I am trying to parallelize my rsync calls using gnu-parallel as shown below. But whenever I run my below script, it looks like it doesn't copy anything at all. But I do see lot of rsync processes (ps aux | grep rsync) running so not sure what's wrong here:

export PRIMARY=/data01/test_primary
export SECONDARY=/data02/test_secondary
export dir3=/bat/data/snapshot/20180227
PRIMARY_FILES=(685 959 682 679 688 651 909 906 657 881 884 878 853 707 847)
SECONDARY_FILES=(950 883 887 890 1001 994 997 1058 981 833)

export LOCATION_1="machineA"
export LOCATION_2="machineB"
export LOCATION_3="machineC"

do_Copy() {
  el=$1
  PRIMSEC=$2
  rsync -az golden@"$LOCATION_1":"$dir3"/proc_"$el"_5.data "$PRIMSEC"/. || rsync -az golden@"$LOCATION_2":"$dir3"/proc_"$el"_5.data "$PRIMSEC"/. || rsync -az golden@"$LOCATION_3":"$dir3"/proc_"$el"_5.data "$PRIMSEC"/. || exit 1
}
export -f do_Copy
parallel -j 5 do_Copy {} $PRIMARY ::: ${PRIMARY_FILES[@]} &
parallel -j 5 do_Copy {} $SECONDARY ::: ${SECONDARY_FILES[@]} &
wait

echo "All copied."

Is there anything wrong I am doing here?
