Run states

Live CD

• Defaults

Either

• Shared software:
  • Node 1: linux startdhcp startnfs dhcp_masterserver=A.B.C.D.
  • Node 2: linux masterserver
  • Make sure node 2 has the mount:

 none on /UNIONFS/cluster/software type aufs (ro,br=/mnt/192.168.2.5//cluster/software/=ro:/cluster/software=ro)

• Custom router:
  • Node 1: linux startdhcp dhcp_router=A.B.C.D.
  • Make sure this ends up in /etc/dhcp3. You should see the router option in dhcpd.conf set to A.B.C.D.
• Custom router based on NIC:
  • Node 1: linux startdhcp dhcp_routernic=ethn
  • Make sure this ends up in /etc/dhcp3. You should see the router option in dhcpd.conf set to A.B.C.D.
• Custom IP information:
  • Node 1: linux nics=ip0/mask0:ip1/mask1
  • Make sure the node has this information in /etc/network/interfaces and ifconfig.

Liberated

1. Liberate: perl /root/liberate.pl --libdev=/dev/dev
2. Reboot.
3. Start with DHCP services: linux startdhcp startnfs allowpxe
4. Boot other cluster nodes after boot up.

Troubleshooting

1. If zlib compression failures swamp the console when you try to liberate, this probably means you're using a scratched livecd disc.
2. Wipe the disc clean and try again.
