HA cluster

[Jordi Prats]

Hi all,
This is my first post on this list. I'm currently studding to change a 
HA Linux cluster to a HA FreeBSD cluster.

Currently I have two (redundant) load balancers with LVS, and several 
NFS, MySQL and PostgreSQL servers using RedHat cluster suite.

What would you recommend to change this Linux setup to a FreeBSD setup? 
Any experiences with HA clusters with FreeBSD?

Thank you!
Jordi
