Then create a file .../fai/disk_config/PARTITION1 , which will automatic used by host E and F. case $HOSTNAME in B|D) echo X1 ;; E|F) echo PARTITION1 ;; esac For the base system, which is used by all hosts, you can use the class ANY.

RE: upgrade
Hi, I had the following question regarding FAI - something which I havent been able to understand from the documentation: Where and how do you specify which hosts are in which classes? for example if A and C have the same network card and B and D have to have a certain package and E and F have to have a certain partition structure but all ABCDEF have the same base system, its still not clear to me how to do this with classes. Can anyone help by giving me an example?

RE: upgrade
Hi, there's this long rcS_fai script that calls install_packages and defines all environment variables, that are needed. FAI_ROOT and classes must be defined maybe other too. fai has no mechanism to call a command on every node of a cluster (push method), it uses a pull method, so every node get it's command to execute. For upgrading you do not need fai. Try this little script #! /bin/csh set clustername=node foreach h (01 02 03 04 05 06 07 08 09 10 11 12 13 14) set host = $clustername$h ping $host 1 >/dev/null if ($status == 0) then echo '' echo '' echo '* '$host' *' rsh $host apt-get update rsh $host apt-get -f -y upgrade endif end -- Thomas -- Thomas Lange Institut fuer Informatikmailto:[EMAIL PROTECTED] Universitaet zu Koeln Pohligstr. 1Telefon: +49 221 470 5303 50969 KoelnFax: +49 221 470 5317 --
