As Ralph has indicated separately, you will need CTDB for filesystem
data consistency across nodes.  Samba uses CTDB as a distributed store
for metadata that is needed in addition to what is stored in the

Can you please describe why your setup requires a configuration not
(easily) supported by CTDB?

Even if it isn't possible to make CTDB do what you currently need, it
