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 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 tcp 111 portmapper 100000 2 udp 111 portmapper 100024 1 udp 32772 status 100021 1 udp 32772 nlockmgr 100021 3 udp 32772 nlockmgr 100021 4 udp 32772 nlockmgr 100024 1 tcp 38120 status 100021 1 tcp 38120 nlockmgr 100021 3 tcp 38120 nlockmgr 100021 4 tcp 38120 nlockmgr 100003 2 udp 2049 nfs 100003 3 udp 2049 nfs 100003 2 tcp 2049 nfs 100003 3 tcp 2049 nfs 100005 1 udp 863 mountd 100005 1 tcp 864 mountd 100005 2 udp 863 mountd 100005 2 tcp 864 mountd 100005 3 udp 863 mountd 100005 3 tcp 864 mountd |
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. |
