NFS write failed / RPC error

[David Piller]

Hi,

i just wanted to do some test compile on a machine which was installed a few days ago, and received the following message:

NFS write failed for server aclx06: error 11 (RPC: Server can't decode arguments)

Do somebody know what the purpose can be?
I also tried to find an RPC error list but was not sussesful. Any description, guideline would be a great help.

Thank you.

Hi,

welcome to this forum!

I'm missing important information considering your question:
- OS-Version of NFS-client and NFS-Server
- rpcinfo -p client
rpcinfo -p server
- on client: fgrep nfs /etc/mnttab
- in which way was the mount done (command)? Is automount used (map?)?
- firewall between client and server?

Hi,

just received this reply from support.

Some information also:
(german, use babel to translate.)

Das Problem tritt bei beiden HPUX 11.31 mit jedem der 3 genannten Linux Rechner als NFS Server auf. Es tritt nicht auf, wenn von der HPUX 11.23 Maschine aus kompiliert wird, und auch nicht, wenn auf den beiden HPUX 11.31 Rechnern auf einer lokalen Platte oder in einem über NFS gemounteten Verzeichnis, das auf der HPUX 11.23 Maschine liegt, kompiliert wird. Nur die Kombination Client: HPUX 11.31 und Server: RedHat 9 macht Probleme.

Solution:

Possible workaround is to mount the NFS filesystem in Version 2 an the 11.31 client:

$mount -F nfs -o vers=2,rsize=4096,wsize=4096 nfs-server:/share /local

Problem solved by HP Support.

Hi David,

Please refer to the workaround in this thread: http://forums1.itrc.hp.com/service/forums/questionanswer.do?threadId=1132098.

HP Support should not be telling you, or anyone, to use NFS Version 2 unless there is a very specific reason not to use Version 3 or 4. The problem you identified was related to a defect in the 11i v3 NFS client code and we've coded a fix for the problem. It will be included in the initial 11i v3 NFS patch, which is scheduled for release in September.

In the mean time, the recommended workaround is to continue using NFS v3 (or v4 if you're able) but use the rsize and wsize mount options to request a read and write request size of 8K. Again this is only a temporary measure until the September patch is released with the official fix.

Regards,

Dave
