After all the discussions regarding MySQL-style clustering (multi-master 
etc), what about a "classic" HA cluster for MySQL? Since the OP 
mentioned high availability, wouldn't the simplest solution be failover 
clustering (ie. single master with failover, shared storage, fenced 
nodes etc) via Centos CS?

As I haven't done this myself I can't really comment further, but does 
anyone else on the list have experience engineering a Centos Cluster 
Suit failover cluster for MySQL?

cheers
