Hi All

Iam facing problems in NFS

Here we have nearly 10 nfs servers and the filesystem is exported
Sometimes due to network problem nfs filesystem hangs
If I stop /sbin/init.d/nfs.clinet and
ctl-amd ...and restart it again
Nfs will stilll hangs .Only option is to reboot the server

Is there any way I can solve this issue

Thanks
Binu

OPTION 1: PATCH your systems!!!!!!!!!!!!!!

OPTION 2: REDUCE the network outages!!!!!!

OPTION 3: USE samba or CIFS/9000
samba: http://hpux.ee.ualberta.ca/hppd/hpux/Networking/Misc/samba-3.0.11/
CIFS/9000: http://www.software.hp.com/portal/swdepot/displayProductInfo.do?productNumber=B8725AA
http://www.software.hp.com/portal/swdepot/displayProductInfo.do?productNumber=B8724AA
http://www.software.hp.com/portal/swdepot/displayProductInfo.do?productNumber=CIFSTP3

OPTION 4: ALL OF THE ABOVE

I'd go with option 4!!

You didn't mention what version of HP-UX you're running, but I can tell you that reasonably well patched 11i NFS servers do not have anywhere near the problems that we use to experience back on 11.0 and especially before then.

If you are having NFS issues with 11.11, it probably means you don't have the latest patch bundle installed: http://www2.itrc.hp.com/service/patch/releasePage.do?BC=patch.breadcrumb.main|patch.breadcrumb.bundle|patch.breadcrumb.releaseIndexPage|&releaseId=5013-3299

of course option 2 and option 3 are still viable.

You can choose on the mounting machine:
- use 'intr', allow interrupts so the nfs-action can be interrupted if the server does not respond.
- use 'soft', to have a time-out if the server does not respond.

If you have a bad network connection and the server is most times up and running, best to use 'intr'.

If you have a server that is not alwais available, best to use 'soft'.

`sam` gives many options to tune nfs-mounts. Other systems do provide most of them.
