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

If you have encountered issues like

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


mount.nfs4: Protocol not supported

To resolve this

Mount with NFS version 3 (with 4 verbose flags)

% mount -vvvv -t nfs -o vers=3 nfs-server:/share /mnt/nfs


  1. Error “mount.nfs: requested NFS version or transport protocol is not supported” when attempting to mount an NFS share on Red Hat Enterprise Linux 6

1. Assuming this is your mount command

mount -t nfs -o vers=3 XXX.XXX.XXX.XXX:/myserver/nfs /myclient/nfs


2. And if you are using showmount command from an NFS client and the following are observed

3. You have to access the NetApp Storage to check the NFS Protocol is enabled. I’m using the Netapp OnCommand System Manager

4. Check that the NFS Client can mount.

showmount --no-headers -e nfs_server
/ (everyone)


  1. showmount fails with clnt_create: RPC: Program not registered when executed from a RHEL6 NFS client communicating with a NetApp filer
