Root.sh diskgroup already mounted in another lock name space

Question

I have successfully installed oracle grid infrastructure 11.2.0.3 and have created an oracle database on an asm instance on top of it.
I installed the database as a RAC database on a single node db-test-mi-1, postponing the addition of a second node at a later time.
Now I have a second node db-test-mi-2, that I need to add to to the database.
I have successfully performed
cluvfy stage -pre nodeadd -n db-test-mi-2 -verbose
without any errors.
When I try to extend grid infrastructure to the new node, with
./addNode.sh "CLUSTER_NEW_NODES={db-test-mi-2}" "CLUSTER_NEW_VIRTUAL_HOSTNAMES={db-test-mi-2-vip}"
it works fine, but the script /oracle/app/11.2.0/grid/root.sh, from the grid home of the second node, generates an error
ORA-15032: not all alterations performed
ORA-15017: diskgroup "DATADG" cannot be mounted
ORA-15003: diskgroup "DATADG" already mounted in another lock name space
This is because of course the ASM instance on the first node is locking the disk group.
How can I extend ASM to the second node??
Any hel greatly appreciated
