Your output indicates that you did not successfully stop NFS; so you still have locks in place that prevents a restart. Something is preventing the shutdown; maybe files open that the shutdown script can't close. etc.

Peterchu,
As Vernon has mentioned the NFS daemon has not been shutdown properly on the host. I would suggest that you follow the sequence below

1. Try one more time shutdown of NFS like
#./nfs stop

2. Verify if all the nfs daemons are
shutdown by doing
# ps -ef | grep nfs

3. If you see any nfs daemons from item#2,
make sure that you kill them like
#kill -9

4. Now do a nfs start like
#./nfs start

Let me know if you have any questions

regards

Peter,
I think all this is related to another posting.

NFS in a medium-large network is an ugly beast.
If you already knopw all about

fuser
lsof
nscd
autofs
rpc.mountd

then you should have all you need and work with it. No other solutions. With such a problem I'm working with iozone (look at google) and linux nfs-howto.

Peace, R.

put the command

set -x

In the nfs startup scripts in /etc/init.d

Try again, you will at least get some diagnostics.

This is almost always due to inconsistent network setttings in /etc/sysconfig/network-scripts

Give them the old eyeball scan and see what you find.
