Squeeze FAI+PXE installation

From WikiOAR

This should work for a Dell server having Broadcom Netxtreme II interfaces that needs non-free firmware to boot correctly.

FAI install and dhcp config

• apt-get install fai-quickstart
• cp /usr/share/doc/fai-doc/examples/etc/dhcpd.conf /etc/dhcp/dhcpd.conf
• vi /etc/dhcp/dhcpd.conf
• /etc/init.d/isc-dhcp-server restart

Customization for squeeze (FAI installs only lenny at the moment of speaking)

• /etc/fai/make-fai-nfsroot.conf :

set FAI_DEBOOTSTRAP="squeeze http://ftp.fr.debian.org/debian"

• put into /etc/fai/apt/sources.list:

deb http://security.debian.org/ squeeze/updates main
deb http://ftp.fr.debian.org/debian squeeze main contrib non-free

Run fai-setup

fai-setup -v

It exits ok, but with an ERROR:

ERROR: live-initramfs was not installed inside the nfsroot.

Well, anyway, we have to make our own initrd.img, so...

Initrd customization

• chroot /srv/fai/nfsroot/live/filesystem.dir
• apt-get install firmware-bnx2
• vi /etc/initramfs-tools/modules : add "bnx2"
• rm /boot/initrd.img-2.6.32-5-amd64
• update-initramfs -k 2.6.32-5-amd64 -c
• exit (from the chroot)
• cp /srv/fai/nfsroot/live/filesystem.dir/boot/initrd.img-* /srv/tftp/fai/

Still doesn't work... aufs fix!

• chroot /srv/fai/nfsroot/live/filesystem.dir
• Apply this patch to /usr/share/initramfs-tools/scripts/live

http://grml.org/patches/0001-workaround-aufs-issue-in-kernel-versions-around-2.6..patch

• re-run update-initramfs -k 2.6.32-5-amd64 -c
• exit from chroot and copy the initrd into /srv/tftp/fai/

Add /srv/fai/config to NFS exports

• Edit /etc/exports and add missing line like this:

/srv/fai/config 152.77.100.2/28(async,ro,no_subtree_check,no_root_squash)

Start the install

• fai-chboot -IFv killeen
• ipmitool -H killeen-bmc power reset
• After the install, normal boot: fai-chboot -dFv killeen

More FAI configuration

Proxy-cache during and after install

• vi /srv/fai/nfsroot/live/filesystem.dir/etc/apt/apt.conf.d/proxy

Acquire::http::Proxy "http://www-cache.ujf-grenoble.fr:3128";

• vi /srv/fai/config/scripts/LAST/50-misc

# add this line at the end:
fcopy -i /etc/apt.conf.d/proxy

Custom packages

• create a class (ie CIMENT) by editing /srv/fai/config/class/50-host-classes :

   *)
       echo "FAIBASE DHCPC CIMENT" ;;

• create a file /srv/fai/config/package_config/CIMENT
