So far we've tested this build on one machine, using the below
comparison 30+ times, and it looks good.
# i=0; while :; do i=$(($i+1)); echo -n "." ; dd if=/dev/urandom
of=test.dat bs=1G count=8 iflag=fullblock ; dd if=test.dat of=/dev/hioa
bs=1G count=8 iflag=fullblock ; dd if=/dev/hioa of=read-back.dat bs=1G
count=8 ; cmp=$(md5sum test.dat read-back.dat|awk '{print $1}'|sort
-u|wc -l); if [ "$cmp" -ne 1 ]; then echo "MISMATCH" ; md5sum test.dat
read-back.dat ; echo $i; return 1; fi; done
