"svc: unknown version (3)" when CONFIG_NFSD_V4=y

"svc: unknown version (3)" when CONFIG_NFSD_V4=y

[Fengguang Wu]

Hi Neil,

NFS mounting succeeded, but the kernel gives a warning.
I'm running 2.6.20-rc2-mm1.

# mount -o vers=3 localhost:/suse /mnt
[  689.651606] svc: unknown version (3)
# mount | grep suse
localhost:/suse on /mnt type nfs (rw,nfsvers=3,addr=127.0.0.1)

Any clues about it?

Short .config:

Are you perhaps running the userland NFS server instead of knfsd? The
former will only support NFSv2.

I'm running kernel nfs servers:

My system is Debian etch. And I just found that CONFIG_NFSD_V4 is irrelevant,
the message remains even if it is disabled. I'll check more kernel versions.

Thanks,
Wu

Weird.

Please try this patch.  It should provide more useful information.

root ~# mount localhost:/suse /mnt
[  132.678204] svc: unknown version (3 for prog 100227, nfsd)

I've confirmed that 2.6.20-rc2-mm1, 2.6.20-rc3-mm1, 2.6.19-rc6-mm1 all
have this warning, while 2.6.17-2-amd64 is good.

I get the same log messages here with 2.6.19.  I also noticed the following
messages when starting rpc.nfsd:

nfsd[1287]: nfssvc: writting fds to kernel failed: errno 0 (Success) 
nfsd[1287]: nfssvc: writting fds to kernel failed: errno 0 (Success) 

These messages appeared with kernel 2.6.19 too.  I however don't know if
this could be related to the other messages.
I use nfs-utils 1.0.10 on Debian Etch.

Thanks.  That helps a lot.

This patch should help too.  Please let me know.

Are you really really double-plus sure that you are running a kernel
with the patch applied?
Because at the very least it should have changed the message to

Oh, sorry. I recompiled & installed kernel and it output this new message:

[  133.129919] svc: unknown version (3 for prog 100227, nfsacl)

Ok, thanks.  I must have missed something else wrong in the code......

Probably this 'break' in the wrong place...

Could you try this patch instead please - or just move the 'break' to
where it should be.
