Marc, 

Simple, create a MySQL cluster using two servers.  I would recommend
using Linux HA with DRBD for the database.  This is simple enough to
configure.

Then point all of your servers to that cluster.  We have 4 SA daemon
servers pointed to one of these clusters.  Unless you don't configure
the cluster correctly you shouldn't have any real downtime.  It takes 15
seconds max to fail over (that's pulling the plug on the main node).

Why replicate...  WE tried that with limited success.  Do it right from
the beginning.

Subject: MySQL on multiple servers

OK - here's what I want to do. I'd like to have more than one server 
that is all feeding into the same database. And I want the databases set

up in a way that if the main server goes dow that the other servers run 
locally. I don't need every update to have to make it to every database 
in the event of any downtime. I just need it to work great when 
everything is up and pretty good when some servers are not running.

So - what are the MySQL options that people are using with multiple
servers?

What I'm thinking I'd like to do is have all the spam filter servers run

off of a main server and that server replicate to the satalite servers 
and that if the main server goes down then the other servers run on 
their own. I also would accept once a day copying the mysql database 
from the main server to the other servers at night so if the main server

went down the other servers could run off of day old data.

How does everyone else deal with this?
