Hi, I have installed beta-2 (31082004) on a Supermicro 5013C-T (P4SCE motherboard with ICH5R, and two WD 74 GB Raptor SATA drives, which I want to mirror). I know the ICH5R is not a real raid controller, but I'm trying to get it to work using atacontrol and the built-in RAID1 support. Using the procedure described in http://www.techno-obscura.com/~delgado/notes/fbsd-ich5SATAraid.html (thanks!) I managed to get FreeBSD installed on RAID1 on ar0. Next I tried to remove a drive (atacontrol detach), and even zeroed the first area of the disk. After reattaching the drive, I cannot get atacontrol to rebuild the drive. If I do atacontrol rebuild ar0, it does absolutely nothing. From browsing this mailing list I see that this seems to be a problem with using non-raid controllers, but will this be improved in the future? Or am I doing something wrong? What other options do I have? Is geom-vinum ready for this? All I want is a fully mirrored system (incl root and swap). I could put a simple raid controller in, like the Promise S150 TX2Plus or TX4, but if I can get it to work with the ICH5R controller that would be great. Thanks, Ben
