Message-ID: <555D9487.3040104@cnnic.cn> (raw)

hi all~
     I wanted to use fio to test random write performance, the command 
line is as forllowing:

       fio --filename=/dev/sdb1 --direct=1 --iodepth 1 --thread 
--rw=randwrite --ioengine=psync --bs=16k --size=200G --numjobs=10 
--runtime=1000 --group_reporting --name=mytest

     After the execution of fio finished, my disc usage become 100%, is 
there any method to release the content written by Fio?

  Thanks a lot in advance!!
