amani asks: "My company has a Oracle 9i RAC database running on a Sun cluster. In 6 months we are looking to replace the cluster with either a Linux or an AIX solution that will involve SAN storage. I see that their are a variety of filesystems for Oracle and Linux. Sistina (Red Hat) has the GFS, Oracle has the OCFS, and IBM has GPFS. Does anyone know the pros and cons of each of these filesystems ,and which one would be better for a continuously growing database?"
