NFS tcp not available, falling back to UDP; RPC failure


I have installed Suse Linux Enterprise Server 10 sp1 on our machines, and on the latest few I keep noticing as the machine boots up I get the following errors:
- nfs related, says tcp unavailable falling back to udp, and it gives a warning that errors may result,
- also right after the nfs tcp error, it mentions RPc failure, or RPC port mapper failure.

what does this mean, and how do i fix it.

please try

Code:
/usr/sbin/rpcinfo -p localhost | grep nfs
if no output then NFS is not registered with Portmapper

then try

#service nfs start

hopefully it may help

managed to get a copy of the exact error on bootup:

Importing Net File System (NFS)mount server reported tcp not available, falling back to udp
mount:RPC:Remote system error - No route to host
--------------------

I did rpcinfo -p and get the following:

program vers proto port

100000 2 udp 111 portmapper
100024 1 udp 32772 status

network service should start first and then nfs also see if portmap and rpc services are running.

Hi


The another thing what I know is NFS is protected by SElinux, if possible, Can you please try to disable it for time being.
