Tom,
please reproduce the problem but before doing it run the following commands
and save the output:
On the client:
nfsstat -c
netstat -m
netstat -s
On the server:
nfsstat -s
netstat -m
netstat -s
Run the rm -rf /foo
Rerun the above commands on both the client and server and of course
save the output again :-)
RTFM-ing for nfsstat I am disappointed that nfsstat does not have -z
option for zeroing out the counters. Time to look at the source :-)
