Hi,
I'm using RH Linux 2.4.20 on both machines. When I first mount one of = the
machines with a 4k read/write blocksize, the READ requests are 4K bytes. However, when I umount and then mount again with read/write blocksize of = 8K,
the READ requests are still 4K bytes.

Any ideas on how I can properly change the blocksizes?

Thanks,
Amir.

I just ran a quick experiment on with my 2.4.20 kernel and everything seem to work as expected... How are you verifying the blocks sizes?

Steve,
I turn on nfsd debugging using '/sbin/sysctl -w = sunrpc.nfsd_debug=3D65535'.
There I see that the READ requests come in 4k blocks. Other than that = the
operation works fine (since both the client and the server agree on this 4k).

Amir.
