Hi chenxiang:
We've meet this issue before,and we've discussed with some disk experts, for HDD,if you run fio, the write/read operation may start at any LBA, for example LBA = 0,and when the LBA reach the max ,the fio will stop normal,and the fio status change to "_" ;
If there is something wrong happened, the fio status will change to "X";
You can control this with the parameter of "time_based", if you set time_based = 1, the fio will run as long as you defined with the parameter of "run_time".
Ok, thanks.
Thanks

Hi Jens,
When i use fio to test 4k READ for 19 disks which are connected with a
expander, and find a issue:
the numbers of jobs decrease after some times, after about 2 days or 3
days, there is only one job
left, but there is no another exception. Part of log is as follows (the
attachment is the script i use to run fio
(./creat_fio_task.sh 4k read 64)):
Did you mention the fio version anywhere? If not, it may be helpful info.
