HPUX NFS problems with Solaris ZFS/NFS server

[Pnaidu]

Hi,
We have NFS write failures whenever HPUX 11.23 client is writing on to NFS filesystem.

NFS filesystem is exported from a SUN ZFS NFS server and is working fine on HPUX 11.11/11.31 (NFS v3)Client.
As a work-around we have set NFS v2 on HPUX 11.23 machines.

Does any one know if there are HPUX 11.23 patche/fix for this?

Thanks,
P.Naidu

Thanks Robert-Jan,
As observed NFSv3 works fine on 11.11 systems but not on 11.23. I'm looking if HP has got fix for this issue for 11.23 systems.

Dave Olker would be the man. You could try sending him an email.

Hi P. Naidu,

Can you provide more details about the failures you're seeing? What is the exact error message. Can you reproduce the error at will? If so, what steps do you use to reproduce the problem?

Regards,

Dave

Hi Dave,

Problem is pretty similar like : http://bugs.opensolaris.org/bugdatabase/view_bug.do?bug_id=6538387

We're running `ar` over NFS filesystem to make an archive of .o files. This command runs fine on local filesystems like on /tmp but with NFSv3 it hangs forever. Even If you open a vi session and try to save the wriiten data over NFS it hangs.

There is no error message reported on syslog.log or on stdout.

Problem can be reproduced whenever you're using Automount NFSv3.
If I mount an NFS dir with ver 2 it works fine.


Thanks a lot,
Naidu

Hi Naidu,

Can you reproduce the problem and collect a network trace of the failure? I'd like to see what kind of error are being returned at the NFS layer, even if they're not being bubbled-up to the application.

Let me know if a trace is possible.

Regards,

Dave
