NFS mount problem (YDL4.0)

[peter.g.harper at magnox.co.uk]

Jagi,

I had the same problem running 4.0 on two G5 Xserves.

The problem is that there is a bug in the nfs code for the 2.6.8 kernel
code that comes with 4.0.

That problem is cleared in 2.6.10, and presumeably the most recent 2.6.12
stable kernel.

I couldn't use those because they introduced a bug in the Fibre Channel
drivers, but
if you don't have Fibre Channel then either of those should be fine.

I hope this helps.

Subject:    NFS mount problem (YDL4.0)


(Embedded image moved to file: pic00958.jpg)
Dear all,

I'm writing about NFS mount problems.

When I accessed files in NFS mounted directory,
the NFS server machine hanged.

At that time, I got following error message at the NFS server,
"Machine check in kernel mode
Caused by (from SRR1=141000): transfer error ack signal"

Also, the following warning appear at mount time (NFS client),
"nfs warning: mount version older than kernel"

So I can not use NFS mount.

My system is as followings,
OS : Yellow Dog Linux 4.0
Machine : XServeG4 X 2
(one is the NFS server and the other is the client)

I tried some mount options like
nfsvers=3,rsize=32768,wsize=32768
But the problems does not change.

Could you give me some advice for it?
Any information from you will begreatly appreciated!
Thanks in advance.

Toru YAGI
