many people don't seem to grasp this yet.
