NFS Server not responding

[Jody Bennett]

I am getting this message from multiple servers that have nfs mounted filesystems from the same server. They do not all get the error at the same time and it may be several days or weeks before they get the message again. The problem corrects its self after a few minutes. Any hints on what to look for.

Attached is a doc on diagnosing NFS performance. See if it can help.

This is typical and normal behavior for NFS clients. More than likely this server was rebooted or lost its network connection for a few minutes. As soon as the server was back up, the clients resumed normal operation. IT is also possible, that someone stopped the NFS server daemons on this box for a few minutes.

The next time this happens, immediately check the status of this server. See if you can ping it.

run this:

UNIX95= ps -efH|head -1; UNIX95= ps -efH|egrep "inetd|rpc|mount|nfs"|grep -v grep; rpcinfo -p|egrep "service|nfs"; showmount -e; mount -p


and then check /etc/exports to see if it is setup as you expect.

Hi,

To trace out the issue, you can try these things:

1) Ping the NFS server at the time when this message comes.
2) Check whether the nfs daemons are working on the server and clients.
3) Check for network traffic at all times.
4) Check for any program/process which request for any unavailable NFS servers.

Hi,

Again, make sure that all of your NFS servers and clients are having the latest patches applied ! Check for the latest patch bundle in the HP support site.
