I forgot to include one other thing I wondered about. After I installed the base OS, I wanted to 'test' the mirror so I unplugged the power to one of the disks. The result was FreeBSD panicing, which was not what I expected to see. This was still with 5.2.1 (I'm now up to par with -CURRENT). I would assume the system would continue utilizing the one existend disk, specially after FreeBSD _knows_ the configuration of the raid array. Any comments for this disillusioned raid newbie ? /Stephan
