The Setup
My first setup is a cluster of 2 Pentium II based machines
interconnected with 10Mbit Ethernet and a HUB in between.

As you can see I only had a 10Mbit network to perform these test, so
these tests were far from being ideal. Anybody out there would care
of lending me a 100Mbit Switch plus network cards for a couple of
days?
I quickly installed RH 8.0 on the machines together with the following
RPMs:
[root@inspon root]# rpm -qa | grep openmosix
openmosix-tools-0.2.4-1
openmosixview-1.4-redhat80
openmosix-kernel-2.4.20-openmosix2 |
I also used omdiscd for the initial setup of the cluster: this way I
quickly had all my nodes up and running without having to create an
/etc/openmosix.map file. And I created oMFS mountpoints and enabled them
by adding:
mfs_mnt /mfs mfs dfsa=1 0 0 |
to /etc/fstab and running mount -a
