Works for me. In the following ceasar and lindi1 are nfs clients, lindi1 is a domU with 2.6.32-27 and nova is an nfs server with 2.6.26+17+lenny1: nova:~$ ssh caesar bash -c "'for i in \$(seq 1 10000); do touch tmp/\$i; done'" nova:~$ ssh lindi1 ls tmp | sort | uniq -d nova:~$ ssh caesar mv tmp/1 tmp/1.new nova:~$ ssh lindi1 ls tmp | sort | uniq -d
