NFS server on is not running. Login into that machine check syslog.log or dmesg related informations.

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

# /sbin/init.d/nfs.core stop
# /sbin/init.d/nfs.core start

will help to restart NFS server.

Hello,

This is due to NFS server is not reachable or not responding. You need to restart NFS server by,

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

# /sbin/init.d/nfs.core stop
# /sbin/init.d/nfs.core start

You may have network issues?? Is server available all the time?? A continuous ping to server may give some information.
From client, check
ping
nslookup (on ip and on host name)

Hi Chan,
A simpe idea, but looks funny. If is not a production machine, and you can reboot the machine. Then please reboot the machine.

This have helped me many times, when I faced the same problem. This also saves your time for
debugging without reboot.


note:
You can assign zero points, if this is a stupid answer,but I guess this will definetly help you.

I mean to say, give init 6 on the NFS client machine.

Prabhu,

What is the needed to reboot the NFS client when the problem is with NFS Server?

Bond,

May be you can restart NFS client in client side as,

# /sbin/init.d/nfs.client stop
# /sbin/init.d/nfs.client start

Hi Bond,

Apart from this pls check the speed of LAN card on both NFS server and NFS client have 100Full Duplex and check if the cable/switch in capable of this.

Also look for the valus NUM_NFSD into /etc/rc.config.d/nfsconf

may be it that needs to be increased.
