Revision as of 14:50, 12 May 2006
This is page contains information about the 4 node PPC (Pegasos) version of Little-Fe.
This version of Little-Fe PPC is based on a Debian GNU/Linux installation. It employs UnionFS to facilitate consolidation of system and cluster software on a single hard drive (attached to lf0). All other nodes netboot from the master image by masking the server-specific files with a lightweight overlay.
lf0can be found atlf-ppc.cluster.earlham.edu

Documentation and bug reporting
- To report a bug, please use Bugzilla
We are documenting the production of Little-Fe in two ways: First, bugs are filed in bugzilla (and hopefully fixed). Second, we're putting flesh on a set of instructions to build a replica of the original Little-Fe PPC. The latter is probably (but not necessarily) based on the former. The distinction is mainly that Bugzilla will show how things were done wrong, while the wiki-based instructions will show how to do things right the first time.
Creating a new Little-Fe PPC
Choose an operating system
Setup the diskless netboot environment
TFTPD
Install a tftp server (Debian's tftpd-hpa is good) and add a line like this to /etc/inetd.conf (or the equivalent in whatever internet "super-server" you use):
tftp dgram udp wait root /usr/sbin/in.tftpd /usr/sbin/in.tftpd -v -s /boot
This runs tftpd and sets its root directory to /boot
DHCPD
Install ISC's DHCPD (e.g., Debian's dhcp3-server package), and setup dhcpd.conf like so:
option domain-name "little-fe-ppc.net";
option domain-name-servers 192.168.1.100;
option subnet-mask 255.255.255.0;
default-lease-time 604800;
max-lease-time 604800;
allow booting;
allow bootp;
subnet 192.168.1.0 netmask 255.255.255.0 {
range 192.168.1.200 192.168.1.254;
option broadcast-address 192.168.1.255;
option routers 192.168.1.1;
next-server 192.168.1.100;
server-identifier 192.168.1.100;
# for client-side union setup
filename "vmlinuz-2.6.15.6 init=/linuxrc root=/dev/nfs ip=dhcp console=ttyS1,115200n1";
option root-path "/client/setup";
# to use server-side union
# filename "vmlinuz-2.6.15.6 root=/dev/nfs ip=dhcp console=ttyS1,115200n1";
# option root-path "/client/root";
use-host-decl-names on;
}
host lf1 { hardware ethernet 00:0B:2F:43:61:EB; fixed-address 192.168.1.101; }
host lf2 { hardware ethernet 00:0b:2f:4f:03:b5; fixed-address 192.168.1.102; }
#host lf3 { hardware ethernet ; fixed-address 192.168.1.103; }
subnet 192.168.10.0 netmask 255.255.255.0 {
range 192.168.10.200 192.168.10.254;
option broadcast-address 192.168.10.255;
use-host-decl-names on;
}
host lf1-eth1 { hardware ethernet 00:0b:2f:62:49:d1; fixed-address 192.168.10.101; }
host lf2-eth1 { hardware ethernet 00:0b:2f:6e:6b:7b; fixed-address 192.168.10.102; }
#host lf3-eth1 { hardware ethernet ; fixed-address 192.168.10.103; }
NFSD
If you're using Debian, use the nfs-kernel-server package (not the nfs-user-server package). (Knowledge about how this translates to other platforms would be helpful here.)
