Here's how I did it:
1.) Download the MOSIX 1.9 2.4.20 patch from here:
http://www.mosix.org/txt_distribution.html
2.) Download the MOSIX 1.9 user level Tools from that same site
3.) Patch your 2.4.20 kernel with the MOSIX 1.9 patch
4.) Config the MOSIX option with
[x] MOSIX process migration
[x] MOSIX file system
5.) Compile and install your new kernel. Reboot.
6.) Install the MOSIX 1.9 user level Tools (do a manual install according to the README)
7.) Copy the mosix.init script to /etc/rc.d/rc.mosix.
8.) Make your mfs dir. (#mkdir /mfs)
9.) Edit your /etc/fstab by adding:
mymfs /mfs mfs defaults 0 0
10.) Start MOSIX (#/etc/rc.d/rc.mosix start)
11.) MOSIX will prompt you to create your mosix.map file. Add your nodes as follows:
1 192.168.1.1 1
2 192.168.1.2 1
etc.
12.) Start MOSIX again. You should see "Initializing MOSIX..."
13.) Install MOSIX on your other node(s) in the exact same way with the exact same kernel version and MOSIX patch/user level tools (otherwise, and I guarantee you, MOSIX will not work!)
14.) Reboot your machines. Pull-up a terminal and do #mon. You will see a
bar-graph monitor of all machine nodes.
15.) Peruse /mfs/node-number to access the filesystems on your other nodes.
16.) Enjoy!
It wasn't really that difficult. I actually have a Gentoo box on the second node and the Slack9 box on the first node, so you can mix-and-match distros as long as you maintain the same kernel+MOSIX versions.
Good luck!
