Following an unsuccessful cluster fallover test， it is determined that the nfsrg1 resource group  was the problem causing the cluster to run the config_too_long evetn. The nfsrg1 resource group contains 10 nfs filesystems that are cross-mounted to the other cluster node.  Without modify8ing the time until warning parameters，what can be done to enhance NFS fallover performance？（）  

• A、 Increase the number of NFS daemons for increased performance.
• B、 Modify the nfsrg1 resource group to use local NFS cross-mounts.
• C、 Create a second resource group to manage half the NFS cross-mounts.
• D、 Create post events to handle the cross-mounts after fallover processing.
