nfs server: 2.4.21-pre2
nfs client: 2.5.67

Every now and then I have problems copying data to and from the nfs
mount. It can either result in aborted writes like this:

15 [11:23:59] >> mv maestro.mpeg /share/funny                        
mv: closing `/share/funny/maestro.mpeg': Input/output error
15 [11:24:24] >> cp maestro.mpeg /share/funny

(it succeeded on the 2nd go)

or reads where unzip failed to unzip a file across the nfs link. there's
nothing in dmesg on either side of the fence to indicate problems and
while there was no message in the logs today, yesterday when I was
writing to the nfs server and got some corrupt files tyhis was logged:

messages:Apr  9 11:50:19 theirongiant kernel: nfs: server bob not responding, timed out
messages:Apr  9 13:15:29 theirongiant kernel: nfs: server bob not responding, timed out

But this is a local lan and the pc was never unplugged nor do problems
come up in anything else at any other time. The eepro driver didn't
detect a disconnection either.

Hope this helps. I'll do some more digging if someone can tell me what
to dig with and how. This is all I can think of atm.

Quite a few people (myself included) are seeing this.

In my case, I have a 2.8Ghz P4 as the client, hammering
a poor defenceless 1Ghz VIA C3.

This is probably worth creating a bugzilla entry for.

This is the case here also: a p3 700 hammering a k6 300.

Would this be something I'd do or someone else?

It may be worth noting that I'm not seeing any problems between an AMD XP
1800+ client running 2.5.66-mm3 and an AMD K6-2 300 server running SuSE's
2.4.18-4GB kernel. SuSE applies quite a lot of NFS-related patches to their
kernels, if I'm not mistaken.

I'm mounting /home, /var/spool/mail and /mp3 over NFS, so I think I should
have noticed problems if there were any ;-)

Unless you are using soft mounts (in which case problem == user error)
I suggest you try the latest (as of last night - probably late
afternoon Oz-time) bitkeeper. It contains a patch that has been posted
several times on this list against a 2.5. NFS client read corruption.

Cheers,
  Trond
