I'm trying to mount an NFS volume with no success. I'm running Linux 7.3 as a VM. I don't see any error messages in /var/log/messages. These are the steps I've taken so far:

showmount 
[root@backup ~]# showmount -e 192.168.1.212

I don't understand why the rpcinfo is missing NFS? Are there any other commands I can try to troubleshoot this?

  • My first thought is firewall. Is it blocking? https://www.howtoforge.com/nfs-server-and-client-on-centos-7 – slm Aug 13 '18 at 01:38
  • That was my first thought as well. However I disable the firewall. – user1854326 Aug 13 '18 at 14:44
  • I setup NFS locally on CentOS 7.x using this guide and it works fine - https://www.howtoforge.com/nfs-server-and-client-on-centos-7 – slm Aug 15 '18 at 02:03
  • This seems possible related - https://unix.stackexchange.com/questions/394781/could-not-mount-netapp-volume-through-nfs-rpcinfo-rpc-timed-out/394825. – slm Aug 15 '18 at 02:03
  • This issue seems to be w/ the NetApp - https://kb.netapp.com/app/answers/answer_view/a_id/1001083. – slm Aug 15 '18 at 02:07
  • In my case, I was using the `v3` flag when my server was on v4. After removing that it worked. – Sridhar Sarnobat Mar 27 '22 at 04:51

The message "Program not registered" indicates a problem on the server, at least I assume that 192.168.1.212 is your server as it is not necessary to add an address to showmount to get information about the local host.

So you should make sure that the NFS server is running on the server. Start with

rpcinfo 192.168.1.212

And if possible verify that the processes are running on the server.

    The server in may case is a NetApp. I've created the volumes, and policies, but I can double check to make sure I didn't miss a step. – user1854326 Aug 13 '18 at 14:46

Make sure the nfs-mountd service is running:

systemctl status nfs-mountd

restart nfs-server service as needed
