Hello,
I was attempting to remove 1 disk from a 4 disc raid to copy the data off it and destroy the raid completely. But instead when i clicked delete, the raid was destroyed. I still have both halves of it. (Two sets of two drives with mirrored data or the striped raid). How can i tell mac os x leopard to take these two "mirror sets" and put them into a striped set?

this was a raid 10

i presume something using:
diskutil command
createRAID mirror|stripe|concat setName format devices ...
Create a new RAID set consisting of multiple disks and/or RAID
sets. setName is used for both the name of the created RAID
volume and the RAID set itself (as displayed in listRAID).
e.g. 'diskutil createRAID stripe MyArray JHFS+ disk1 disk2
disk3 disk4'. Ownership of the affected disks is required.

diskutil listRAID returns:

edit:
I rebooted and disk utility is showing me this.
I then clicked on one of the raid groups and made it look like the screenshot, however when i click create it wants to erase all the data, this isn't what i want.

Any ideas?
