you're randwrite to a raw partition. if you had a filesystem on that
partition you were trying to use, then well, your data is gone/corrupted.
without a filesystem on it, i'm not sure how you'd think that your disc
usage has become "100%" without some xgui widgit warning you, so seems
likely you did something you didn't mean to with regards to writing to
/dev/sdb1 directly
if you use fio on devices/partitions with a filesystem, you need to have
it write to files or it will trash your filesystem

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!!
