I have a workload to write 10m to a file in a pattern or 1's and 0's alternatively for each pass. I used stonewall to write and wait for each job to finish. Everything work fine till i specify runtime and time_based parameters to run the same for a minute. It sees FIO is taking more time than the specified timelines. While running, the output constantly displays a static eta for a long time and then completes Jobs: 1 (f=1): [W(1),P(3)] [13.0% done] [0KB/3527MB/0KB /s] [0/3527/0 iops] [eta 01m:00s] Jobs: 1 (f=1): [_(1),w(1),P(2)] [61.3% done] [0KB/3639MB/0KB /s] [0/3639/0 iops] [eta 01m:00s] Jobs: 1 (f=1): [_(1),w(1),P(2)] [63.9% done] [0KB/3580MB/0KB /s] [0/3580/0 iops] [eta 01m:00s] Jobs: 1 (f=1): [_(2),w(1),P(1)] [71.6% done] [0KB/3644MB/0KB /s] [0/3644/0 iops] [eta 01m:00s] Jobs: 1 (f=1): [_(2),w(1),P(1)] [73.2% done] [0KB/3614MB/0KB /s] [0/3614/0 iops] [eta 01m:00s] Jobs: 1 (f=1): [_(3),W(1)] [78.0% done] [0KB/3582MB/0KB /s] [0/3582/0 iops] [eta 00m:53s] Jobs: 1 (f=1): [_(3),W(1)] [86.7% done] [0KB/3527MB/0KB /s] [0/3527/0 iops] [eta 00m:32s] Jobs: 1 (f=1): [_(3),W(1)] [98.8% done] [0KB/3560MB/0KB /s] [0/3560/0 iops] [eta 00m:03s] Total time taken for the job to complete is: real 4m1.225s user 0m4.816s sys 3m55.760s Without specifying the runtime parameters, the following is the time taken for one pass real 0m1.339s user 0m0.232s sys 0m0.108s # fio -v fio-2.2.7-26-g9451b # cat test1.fio [global] ioengine=libaio size=1m blocksize=1024k,1024k iodepth=8 iodepth_batch=4 iodepth_low=2 ;runtime=60 ;time_based filename=testfile_test1 numjobs=1 [pattern_one_seq_write] buffer_pattern=0xff readwrite=write [pattern_zero_rand_write] zero_buffers readwrite=randwrite percentage_random=100 stonewall [pattern_one_rand_write] buffer_pattern=0xff readwrite=randwrite percentage_random=100 stonewall [pattern_zero_seq_write] zero_buffers readwrite=write stonewall -- Srinivasa R Chamarthy -- To unsubscribe from this list: send the line "unsubscribe fio" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
