Hi, I wanted to use direct IO with sgp_dd. I have done: echo 1 > /proc/scsi/sg/allow_dio sgp_dd if=/dev/sg1 of=/dev/null bs=512 bpt=128 thr=8 time=1 count=5M dio=1 time to transfer data was 2.236290 secs, 1200.36 MB/sec 5242880+0 records in 5242880+0 records out Direct IO requested but incomplete 40960 times What does it mean "Direct IO requested but incomplete 40960 times"? And what could be the reason for this? When using bpt smaller then 128 it doesn't happen.
