Soma,

May I know why your nfsd is only 4, the default value nfsd 11.23 should be 16.

you may consider increase this value

Hi Soma,

Just start and stop the nfs daemons and its would work fine.

/etc/rc2.config.d/nfs.server stop
/etc/rc2.config.d/nfs.client stop
/etc/rc2.config.d/nfs.core stop

/etc/rc2.config.d/nfs.core stop
/etc/rc2.config.d/nfs.server stop
/etc/rc2.config.d/nfs.client start

Hope it will work !!

Thanks for you feed back.

I have tried before to increase this number but no succeed.Beside i have another hp servers on other subnet with same value of 4 and are mounting normal.

I think the problem is some where else.even i opend all ports on the firewall between the two servers but with no success.

points are assigned but the problem is still the same.

Soma,

You are saying the other server working, is the NFS cumulative patch same ?

Can you please check if you have installed

PHNE_36257 11.23 NFS cumulative patch

WK
please assign points

soma_3 — Mon, 03 Sep 2007 02:40:54 GMT

None of my servers the ok ones nor the problemed one has the patch you mentioned.
PHNE_36257 11.23 NFS cumulative patch
But:-
PHNE_33982 1.0 NFS cumulative patch
PHNE_33102 1.0 RPC commands and daemons cumulative patch
the above patchs are on the ok servers.

But with the problemedd one the followings are installed.

PHNE_32055 1.0 NFS cumulative patch
PHNE_32056 1.0 RPC commands and daemons cumulative patch

Hi soma,

try to specifiy the nfs version
example:-
#mount -o bg,vers=3 gator:/tmp/hp /nfsmount

soma_3 — Mon, 03 Sep 2007 04:04:07 GMT

Hi,
mount -o bg,vers=3 thuraya0:/opt /LATIF
The result is:
nfs mount: get_fh: thuraya0:: RPC: Timed out
nfs mount: retry: retrying(1) for: /LATIF after 5 seconds
nfs mount: retry: giving up on: /LATIF

Hi,

Are you certain you have the firewall configured properly to allow inbound and outbound access to all the RPC programs used by NFS? The client would need to successfully communicate with:

Daemon Port
------------------ ------------
rpcbind 111
nfsd 2049
rpc.mountd variable
rpc.lockd variable
rpc.statd variable

Proper configuration of the firewall between these boxes is critical for NFS communication between client and server. Some of the configuration is easy - ports 111 and 2049 are always used for rpcbind and nfsd. The other daemons can be tricky to configure because they start on different ports each time.

HP recently introduced a patch that allows you to assign static port numbers to rpc.mountd, rpc.statd and rpc.lockd. The original patch with this enhancement was PHNE_34550 but it has since been replaced by PHNE_36257. After installing one of these patches, you can direct rpc.lockd/statd/mountd to use static port numbers by modifying the LOCKD_PORT, STATD_PORT and MOUNTD_PORT entries of the /etc/rc.config.d/nfsconf file.

Once you are certain that the NFS client is able to successfully communicate with all these RPC daemons on the NFS server the mount should work (assuming everything else is configured properly).

Regards,

Dave
