Hi, I am playing with the dedupe option and while it works well under synthetic tests, it doesn't seem to work when replaying a trace. My test jobs are simple: fio --name=replay --ioengine=libaio --direct=1 --iodepth=32 --read_iolog=/path/to/trace --dedupe_percentage=80 or fio --name=synth --ioengine=libaio --direct=1 --iodepth=32 --dedupe_percentage=80 --rw=write I understand that block sizes would be variable during a trace replay, but is it possible to specify a base block size and calculate dedupe based on that for blocks that are multiples of the base size?
