Do you know how close to the data the zfs checksum is stored? Is it possible that one FS block read will actually result in two seperate physical IO's, one for the data, one for the checksum?
I don't know exactly where the zfs checksum is stored except to know that there are several copies of the checksum stored on each mirror disk, and they are in different data allocations than the user data blocks.
