I asked about this in regards to grub2 the other day. The problem with software raid for me is that when I switch disks the drive order gets messed up every time. The first is that if the first disk fails hd1 becomes hd0 and so on. The other reason is that the onboard chips can't see SATA 2 disks. So if one of the onboard disks fails I have to move disks around to get another SATA 1 disk on the onboard port and free a port on the SATA 2 controler. And then the disk order is usualy scrambled up and grub fails. Now with grub2 you don't have to specify a boot device as (hd0,0) anymore but grub2 will suposedly find the right disk itself. This makes is really interesting for software raid. MfG Goswin -- To UNSUBSCRIBE, email to debian-amd64-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
