RPC timeout errors

RPC timeout errors

[Kevin]

I am running an nfs server and client; bot machines having RedHat 7.1 
installed with kernel 2.4.2-2 and nfs-utils-0.3.1-5.  The server seems fine.  
Everything in my host files are perfect.  Infact, i checked my messages file 
in /var and it shows the server allowing an incoming nfs connection from 
client  192.168.0.1.  

I have the following line in my /etc/fstab:
192.168.0.254:/home/Fear                /mnt/server1          nfs     
rw,hard,intr    0 0

With that added, i used to be able to type mount -a and it would mount 
everything in /etc/fstab.  It tries to mount the nfs, but chokes up & gives 
me the error "mount: RPC: Timed out".  I followed every instruction located 
in the Linux NFS HOWTO and it referred me to this e-mail for questions.

Thanks for your time.

Kevin

=09I've run into this before, and the problem is that the mount daemon is=

to reverse and forward resolve that IP address. If you dumped the client =
and=20
server either in a DNS server or in the /etc/hosts file you should see an=

instanteanous mount.

=09To everyone else: Is there a way of turing this off in the mount daemo=

would like to have my auto-install scripts get to NFS without having to a=

DNS entries first.

=09Hope this helps!

Interesting.
We have ~80 nfs clients and since adding the last 30 we got the problem
that when a lot of users are using the system we often get "RPC: timed
out" on a lot of machines, but in the server lot nothing looks wrong.
Maybe I should try setting up an additional nameserver on the nfs server
because the machine currently running the nameserver is an old sun
ultra1 enterprise...
We also experienced a weird problem where after everything was running
fine for a few days the server would refuse mounts to some clients with
"getfh failed" and you'd have to exportfs -rav to get it working
again...
