unable to mount NFS share

807557
    Hello All ,

    I am unable to mount the nfs share from client. I am getting the below error messages.


    # mount -F nfsserver:/sapmnt /tmp/test
    nfs mount: nfsserver: : RPC: Rpcbind failure - RPC: Timed out
    nfs mount: retrying: /tmp/test
    nfs mount: nfsserver: : RPC: Rpcbind failure - RPC: Timed out
    nfs mount: nfsserver: : RPC: Rpcbind failure - RPC: Timed out
    nfs mount: nfsserver: : RPC: Rpcbind failure - RPC: Timed out
    nfs mount: nfsserver: : RPC: Rpcbind failure - RPC: Timed out


    I am able to mount the share from client using physical hostname, i am unable to mount share using the VIP configured in nfs server.


    I am able to ping/tracroute the servername from client.


    Could you please help me on this.



    Regards,
    Rajesh.

              Is it an IP resolution issue? What happens if you run...

              showmount -e <IP Address of NFSSERVER>

              Are the server and client on the same subnet? What's in between the two machines?

                Please find the showmount output with IP address of nfs server

                # showmount -e <IP address>
                showmount: <IP address>: RPC: Rpcbind failure - RPC: Timed out
                #


                It was worked 2 weeks back, suddenly stops working.

                we able to ping/traceroute the server from client

                the rpcbind port is reachable from client

                  Hi Rajesh,

                  Rpc bind failure means.....
                  Client is unable to communicate with server through rpc.

                  RPC is the communication mechanisam that lay comm. b/w server and client.

                  Check from server, whether nfsd and mountd are registered by rpc or not by using
                  rpcinfo -p.

                  If not, stop and start the nfs services on both sides.

                    check the moutd UDP port on firewall. Firewall might be blocking the UDP port for mountd.
