I used the same workload: # fio --name=test_job --ioengine=libaio --direct=1 --rw=write --iodepth=32 --size=100% --numjobs=1 --bs=1m --filename=/dev/nvme0n1 --group_reporting --write_bw_log=test_job --write_iops_log=test_job --write_lat_log=test_job --log_avg_msec=1000 --disable_lat=0 --disable_clat=0 --disable_slat=0 --runtime=1500s --time_based --ramp_time=5s --output=test_job For whatever reason, looks like gdb truncates the parameters.
