Ok. Then making a mirrored / (root) partition, according to RAID HOWTO...
- Make partitions on the (empty) mirrordisk - Make the partition type to RAID (8e?) - Make filesystems, mount as raid - Copy all files to the mirrordisk. - Make the nessesary changes in Silo.conf, fstab, raidtab etc. on the mirrordisk - Install Silo on mirrordisk - Boot up on the mirrordisk (which is configured as RAID?) - Change the state in RAID of the orginal disk from "broken" to "good" QUESTION1: Is this the preferable way to do it??? Or are there any easier way??? ( I only have to disks ) QUESTION2: Can (anybody) show me a good example of the silo.conf with RAID configured. ( Some of the options in the Boot+Root+RAID+Lilo HOWTO doesn't work in silo, which makes me chick-out :-) QUESTION3: Should or could i mirror the /boot and swap? RAID HOWTO doesn't recommend mirroring the swap, so i that maybe answers half the question... Well, heres some info on my system: Sparc 5. to internal disks... SuSE dist version i'm running is 7.3. The kernel version is the included 2.2.20 with RAID support compiled in staticly. fdisk -l /dev/sda looks like this: Disk /dev/sda (Sun disk label): 16 heads, 135 sectors, 3880 cylinders Units = cylinders of 2160 * 512 bytes Device Flag Start End Blocks Id System /dev/sda1 0 24 25920 83 Linux native /dev/sda2 u 24 267 262440 82 Linux swap /dev/sda3 u 0 3880 4190400 5 Whole disk /dev/sda4 267 3586 3584520 83 Linux native /dev/sda5 3586 3880 317520 83 Linux native And mounted like this: /dev/sda1 is /boot /dev/sda4 is / (root) /dev/sda5 is /var (just say if you need more info from me...)
