FIO hangs when executing following profile

[wangyihanlarry]

Hi,

I met an issue when running FIO with following profile, it is supposed to stop at 600S, but it hangs for one day, do u you know how to check the reason for the IO hang?

[global] ioengine=libaio exitall_on_error=1 invalidate=1 direct=1 runtime=600 allow_file_create=0 refill_buffers=1 group_reporting iodepth_batch_submit=2 iodepth=16 [vdn-10G-comp57%] filename=/dev/vdn size=10G bsrange=8k-256k do_verify=1 verify=crc32c verify_fatal=1 verify_dump=1 rw=randwrite buffer_compress_percentage=57% buffer_pattern=0x3aec975b [vdn-10G-comp15%] stonewall filename=/dev/vdn size=10G bsrange=4k-128k do_verify=1 verify=crc32c verify_fatal=1 verify_dump=1 rw=randwrite buffer_compress_percentage=15% buffer_pattern=0xbe485319 buffer_compress_chunk=2k

Checked with iostat and found the IO should actually stopped
