cluster architecture question

[Arnaud Abélard]

Hello,

I built a mysql cluster using the following schema with mysql 5.0.18:

A is a mysql & data node
B is a mysql & data node
C is a mysql & data node
D is the managment node

E is a virtual IP used for load balancing (with ipvs) on the 3 mysql nodes.

The cluster seems to work fine except for a few things:
1- Since the mysql database doesnt seem to be clusterised, i have to create the databases, tables, users and permissions on each node (A, B and C) before the database is fully available on the cluster, is that the normal behavior of the cluster? Can't i just use a random node (choosen by ipvs) to create the database, that would be replicated on the other nodes?

2- ndbd crashes from times to times

3- i sometime get the following error "Got error 241 'Invalid schema object version' from ndbcluster"
