nfs not responding

[Rajib_1]

Sir,

I have a problem related to nfs.I have a snfs server named hpsr5.now the problem is all my clients are not able to connect to the server.My checklist is as below.

1)checked network connection by ping command from both ends(by ip and by name)

2)stopped and started nfs.server and nfs.client on both sides.

3)tried manually mounting the server directories on client side

4)restarted both server and client.

Pls respond quickly

regards

Mangesh

Can you NFS-mount your exported directories on the NFS-server itself ?
This would rule out eventual network problems.
Check /etc/xtab : what's in there. Do you see all exported filesystems and servers you expect ?
Do you get an error message ?

Hi Rajib,

Check all the NFS daemon Processes running on the server.
run rpcinfo -p
Check for portmapper daemon.

Ganesh

run this on your nfs server:

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

the results from the showmount should be all the directories available for export. Also check the /etc/exports file to see if anything got changed there.
