4. Array Configuration

4.1. Building the Array

Add the second hard drive to the card, and turn on your computer. Go into the card bios, and create a mirror array, selecting the appropriate source disk. Make sure you Create and Build the array. After that is done, follow the instructions of the next section.

4.2. Changing Configuration Files

Choose "LinuxFromRaid" Option at LILO.

It should boot up without any errors. It will, however complain about swap. Ignore that, as we will fix it in a moment.

You may receive an error about incorrect module version, or a kernel mismatch. Please see the "troubleshooting" section about this.

After we have booted up on the new system, we must edit a few files:

• /etc/lilo.conf

• /etc/fstab

boot=/dev/sda
map=/boot/map
install=/boot/boot.b
prompt
timeout=50
message=/boot/message
linear
default=LinuxFromRAID

image=/boot/vmlinuz-2.4.2-2
        label=linux
        read-only
        root=/dev/hda5

image=/boot/vmlinuz-2.4.2-2
        label=LinuxFromRAID
        initrd=/boot/initrd-2.4.2-2.img
        read-only
        root=/dev/sda5

/dev/hda2               swap                    swap    defaults        0 0
