Hmmm, not sure. On the other cluster I did not have Samba running
before this. On this one I might have.

Anyway, changing the smb.conf to this:

clustering = yes
include = registry
config backend = registry

has made things work the way I think they should. That is, adding the
'include = registry' seems to have done it. When I was in gdb I
noticed that lp_clustering returned false all three times it was
called on one node when running net conf list, but returned true on
the last call on the first node.
