Debian installation on cluster
I have an old cluster [30 nodes, specs on each node[2GHz processor, 512MB RAM[[. The nodes have Debian 2.0 installed and I want to upgrade all nodes to Debian 5.0 stable version.
Is there a painless way to do it other than taking each node out, attaching it to a monitor to it and installing by DVD ?
The cluster is used mainly for computation purposes, so we don't need any desktop packages on it, only development libraries and programming languages.
Can anybody point me in a helpful direction to proceed.
Thanks a lot.
