IRIDIA cluster installing nodes with disks
From IridiaWiki
Fully Automated Installation (FAI) is the package used to install the nodes with disks (the rack nodes).
Installing FAI
apt-get install fai
Create a user called "fai".
You have to edit the three files:
/etc/fai/fai.conf /etc/fai/sources.list /etc/fai/make-fai-nfsroot.conf
In those directories you have to setup items like where the image directory should be located, local servers, apt sources etc.
Then you should run:
fai-setup
And if everything goes as planned, you will get lots of warnings and a message saying that image creation was successful at the end.
