That's the way parity re-write works. I thought reconstruction worked
differently. oster@?
Reconstruction does not do the "read", "compare", "write" operation like
parity checking. It just does "read", "compute", "write". In the case
of RAID 1, "compute" does nothing ,and it's basically read from one
component and write to the other.
