Question

mount to NFS server 'voda50' failed: RPC Error: Program not registered

Asked by: LinuxDuke

Hi Experts,

I'm busy mount two directories from a unix sever called voda50 to my Redhat servers but after updating the /etc/fstab file and running the command mount -a I get the folloing error :
[root@fldemtra5 ~]# cat /etc/fstab

Then nothing is mounted any Idea what might be causing this error this is the out put from the /var/log/massages.

You are missing nfsd and mountd entries in /etc/rpc
They should look like this:
mountd 100005
nfs 100003
rquotad 100011
nlockmgr 100021

Probably they are insluded when you install portmapper on local machine.
nmap uses less legal ways, but gets better informed than rpcinfo

Double check whether voda5 is actually sharing.
exportfs -a
Are you able to mount that share on any other system?
Like gheist said, you need to have nfsd, and possible statd running on voda50.

make sure voda50 is setup as an NFS share as well as which version of NFS it handles, V2, v3 or v4.
This way part of the mount directives you would also need to specify which mode NFS you are using. UDP/TCP.

See whether voda5 can mount the NFS share locally.

Does your Redhat system running the /etc/init.d/netfs at boot?
chkconfig --list netfs

You do not need any services on the client running, but portmapper or rpcbind will supply /etc/rpc file so that nfs client side is able to differ between mountd and nfsd.

You certainly must have rpc.portmapper running on the client. A reboot shouldn't be necessary, but might start the portmapper automatically now that there are nfs entries in fstab. Slackware does that but I don't know if Redhat is that smart. For now you should just be able to start it by hand: /etc/rc.d/init.d/portmap up

 

by: duncan_roePosted on 2009-02-04 at 03:15:29ID: 23546758

Looks like the program was called portmapper in Redhat, not rpc.portmapper

voda50 AIX server was not exporting the shares when using mount -a it was not providing the shares. The reason which is a very unusual one on the nfs server side was because the dns entry where not add for server1 in /etc/hosts of voda50 although dns was available it only worked when I add the entry in /etc/hosts. AIX is a funny one. Thanks for all your help
