Hi. In attempting to get a single job to create files before allowing further jobs to perform I/O on them, I cannot see how to restrict the sum total of all the files on the device. I wish to create n files ranging in size from i-j with a cap of m in total (so the sum of n does not exceed m). For example; [file-generator] numjobs=1 create_only=1 create_on_open=0 time_based=0 fill_fs=0 fill_device=0 filesize=4k-20m size=512m nrfiles=256 fallocate=posix fadvise_hint=1 filename_format=\$filenum.dat directory=/tmp/fio I'd expect the above to create 256 files ranging from 4k to 20m and a 'du -sh' on /tmp/fio to result in 512m. However, it always seems to fill the device! How can I stop this?
