Thanks for the reply. the capacity of the SSD is 850GB, but I am trying to run the workload continuously between 0 and 745GB of the capacity. I would like to workload to be time based so that it continues to run, even if more than 745 GB of data is written, but still within that same range. Is there a method of continuing to run the workload from 0 to 745GB, even if more than 745GB is written?

Not sure how to answer your question more precisely, as you don't mention what LBAs you want your test to be limited to. -- Jens Axboe -- To unsubscribe from this list: send the line "unsubscribe fio" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html -- To unsubscribe from this list: send the line "unsubscribe fio" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
