Hmm...

I think the offsets in the log messages are in _bytes_. The stripe size is 128k
_bytes_. So the 157622337536-th byte is in the 1202563-rd stripe from the point
of view of the geom_stripe and the [1202563/32]-th stripe on the underlying
disk and the disk# should be [1202563%32].

I dont see why/where ur 16k come into the computation...
