The difference mounting the client read-only or not is only a semantic one if no applications on that node do any writing. Mounting it read-only does reduce the risk that some spurious application/user will do writes on the OSS client. We are not aware of any deadlocks when clients are not writing data to the filesystem, but we also don't test this configuration very much.
