Documentation?!...  well... there's not much.

It depends on what you're trying to achieve with your cluster.  If you
want a simple active/passive failover cluster, I'd suggest
heartbeat/pacemaker for clusterizing the services coupled with drbd
for replicating files.  I recently set up a cluster like this that's
now in production.  This particular system connects to the PSTN via
PRIs, and a specialized piece of hardware detects which system is the
active node and physically routes the PRIs to that node.

I should probably write something up and post it somewhere, but time
is always an issue.  If you need specific help with this kind of
setup, though, feel free to ask, and I may be able to assist.

If you want an active/active setup, I think you'll have to look into
using dundi.
