mount.nfs: requested NFS version or transport protocol is not supported

Question

NFS Mount is not working in my RHEL 7 AWS instance.

When I do a

mount -o nfsvers=3 10.10.11.10:/ndvp2 /root/mountme2/

I get the error:

mount.nfs: requested NFS version or transport protocol is not supported

Can anyone point me where I am wrong? Thanks.

Solution 1

Check the nfs service is started or reboot the nfs service.

Solution 2

sudo systemctl status nfs-kernel-server In my case this package was not running and the issue was in /etc/exports file where i was having same IP address for two machines. So i commented one ip address for the machine and restarted nf-kernel-server using sudo systemctl restart nfs-kernel-server and reload the machine. It worked.

Solution 3

A precision which might be useful for the dump (like me): systemctl status nfs-server.service and systemctl start nfs-server.service must be executed on the server!
