IRIDIA cluster installing nodes with disks

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.

Make the appropriate adjustments to the files in:

/usr/local/share/fai/ 

(check fai documentation on how to do this).

On polyphemus add the user fai, with home in /mnt/disk1/fai to keep logs of installations of the rack.

Remember to update

/etc/dhcpd.conf

to deal with the rack clients on majorana.
