Is this a copy and paste from the actual output?  If not, posting the actual 
output may help.

There's nothing wrong with your raidtab, unless those semi-colons are 
actually part of the file and not garbled HTML.

Are the partitions mentioned under the device section of the raidtab in use 
when you try to make the raid array?  What is their partition type?  What 
drive did you boot from to issue the mkraid command?  What is the current 
contents of your /etc/fstab?

What is the contents of /proc/mdstat?

sda1 is a swap partition  and im 100% sure that isnt being used   (I have 2 gigs of ram hehe)

sda2 is being used   thats what I boot from ... but  .. what else can I do ?    the error  is on sda1 ..

/etc/fstab     = below ..

# /etc/fstab: static file system information.

I booted from sda     and thats where i running mkraid from.  Do I need to run it on a floppy or something?

on boot I got this ..

Thanks.

UPDATE :    ok I did swapoff -a     (turns the swap off and it let me mirror the swap partition)

:0)  

but  now   i try to do  the 
 main partition    sba2    and it says device is busy ..

I went into   ini1  (I think thats one user mode)   and it still did it...
