Leaving aside the ondisk/onpart issue which has been answered, I see you
are keeping the swap partitions as individual devices.

I prefer to raid1 the swap as well, just like the filesystems. If you lose
a disk and some memory is swapped out to the failed disk, your system will
very likely crash. If swap is mirrored too, the disk failure should not
crash the system, since the same data is on the working disk.

Cheers
Tony
