Hi Sandro,
yes, it is able to handle it, the lockspace uuid is needed only form 
iscsi (lvm based) storage, which is not the case when upgrading from 
3.4, so we should be safe skipping the check for lockspace UUID in the 
setup if the storage is on nfs.

@David, I'm afraid the setup is not able to add host to the cluster 
created in 3.4, the workaround might be to deploy the host with the 
setup from 3.4 and then update it. Sorry for the inconvenience :-/
