You cannot "add" a third to to a two-way RAID1.
You can create a new three-way RAID1 if you want.
But you can't (AFAIK) change the number of disk is the base array.

That is not needed, but is good practice.

Hi
I have a RH6.1 box with two mirrored drives in a RAID1 config.
I am wanting to add a spare disk and would like advice on the correct
procedure for adding it to the existing config.
What I planned was:
1. Bring the system down.
2. Install the spare drive
3. Boot up and edit the /etc/raidtab
