Re: Help in setting up a cluster

If you want to create a cluster that use multiple servers, you can for
your two different projects :

1 - (converting song) - use a scheduler such as torque / slurm-llnl
(debian package name) / sun grid engine (the name might have change)
and use those to distribute the different jobs across the different
nodes. You might need to have a way to authenticate user across all
the node + a filesystem such as NFS to share the files.

2 - (load balancer/high availability) - you might need to consider
different solutions that will be able to fail over such as
heartbeat/pacemaker or corosync/pacemaker, if you want to do load
balancer you might need to look at haproxy or some other high
availability solutions.
