Hi, I need to simulate a workload of generating sequence of files - some thing like creating photos. where is my config: [global] create_on_open=1 unlink=1 filesize=70m size=7000m [pilatus-sec-write] rw=write openfiles=1 nrfiles=100 stonewall I will expect that a combination of create_on_open and openfiles will create one file at the time, nevertheless all files get created at the same time. Thanks in advance, Tigran. -- 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
