LONG story short, needed to migrate 4x1TB soft raid to 4x2TB soft raid and I wasn't able to all 8 plus OS drive in the server. After looking for a few bootable live CD's, and NAS distro's to try to get the old RAID back up and running to transfer the data to the new raid. Finally had a 'DERRRR' moment and PXE booted a PC as an MD and set the old raid up to migrate the data back to the server. So, Just an idea, but maybe it would be a good idea to have options when creating a new MD; eg: What do you want this PC to be? NAS, Squeeze-Slave pc, etc.. and then just run the appropriate script and extract the base image to the created diskless dir.
