James,

Would like to use nfs version 4.


On the client, mount.nfs and mount.nfs4 are same


client:~ # ls -l /sbin/mount.nfs*
-r-s--x--x 1 root root 232223 Feb  7 07:16 /sbin/mount.nfs
lrwxrwxrwx 1 root root      9 Feb  7 07:16 /sbin/mount.nfs4 -> mount.nfs


client:~ # mount.nfs4 1.2.3.131:/ /mnt -i -o rdma,port=2050
mount.nfs4: an incorrect mount option was specified

client:~ # mount -t nfs4 1.2.3.131:/ /mnt -i -o rdma,port=2050
unknown nfs mount option: rdma
