      There is a test util aiocp under lustre/tests directory. If use this util to copy a file from latest Lustre (tag: v2_16_51), in DIO mode , it reports errno 22: Invalid Argument.

      # aiocp -f DIRECT /mnt/lustre/d1/f1 ~/1
read missed bytes at 0 expected 2736 got -22

      Remove the flag -f DIRECT, it succeeds.

      # aiocp  /mnt/lustre/d1/f1 ~/1
# echo $?
0
