Moving Users Directory to Raid 1

Question

Hi all,
I'm going to install a Raid 1 system with two WD1500KS.
I'd like to put the full existing Users directory onto this Raid 1.
One question about Raid 1 system, is there a Master and a Slave ? What appear on the screen , a disk called Raid 1 and the system manage the distribution or we can see the two drives composing Raid 1 ?
There was discussions about how to move Users directory to another Volume :

After reading again and again these posts, where Ned, Steve and The Hatter have proposed solutions for this move, I'm lost and thinking as Ned's solution has not yet been deployed, and Steve's one seems easy but could be problematic with some applications according to Ned, I'm still uncertain about what should I do ?
Could you please tell me if Steve's solution :
"For this example, assume that you have a drive called disk2, accessible at /Volumes/disk2. This is more steps than required, but it is a safe way to accomplish the task.
1) Back up your users directory.
2) Create a new users directory on the target disk:
sudo mkdir /Volumes/disk2/Users
3) Set permissions appropriately on new directory:
sudo chown root:admin /Volumes/disk2/Users
4) Copy data from existing Users directory to new Users directory:
sudo cp -Rp /Users/ /Volumes/disk2/Users/
* note: make sure you use the switches shown (-Rp); this does a recursive copy, and duplicates the permissions of the copied files.
* note: make sure you add the trailing backslash!
5) Rename the existing Users directory to be extra paranoid:
sudo mv /Users /UsersBackup
6) Create a symbolic link pointing to the new Users directory:
sudo ln -siv /Volumes/disk2/Users/ /Users
It wouldn't hurt to restart at this point.
Once you are satisfied that everything is present on the new drive, you can delete the extra paranoid backup we made in step 5:
sudo rm -rf /UsersBackup
Enjoy "
is problematic for Users directory or only as The Hatter mentionned for Applications directory :
"Trying to use a symbolic link to relocate /Applications, and especially Apple programs is where there was usually trouble."
Thanks,

Answer 1

Done,
Used Ned's and Steve's methods:
1 - Create "Users" directory onto Raid 1 system
2 - Copy all from Volume/Raptor/Users directory to Volume/Raid1/Users/
3 - Activate Root User with Netinfo Manager
4 - Modify all users "Home address" into Net info Manager and save
5 - Reboot, log into my account and "You are unable to log in to the user account" message, even with administrator account.
6 - Reboot onto old OSX partition, wonder what could be the reason ? IMHO it could be only my mistake (Peloche's method), may be typing error within the "Home address", change Raid name from "Raid1" to "Raid 1"
7 - Reboot onto Raptor, log to my account and OK it works
8 - Use "sudo mv /Users /UsersBackup"
9 - Reboot OK
10 - Copy all my "Documents" from "UsersBackup" to another partition
11 - Reboot OK
12 - Use "sudo rm -rf /UsersBackup"
13 - Reboot OK
14 - Thanks to Ned and Steve
