Hi All
I've been running some tests using the linux NFS3 client using the
in-kernel NFS server and the unfs3 project.
I see that the client mounts the in-kernel server with default
[rw]size values of 32k and the unfs3 server using [rw]size values
of 512k. Where is this difference coming from, because I do not
specify these different [rw]size value on the command line for mount.
Through wireshark, I see that an FSINFO request is sent
by the client in order to get the wtpref and rtpref values and that is
what determines the wsize and rsize values at the client.
The next strange behaviour is that, with unfs3 as the server, I try
to mount using wsize set to 65536 with the command:
$ mount 192.168.1.201:/server/ -o wsize=65536 /test/mount
but the /proc/mounts entry still reports a 512k wsize value.
$ cat /proc/mounts
192.168.1.201:/server/ /test/mount nfs
rw,vers=3,rsize=524288,wsize=524288,hard,intr,proto=tcp,timeo=600,retrans=2,sec=sys,addr=192.168.1.201
0 0
and wireshark also shows client sending 512k requests.
mount.fs version is: mount.nfs (linux nfs-utils 1.1.4)
Is there any way to force the client to use a 64k wsize value?
Thanks

The client kernel is Debian's 2.6.18-5-amd64 and the server kernel
is Fedora's 2.6.18-92.1.6.el5.
Thanks
