I don't know if metalink note 413098.1 (Extremely Poor RMAN Backup Performance to NFS After Upgrade to 10.2) still applies in 11gR2, but it's something to consider. Even if the backups were on a non-clustered file system LUN that was mounted to one node, if you lost that node, it should be pretty easy to swing that disk to the surviving node.
