When / is exported a v4root, there doesn't need to be a uuid=3D. It is the same uuid as for /home. When I experiment I don't get a uuid=3D for /. I don't know that this would cause a problem, but maybe it does. Two extra pieces of debugging info that might be useful: 1/ Get a network trace for port 2049 traffic between client and server with tcpdump. Be sure to use "-s 0" and provide the binary packet capture - compress it and attach it to the email. 2/ Before attempting the mount, and after restarting rpc.mountd on the server and running "exportfs -f", run "strace -s 1000 -o /tmp/somefile -p ...= " on the rpc.mountd process, then try the mount, then kill strace. Then provide /tmp/somefile. NeilBrown >=20 > Can someone help with this issue? >=20 > Thanks for any help/direction you may have >=20 >=20
