I'm not sure if this is a bug or a documentation glitch, but I'm getting an extra 11 values when using terse output. Based on the sum of the numbers it appears that it is generating data for both usec and msec as opposed to the expected "<=2, 4, ..., 1000, >=2000" break down detailed in the man page. Unfortunately this also means I don't know what the values of the fields are... The output was generated with: "fio --name="write-64-8-2" --ioengine=libaio --file=$DEVICE --direct=1 --bs=8k --numjobs=64 --iodepth=1 --size=4096m --group_reporting --minimal" 1xSSD-write-64-8-2;0;0;0;0;0;0;0;0.000000;0.000000;0;0;0.000000;0.000000;0;0;0.000000%;0.000000;0.000000;8388608;331811;25888;6;11639;92.527601;27.001639;1;20834;1484.959225;253.256387;0;13254;1.528887%;5073.016621;172.144842;0.341511%;1.632573%;1202192;0;449;100.0%;0.0%;0.0%;0.0%;0.0%;0.0%;0.0%;0.01%;0.09%;0.01%;0.01%;0.03%;0.06%;0.08%;0.51%;4.57%;78.44%;5.03%;3.41%;5.11%;2.67%;0.01%;0.00%;0.00%;0.00%;0.00%;0.00%;0.00%;0.00% In this case the last 22 fields sum to 100.04%, the 0.04% being a reasonable rounding error. I seem to be consistently getting these results on any RHEL5 system using the Fio RPM from Dag or compiled from source.
