You will still be limited to a single primary server with DRBD.
Here is a line from their site:
DRBD's primary-primary mode with a shared disk file system (GFS, OCFS2).
These systems are very sensitive to failures of the replication network.
Currently we cannot generally recommend this for production use.

100% uptime for your e-commerce site! Stay fully operational
even with a db server failure.  Ask me about the GRed database.

We tried Sequioa:
http://www.continuent.com/community/lab-projects/sequoia
 
We wanted automatic failover and geographical distribution
of the database nodes.  Sequoia only supports master-master
operation if the database nodes are on the same subnet.
 
We did not find anything else out there, so we wrote our
own geographically distributed database system.
We can adapt that to your project if you are interested.

Your e-commerce site can be geographically redundant and available
even if failure occurs. Ask me about the GRed database system.

CentOS has the redhat piranha packages available for install.  Piranha
is a repackaging of the linux virtual server software, along with a
web-based front-end.  You can find information about that in the
CentOS docs and also by googling for "redhat piranha".
