Hi, I ran a read workload through FIO and collected blktrace for it. I got like 15 trace files one for each CPU core with varying sizes. Question 1: how would I know which CPU core trace file to use to run a replay ? Blkparsed a particular cpu core file trace to a .bin and tried replaying in FIO . When I replay in FIO using read_iolog=/root/blktrace6.bin , I get the below error. Replay: (groupid=0, jobs=1): err=22 (file:engine/sync.c:45, func=lseek, error=invalid argument): pid: 12816 Question2: please help me understand what is the reason for this error ?
