nfs soft mount, but operations still hang

[contremaitre]

Hi,

I mounted a nfs server with :
-o soft,intr,nolock,proto=udp,timeo=2,retrans=1
(tried both tcp and udp)

and then :
dd if=/dev/zero of=/mnt/mynfs/test.dd

Then I unplug my network cable, and the dd command never terminates.

Why ?

Thanks.
