Actually, Oracle developed OCFS2 (Oracle Cluster File System 2) just for
this purpose, and it is included in the upstream Linux kernel.  The main
problem with it is that it is not a general-purpose filesystem.  It has
strange semantics about file locking, and is optimized only for Oracle
IO patterns.

So, in theory it should be possible, but I don't know if anyone has
tested it.
