I would urgently need a Cluster Filesystem that runs with Oracle Clusterware.
Today, we would recommend the Sun Cluster Advanced Edition for Oracle RAC. This includes QFS which is a distributed file system. See http://www.sun.com/software/cluster/faq.xml#q21
Currently Cluster Filesystems with Solaris need very expensive solutions (like Veritas Storage Foundation or SUN Cluster) that are no longer accepted by the customers (with regard to Linux solutions).
I can't comment on the price, other than to say that it[1] is free (as in $) for research, development, or education purposes. There is also a variety of different pricing options for production systems which require support. Anecdotally, I hear that it often costs less than VSF for production systems. [1] it will depend on what "it" is, what your company or institution does, and where you live. I find the www.sun.com pages on this topic confusing, so I'd recommend contacting your local Sun sales office.
That's why I want tp propose to think about a project to integrate ocfs2 in OpenSolaris.
OCFS2 is an Oracle "project," so you should ask them. Without Oracle's blessing, you'd be wasting your time. http://oss.oracle.com/projects/ocfs2/
ClusterZFS would be surely an interesting next step. But unnecessarily complex for RDBMS purposes that needs a cluster FS only for some archival purposes and shared access for backup and restore (ZFS characteristics like copy on write are not all too good for RDBMS with much scattered I/O, so we would always prefer Cluster Raw Devices over Cluster Files for normal database files)
For raw devices, zfs offers zvols. The jury is still out pondering the merits of databases over ZFS. From a RAS perspective, this combination is excellent. But I don't think we have much real data to address a performance perspective (that is being done by others... who will speak up when they are ready :-) Sun marketing has been collecting requirements for a distributed version of ZFS. Please check this forum's archives and provide input.
