In fact you have 6 nodes. Why not make it a simple three node cluster
and use the remaining 3 nodes for a test system?

If want to stick to a tiered system, you might add NFS to the data base
layer, so the web servers are real load-balanced boxes with no need for
any HA clustering.

However, it does not really change the need for fencing. As said, check
for SBD.
