Hello,

There may be some problem with the NFs server "db1". Do you have shares from "db1" connected to your rp7400 ? Better option is keeping find to local serverby adding -local

It is problem with NFS shares from db1 server. Try to search local files only if you don't want to get any error or unmount file systems.

To search local file systems then,

# find / -local -name sp*.ora -print
# bdf -l

will help you out.

Yes, you can stop/start the NFS server "db1". Or it could be some network issues, Just check you are able to ping to "db1"

You can stop and start NFS servers by,

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

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

If you are logged in db1 machine then,

# /sbin/init.d/nfs.client stop (If required)
# /sbin/init.d/nfs.client start

# /sbin/init.d/nfs.core stop (Must)
# /sbin/init.d/nfs.core start

# /sbin/init.d/nfs.server stop (must)
# /sbin/init.d/nfs.server start

Now try to check syslog and showmount command output for nfs status.

yes. IT will solve the problem. Nfs server is not running there.

Re: find issue

see man page of nfs(7).

--- man 7 nfs ---

If the server is down or inaccessible, the client receives the message:

NFS: file server not responding: still trying.

The client continues resending the request until it receives an acknowledgement from the server. Therefore, the server can crash or power down, and come back up without any special action required by
the client. The client process requesting the I/O will block, but
remains sensitive to signals (unless mounted with the nointr option)
until the server recovers. However, if mounted with the soft option,
the client process returns an error instead of waiting indefinitely.

Answer: Restart nfs.server and nfs.core available in /sbin/init.d/ directoy.

Hi Wish, Make sure you are able to reach "db1" by pinging it. If you are able to ping to "db1" , then its a problem with NFS server. Restarting NFS server will solve your problem.

Another cause of this problem is bcas of heavy load in nfs server access. What is the configuration you are using in /etc/rc.config.d/nfsconf file?

grep -Ev '^$|^#' /etc/rc.config.d/nfsconf

post this.

Hi Wish, How many NFSD can be run from your server ? Check with /etc/rc.config.d/nfsconf
and post your information.

-Arun

Re: find issue

Muthukumar_5 — Mon, 02 Jan 2006 03:55:58 GMT

Remove the /etc/exporfs file for the content of /maharaja/praxisdmp.

Do this steps,

# /sbin/init.d/nfs.client stop
# /sbin/init.d/nfs.core stop
# /sbin/init.d/nfs.server stop

# /sbin/init.d/nfs.core start
# /sbin/init.d/nfs.server start
# /sbin/init.d/nfs.client start

Do this steps. Post these:

a) /etc/rc.config.d/netconf file contents.
b) mount
c) exportfs -v
d) showmount

after doing above steps.

Is nfsd running in console?

# ps -ef | grep nfs

What are you getting for this:

# grep -Ev '^$|^#' /etc/rc.config.d/nfsconf
# showmount -ede

Are you still getting same errors?

Which file system you are trying to mount in remote NFS clinet?

Hello,

Post the content of /etc/rc.config.d/nfsconf
You have posted netconfig, which is not required per se.

Re: find issue

Muthukumar_5 — Mon, 02 Jan 2006 05:07:32 GMT

I hope bdf / ls -l is getting hung on NFS client right?

Try to restart nfs.client in client side.

Remove the mount which mounted from db1 server as,

# umount

I hope bdf and ls -l is working on server side.
