NFS server not responding still trying...

[Jonathan Caplette_1]

Hi guys,

I have a new HP-UX 11i box and I try to mount NFS drives on that machine and I got that with a lot of my drive:

NFS server not responding still trying...

The NFS servers are working good, I can mount the same filesystems on other HP-UX 10.20, 11 and even 11i box... is there patch or something else that I'm missing here???

Thanks
Jonathan

Hi,

Can your new 11i box correctly resolve the hostname and IP address of the NFS server?

Do you need to add an entry in /etc/exports on the NFS server for the new 11i box?

Hello!

Do you have connection problems between this
two machines?
Check if the server made export for the new machine.

make sure the hostname of the new 11.i box is in the /etc/exports file of the NFS server.

also run /usr/sbin/exportfs -a on the NFS server

Them try to mount.

Ok guys.. Sorry for the inconvinient ... I found out that it was because when my DNS server went down, he took with him the nfs server too.. So I had to restart the nfs daemon on the machine.. every thing work fine now...

Thanks Again!

A common cause of this problem are inconsistent network settings.

on the host/server

lanadmin -x 0

replace 0 with the actual number of the card

You should see 100 BaseT Full Duplex

Or whatever full speed is.

Check this on both server and client.

Next step is to make sure any switches have the ports configured as expected.

HP NIC's prefer manual explicit settings and have trouble with how Cisco switches do auto negotiate.

Have the Cisco admin switch to explicit, boot both boxes

re-run the lanadmin commands, if there is conflict you may be forced to hard code your setttings in one of the following files, depending on the NIC card you have.

/etc/rc.config.d/hpbtlanconf
/etc/rc.config.d/hgsclanconf

As you have seen, DNS is a critical service and can affect every machine and service on the network. You may want to add a regular monitoring jib in cron to make sure the server is really running. Start with a ping test and then use nsquery to see if the server is responding.

Hi,
i suugest you to put the direct and reverse lookup in the /etc/hosts, for the NFS shares in general.

I hate when NFS goes down... it's fragile by its own...

Heres a good manual for your reference, it will help you out with future NFS issues if they arise.
