    In OCFS2 we call readonly+journal+connected-to-cluster "soft
    readonly". We're a live node, other nodes know we exist, and we can
    flush pending transactions during the rw->ro transition. In addition,
    we can allow a ro->rw transition.
    The no-journal+no-cluster-connection mode we call "hard
    readonly". This is the mode you get when a device itself is readonly,
    because you can't do *anything*.
