-O I've missed:
aiostress -s 1200m -O -o 2 -i 1 -r 16k <test_file>
You are right I've used harness scripts.
i=0; while ((i++<50)); do ~/bm/bin/runs I2 -; done &
It runs bmrun harness script which is long for different hardware
configurations and test options.
The lines in aio-stress wrapper which could be useful for you are:
gcc aiostress.c -Wall -o aiostress -lpthread -laio
2>>${file_log}
...
sudo umount -f ${pdisk} ${ppath} > /dev/null 2>&1
sudo /sbin/mke2fs -j ${pdisk} > /dev/null 2>>${file_log}
sudo mount ${pdisk} ${ppath} > /dev/null 2>>${file_log}...
export LD_LIBRARY_PATH=/lib:/usr/lib:$LD_LIBRARY_PATH
all_files_size=1200 # in megabytes
...
else
num_disks=1
((file_size = all_files_size / num_disks))
testfiles=${ppath}/test/testfile
dd if=/dev/zero of=$testfiles bs=1M count=${file_size} >
/dev/null
fi
aiostress ${*} -v -o 2 -s ${file_size}m -i 1 -r 16k $testfiles >
${file_res} 2>&1
if [ "$1" == "-S" ] ; then
info="O_SYNC"
elif [ "$1" == "-O" ] ; then
info="O_DIRECT"
fi
awk .... ${file_res}
....
Which does
1) mem=1G in kernel boot param if you have more
2) unmount; mk2fs; mount
3) dd if=/dev/zero of=<test_file> bs=1M count=1200
4) aiostress -s 1200m -O -o 2 -i 1 -r 16k <test_file>
5) if i++<50 goto 2).

Sorry, this aio-stress command line doesn't do O_DIRECT. Do you have
this bundled into a test script that I can try?
