NFS - RPC: Program not registered -- Linux

[Debbie Fleith]

Although I see some other threads related to this problem under HP-UX, I've yet to find help on this error under Red Hat Linux 3. My NFS server is Red Hat Linux 5.

I am unable to mount a drive from the client without this error. I was able to mount one of them a few days ago, and now its not accessible.

Any ideas that assist me will be rewarded with proper points.

Ensure that the portmap service is running. Ensure that the NFS programs are registered with rpcinfo -p. Ensure that security enhanced linux is disabled and your firewall is also disabled.

Server side was OK. On client side Portmap was running, rpcinfo -p showed processes, but ipchains was enabled. I disabled it, and still didn't help. I decided to reboot and I received these errors:

Jan 28 13:50:11 dentahiti mount: mount: RPC: Program not registered
Jan 28 13:50:11 dentahiti last message repeated 4 times
Jan 28 13:50:11 dentahiti netfs: Mounting NFS filesystems: failed
Jan 28 13:50:11 dentahiti netfs: Mounting other filesystems: succeeded
Jan 28 13:50:11 dentahiti autofs: automount startup succeeded

Do these boot errors indicate anything obvious?

[Ivan Ferreira]

Maybe, the required services are not started yet when the client tries to mount the file system. Try running:

mount -a -t nfs

Or

mount /mount_point

After the system is up. I had a similar problem and the solution was to modify the services startup order.

[Debbie Fleith]

No luck.

#mount -a -t nfs
mount: RPC: Program not registered
mount: RPC: Program not registered
mount: RPC: Program not registered
mount: RPC: Program not registered
mount: RPC: Program not registered

#mount /mnt/u
mount: RPC: Program not registered

Hi Debbie,

From the NFS client, issue the following command and post the output:

# rpcinfo -p
# showmount -e

From the NFS server, issue the following command and post the output:

# rpcinfo -p

Although I had all server-side components running when I was able to mount a few days ago, all of this feedback helped me determine that a reboot occurred and nfs services were stopped on the server-side.

I have things up and running again now and have made changes to have nfs startup always now.

Thank-you.

NFS on server side had stopped running.
