remote mounting

chad_c — Mon, 27 Nov 2006 18:07:31 GMT

Hi. I would like to manually remote mount the following file system.

/arc/sys_backups/txnnm3

Note: I am mounting from one HPUX11.11 server to another HPUX11.11 server

How can i do this?

Regards,
Chad

Hi Chad,

You can do this using NFS, for more details you can see NFS and exports manual

How to enable it is:
On the file server:
1. # /sbin/init.d/nfs.core start
2. # /sbin/init.d/nfs.server start
3. Put these lines on /etc/exports

/arc/sys_backups/txnm3 -rw,anon=2,access=

4. # exportfs -av

On the client:
1. # /sbin/init.d/nfs.core start
2. # /sbin/init.d/nfs.client start
3. # mount :/arc/sys_backups/txnm3

Regards,
Sandy

Hi Sandy,

Thanks for the response. I walked through the above, which makes sense. Then retried.

For some reason, I'm still getting the following:

nfs mount: get_fh: txovo:: RPC: Rpcbind failure - RPC: Timed out

We used to be able to do this. Does anyone know if installing ssh or sftp would cause this time out to occur? That is the only thing that has changed since we were last able to do this.

Regards,
Chad

Hi Chad,

Let's back up a little and try something simple. From the NFS client system can you issue the following commands:

# rpcinfo -p
# showmount -e

and post the results of those two commands?

Thanks,

Dave

Dave,

Results are as follows:

rinnm5# rpcinfo -p txovo
rpcinfo: can't contact portmapper: RPC: Rpcbind failure - RPC: Failed (unspecif)
rinnm5# showmount -e txovo
showmount: txovo: RPC: Rpcbind failure - RPC: Timed out
rinnm5#

Is the portmapper/rpcbind running on the NFS server? If you log into txovo and issue the same commands:

# rpcinfo -p txovo
# showmount -e txovo

What do you get? Does a ps listing show rpcbind or portmap running?

Dave

Hi,

there may be a name resolution problem between the hosts rinnm5 and txovo.

Did you try a ping/telnet/ssh between these servers?

Try vice verse
nslookup rinnm5
nslookup txovo

Else try with FQN -
nslookup rinnm5.
nslookup txovo.

Hi Chad,

From rinnm5, see if you can get rpcinfo for a different server. This should tell you if the problem is with rinnm5's RPC interface. What does '/etc/netconfig' look like?

chad_c — Tue, 28 Nov 2006 14:02:13 GMT

spex,

Yes. I can rpcinfo -p all other servers except txovo server.

chad

Re: remote mounting

Dave Olker — Tue, 28 Nov 2006 14:56:21 GMT

One other thing to try would be to collect a network trace of the rpcinfo from the client to a working server and then an rpcinfo from the client to the failing server and then compare the two commands in the network trace to see if you can see any differences between the responses from the working and failing server.

If you want to collect a nettl trace of an rpcinfo -p command from the client to the working and failing servers I'd be happy to look at it. I'd just need the IP addresses of the failing and working servers so that I could filter the trace to isolate those respective packets.

Regards,

Dave

Check if these processes are running...

#ps -ef| grep rpcd
#ps -ef | grep portmap ( in HP-UX 10.20 )
#ps -ef | grep rpcbind ( in HP-UX 11.X )
#ps -ef | grep nfsd

If some of these processes are absent you will have a problem with remote mount.
Geetha.
