GFS, OCFS, and GPFS - Which Filesystem for Oracle?
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?"
Have you looked at a Veritas Cluster? (VCS) The company I work for uses it and we have found it to be very stable.
Um.. perhaps call your Oracle support people. If your company is at all sizable, they probably have support contracts with the companies that provide them their mission-critical software? And their professional services/technical engineering people would surely be the best people to ask.
What about Lustre (http://www.lustre.org)?
BTW, implicitly, closed != bad. Yes, sometimes it does, but not always.
Also, by what definition is a filesystem a "cluster filesystem". One in which the cluster nodes can (a) access, (b) provide or (c) access and provide the filesystem? Not every flavour of clustered filesystem falls in the same category.
I do agree with the license comment on closed source systems - the per-node license fees are ridiculous.
