HI,
We are a small biz that wants to start implementing clustering of our
services, but not sure if LVS is necessary just yet. We are starting with
just two boxes with both HTTPD/SquirrelMail and MTA/IMAP on both boxes with
NFS-based backend on a 3rd machine. We'll put all mail spools and SM data
dirs and PHP sessions (file-based) on the NFS machine.
Our question is if there will be any problems to consider starting out with
a DNS round-robin load balancing instead of more complex LVS stuff?

yes, LVS finds out if there are problems with apache and takes the
server with problems out of production.
