    I'm not familiar with RAW/Oracle RAC, but the downside of GPFS is that
    it's not really a high availability file system. There's only one
    heartbeat path (if your network goes down/has to be taken down you'll
    loose connection to the file system), and when you need to upgrade
    GPFS you often have to unmount it on all nodes before doing the
    upgrade, even for minor releases.

    It's still a great file system for other uses though.
