I am trying to configure NFSv4 only server in CentOS 6.10

I've disabled NFS v2 and v3 using this conf file /etc/sysconfig/nfs

MOUNTD_NFS_V2="no"

MOUNTD_NFS_V3="no"

RPCNFSDARGS="-N 2 -N 3"

I followed this link for reference.

As per this document NFSv4 doesn't need rpcbind anymore.

But if I start nfs service without starting rpcbind service I am getting below error. NFS service is not starting.

[root@server ~]# service rpcbind status

rpcbind is stopped

[root@server ~]# service nfs restart

If I start rpcbind then nfs service is starting properly.

[root@server ~]# service rpcbind restart

How to start nfsv4 without rpcbind ? Is it possible ?

NFSv4 still need rpcbind ?

My kernel version is 2.6.32-754.6.3.el6.x86_64
