Sandro, >From within grub, you can do > install (hd0,0)/grub/stage1 (hd1) (hd1,0)/grub/stage2 (hd0,0)/grub/menu.lst to write the boot sector from hd0 to hd1 without a floppy. However, you will need to do this again to any replacement disks added to the raid-1, and if the primary disk's boot info gets corrupted, grub won't automatically switch to the mirror/secondary, you'll have to physically remove the corrupted disk. Does anybody know if/when the grub project will add raid support?

I always use GRUB for Raid1 setup with boot partition an md device, and I'm beginning to think I'm using it the wrong way! What I do is I 'setup' the partitios from a floppy: title Install GRUB into (hd0,0) the first disk root (hd0,0) setup (hd0) title Install GRUB into (hd1,0) the second disk root (hd1,0) setup (hd1) Both partitions (hd0,0) and (hd1,0) are part of /dev/md/0 At that point I'm able to start from both devices... BTW I've never been able to do that w/o passing from a floppy. If I do that from the CD I use to install everithing seems OK but it doesn't boot. -- Sandro Dentella *:-) e-mail: sandro.dentella@tin.it http://www.tksql.org TkSQL Home page - My GPL work - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
