<accesscontrol>teacher</accesscontrol> Følg guiden her. Har dog ikke fået det til at virke, stopper bare når den skal finde hardware.

Denne er til information: "I've installed hardy server on a dell poweredge 1750--older hardware.

Perhaps you need to initialize your disks via the RAID controller first. Try going into the BIOS (or RAID BIOS Control-S or something similar) and make sure that you have your drives set up the way you want--RAID configuration, hotswap, whatever. Once that is done, then put in the CD and run the "Check CD for errors" to make sure your CD drive can read the entire disk. Server CDROM drives tend to get dirty because of the massive airflow of server machines."

Har også prøvet den her: https://help.ubuntu.com/community/DisklessUbuntuHowto
Og den her: https://help.ubuntu.com/community/Installation/OnNFSDrive

Men det virker ikke helt efter hensigten endnu.

Installation af Lucid der kan boote fra NFS

Opret en folder til installatinen, her har jeg valgt /var/nfsroot
Derpå laver vi en debootstrap med lucid i folderen fra et ubuntu mirror.

debootstrap --arch i386 lucid /var/nfsroot http://mirrors.dotsrc.org/ubuntu/

Tilføj nogle mirrors til den nye installation. Så /var/nfsroot/etc/apt/sources.list ser ca sådan ud.

deb http://mirrors.dotsrc.org/ubuntu/ lucid main restricted
deb-src http://mirrors.dotsrc.org/ubuntu/ lucid main restricted

chroot ind i /var/nfsroot

chroot /var/nfsroot

Slå initctl fra imens man arbejder på installationen(Så tjenester ikke starter)

#dpkg-divert --local --rename --add /sbin/initctl
perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
        LANGUAGE = (unset),
        LC_ALL = (unset),
        LANG = "en_DK.UTF-8"
    are supported and installed on your system.
perl: warning: Falling back to the standard locale ("C").
Adding `local diversion of /sbin/initctl to /sbin/initctl.distrib'
#ln -s /bin/true /sbin/initctl

Opdater installationen

aptitude update
aptitude dist-upgrade
#Installer kernen
aptitude install linux-image-server

Mount proc

mount -t proc proc proc

Ændre i /etc/initramfs-tool/initramfs.conf så BOOT=nfs
Opdater initramfs

update-initramfs -u

så skal iniramfs disken og kernel smides på TFTP og pxe boot filen med:

label ubuntulive
        menu label Ubuntu Server 10.04 NFS
        kernel ubuntu/live/vmlinuz-2.6.32-25-generic-pae
        append root=/dev/nfs initrd=ubuntu/live/initrd.img-2.6.32-25-generic-pae nfsroot=172.16.4.83:/var/nfsroot ip=dhcp rw

Sætte eth0 op i /etc/network/interfaces

auto eth0
iface eth0 inet manual

Sæt evt en fast ip:

auto eth1
iface eth1 inet static
        address 10.0.0.1
        netmask 255.255.255.0
        network 10.0.0.0
        broadcast 10.0.0.255

Ændre hostnavn til WorkerNode

nano /etc/hostname
WorkerNode

System services

Installerne nu gængse services. Bemærk: Installationen booter ikke op til prompt, derfor installeres ssh server så man kan ssh til den.

aptitude install -y openssh-server openmpi-bin openmpi-dev bmon nfs-common nano
