Not able to mount the NFS drive - Help

[Jasper_15]

Hi,
I have this NFS mount-point hosted by my OpenVMS server and now I can't seem to mount from my Linux server. Here is the error message, " mount /backup
mount: RPC: Unable to receive; errno = Connection refused "

I checked the credentials for both environments and they appear to be correct. I don;t know when it was dismount until I check it today. This setup has been working for the last 2 years and not sure why it stopped working now. Anyone has any ideas on how I can fix this??

Thank you in advance.

does linuc nfs client allowed to mount that NFS share?? check it.

Are you able to ping / nslookup to NFS server? Connection refused is saying that "NFS Server daemon may not be running on NFS Server machine" also.

Are you able to mount NFS Server's FS with some other machine? Post reponse for this.

hth.

Yes, I can ping the host and all. I even have the other server in my /etc/hosts file as well. I can even do ftp to the other server without any issues. I am confused. Do you think it might be a service that currently not running on my OpenVMS server? if so, what would that be?

From the client run:

rpcinfo -p ip_of_nfs_server
showmount -e ip_of_nfs_server

Verify that the name resolution is working correctly, check DNS and hosts files.

On the server, verify that the nfs and portmap services are running.

Here are the results from the Linux server;

rpcinfo -p 171.168.1.11
program vers proto port
100000 2 tcp 111 portmapper
100000 2 udp 111 portmapper
100003 2 tcp 2049 nfs
100003 2 udp 2049 nfs
100003 3 tcp 2049 nfs
100003 3 udp 2049 nfs

showmount -e 172.168.1.11
rpc mount export: RPC: Unable to receive; errno = Connection refused

Where else can I do?

Many thanks!!

I think that you should restart nfs services, I don't see the mountd running in the output of rpcinfo.

i think there is some problem with the port
