Depends on what the job looks like. If you stick to writing to files in a mounted fs, it'll work fine. If you tell fio to use --filename=/dev/sda or whatever the device is, you'll corrupt the file system(s) if that job file is doing writes. -- Jens Axboe -- 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
