Hi Guys-- OK, here's what I have... hopefully someone out there has had this experience. Here at work we have a G5 (Dual 1.8) with a single 80GB Seagate Drive in it. We use this G5 as our webserver. We would like to add another 80GB drive to it (easy enough) and set the two drives to a RAID 1 or mirrored array, in case one fails. The only time I have created a RAID 1, I had to initialize both disks, in a sense, blasting all information on them to nothing. Is there a way to create a RAID array without initializing the (already in use) system drive? Can I create a RAID and rebuild it without starting from scratch? If there isn't a way, what's the best way to backup this entire system so that we can place it on the RAID after the RAID is created? I can't go through re-installing the system and apps, because our webserver has all of these different settings and preferences that I don't want to have to re-create. It would be very messy. Any ideas would be most helpful. Thanks All!
