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.

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.

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".
