NFS Failure

[Brian Lee_4]

NFS Server & Client OS: HP-UX 11i

I keep getting the following system message and it causes terminating some of batch jobs from time to time.

Please help me out.
===============================================

Hi,

It looks like the resolving of the server fails sometimes.
Did you try adding the seauxsp1_backup in /etc/hosts ?

Related files.
/etc/resolv.conf
for name server
/etc/nsswitch.conf
for lookup

HTH,

If the server seauxsp1_backup is unreachable on the network or has been booted, or the nfs.server program has failed this error will occur.

Checlist:
Check network connectivity(see earlier post)
ping seauxsp1_backup
ping ip_address of seauxsp1_backup

If the first fails and the second succeeds, its DNS, work on that.

If DNS is unreliable, consider mounting by IP address.

mount -a
# This will work if the nfs mount is in /etc/fstab and the server is up.

Checklist for the server in question

/sbin/init.d/nfs.server stop
/sbin/init.d/nfs.server start

ps -ef nfs

I added seauxsp1_backup in /etc/hosts file of nfs client.
I can ping to seauxsp1_backup with both host name and IP address from NFS client.

None of two system are using DNS.

Both systems have 100FD Manual.

Hi,

You could try restarting the nfs server and core. This will register tghe servers to the rpc daemon. rpcinfo -p on nfs server will list registered services.

HTH,

DO the following

host seauxsp1_backup
host IP_ADDR_OF_THE_ABOVE_HOST

both r the same ??? NFS somehow needs reverselookup working !

Regds,

I restarted both NFS client and server but the problem is still happening.

I would like to approach this problem in the point of resource shortage.

The client has only 400MB buffer becaue SAP are using most of assigned memory.

Also, CPU usage is pretty high.
