nfs hangs after nfs server IP change

[Victor Lee]

Hi

we changed IP address of our NFS server. Now my HP-UX 11.0 machine cant see the contents of the server. When we do cd /net/nfsserver and do “pwd” or “ls” it hangs. When I do straight NFS mount of nfsserver:/contents into a directory in / and then try to do ls on that directory, it also hangs.

Here are the steps I’ve taken so far:

1. rebooted the machine
2. applied latest NFS patch
3. created entry for nfsserver in the local /etc/hosts file
4. mounted using the IP address of nfsserver

In spite of the above, problem persists. Any ideas?

thanks
Victor

Hi Victor,

Can you look into the /etc/nsswitch.conf to find out how name resolution is taking place ? Allthough it seems to be a rare hit.

Also is the status normal for other NFS clients. Is it Auto NFS ? Have you changed entry in /etc/auto.direct if you are using that ?

HTH,

nsswitch.conf has "files dns nis" for hosts.

we are using autofs.

there is no entry for this nfsserver in auto.direct.

other nfs clients are working fine.

Hi Victor,

Are you able to resolv the hostname of the NFS server using nslookup command? Also try "traceroute nfs_server_hostname".

Also take some time to assign points to earlier responses to your questions to improve the forum. Here are your questions for which you require to do that
