I haven't played w/ betreplay in quite some time - years actually. In any event, I seem to recall you needed to explicitly enable btreplay to fire off writes : btreplay --write-enable - did you have that flag? I'll try to get some time today to resurrect it to see if it still even works(!) :-) I do know that Jens Axboe's 'fio' program does replay blktrace traffic (see fio read_iolog for example).
