... If the block checksums
show OK, then reading the parity for the corresponding data yields no
additional useful information.
It would yield useful information about the status of the parity
information on disk.
The read would be done because you're already paying the penalty for
reading all the data blocks, so you can verify the stability of the
parity information on disk by reading an additional amount.
Sounds like this additional checking (I see your point) could be
optional?
