[Samba] Registry backend changes with CTDB not noticed by other nodes?

[Paul te Bokkel]

Hi!

I'm working on a 2-node ctdb-clustered Samba. I'm almost there (hope so),
but Samba doesn't seem to notice the modified registry that is distributed
with ctdb.

On a single node the registry is working. CTDB picks up changes, including
the registry, and they are synced to the other node (verified with net conf
addshare/delshare and tdbdump on /var/ctdb/persistent/registry*).

The other node, however, only seems to use /var/lib/samba/. Testparms
doesn't return the newly created shares from the other node.

I tried several smb.conf configurations, but if I'm not mistaken, this
should be the foundation:
[global]
 clustering = yes
 config backend = registry

combined with a net conf import from another smb.conf (which works fine).

So, the question is: why doesn't smbd pick up changes in the ctdb registry?

TIA,

Paul
