I just tried to upgrade OS X Snow Leopard Server to Lion Server on my Mac Mini. The Mini was running a striped RAID 0 of 2x 500GB drives. I had to reformat my drives to allow Lion to install properly. Which has now been done. The problem that I'm now facing is that when I boot into recovery mode (onto the disk's partition where Lion stores the recovery files), Disk Utility tells me that it can't unmount the drives to allow for a RAID set to be generated. Am I doomed to live with 2x 500GB under Lion? Any suggestions???? Do I need to generate some sort of external Lion install drive? If so, how??? help.
