Firebird SQL Clustering questions

Here comes the fire cluster question
I want to build an Load Balanced Active/Passive Firebird SQL Cluster
(two Active/Passive clusters which have access to the same data). So
the set up will be as follows:
1. Two Redhat GFS Clusters
2. One shared storage of 1TB
3. Layer7 Switch

So my idea is to implement GFS on the shared storage (/shared/db) and
then create two quorums one for one cluster, and the other for the
second cluster. After that I would register the following into a
cluster service:
- Shared IP address
- Shared Storage
- Firebird init.d script

So have anyone managed to create such scenario or is this kind of
scenario supported on Firebird 2.0.1 Classic.
