Clnt_create: RPC: Program not registered ( NFS issue)

Recently I was cofigurating on NFS server for my college, I got the following error when I try to mount the share. [root@backup ~]# mount -t nfs 10.0.5.25:/NFS/Redhat5 test/ mount: mount to NFS server ’10.0.5.25′ failed: RPC Error: Program not registered. [root@backup ~]# On the server I run the following command to the check the service status… [root@proxy NFS]# showmount -e 10.0.5.25 clnt_create: RPC: Program not registered [root@proxy NFS]# Fix  Just restart the nfs service using the following command it will fix the issue. Before we were using portmap and nfs services for NFS server, now its changed to rpcbind instead of portmap. so restart rpcbind first then nfs second..this is the way how it works.. [root@proxy NFS]# /etc/init.d/nfs restart [root@proxy NFS]# showmount -e 10.0.5.25 Export list for 10.0.5.25: /NFS/Redhat5 10.0.9.223 [root@proxy NFS]#
