One nit to pick also. Why put /swap on the RAID array? I'd advocate having two separate non-RAID /swap files on the bare metal. But then, that's just me. /swap is slow enough compared to main memory but then you also want to write that transient data again to another drive and slow the rest of the system down, again? Sure modern systems are fast but I look at it as unneeded wear and tear.
Well... on a side note and it doesn't help the OP but... it does make sense to put swap on RAID.
Say a disk dies. Yay, keeps on running because you have the 2nd disk in the array (let's suppose RAID1). But if you have something in swap your system will crash when it loads the swapped-out pages into memory again, because the swap isn't on RAID (supposing the "dead disk" is also full of bad blocks).
Having swap on RAID means that the system actually keeps on running when a disk dies as the swapped out pages will be read from the clean disk in the degraded array.
