Hello Everyone, It's been a stretch since I last did something that required logging logging, that would be going from 2.0 to the latest git clone from today. When I tried to use my older fio configuration files with the new fio it barked about not specifying the write_bw_log name. The 2.0.x version used the name from the job so you could have the options turned on in [global]. Is the change in behavior where you now have to specify the name of the log (thus requiring it to be in each job) intentional? fio 2.0.x config [global] direct=1 ioengine=libaio zonesize=256m zoneskip=768m randrepeat=1 write_bw_log write_lat_log ; [sda-iodepth1-write-bs1k-1] stonewall filename=/dev/sda iodepth=1 rw=write bs=1k runtime=45s time_based ramp_time=15s fio 2.1.x git from today [global] direct=1 ioengine=libaio zonesize=256m zoneskip=768m randrepeat=1 ; [sdc-iodepth8-write-bs128k-1] stonewall filename=/dev/sdc iodepth=8 rw=write bs=128k runtime=45s time_based ramp_time=15s write_bw_log=sdc-iodepth8-write-bs128k-1 write_lat_log=sdc-iodepth8-write-bs128k-1 write_iops_log=sdc-iodepth8-write-bs128k-1 Thanks, Roger -- 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
