What's the value of /proc/fs/nfsd/max_block_size? I'm not sure how it
is set, but it does not default to the max.

Hi,
I failed to mount a nfs share with a bigger rsize/wsize (in my case,
512K). The biggest rsize/wsize I can get is only 256KB on my Ubuntu
9.10 server box. Can anyone give me some suggestions?
root@d03:~# exportfs -v

root@d04:~# mount -t nfs -o wsize=524288,rsize=524288 d03:/tmp /mnt/nfs
root@d04:~# nfsstat -m

root@d03:~# uname -a
Linux d03 2.6.31-14-server #48-Ubuntu SMP Fri Oct 16 15:07:34 UTC 2009

root@d03:~# dpkg -l | grep nfs
ii nfs-common 1:1.2.0-2ubuntu8
NFS support files common to client and serve
ii nfs-kernel-server 1:1.2.0-2ubuntu8
support for NFS kernel server
According to NFS-HOWTO, I have checked the kernel const
NFSSVC_MAXBLKSIZE. It is 1M on 2.6.31.
Any comments will be appreciated!
Regards,
Rui
