Well, and to a certain extent this is still true. ctdb has
no provisions to migrate the PDC role when the PDC node
fails. It would mean to restart nmbd, but in a typical
clustered file server nmbd is a bit difficult to set up
anyway. Most clusters I've set up so far don't have nmbd at
So I'd recommend to split the DC roles and the HA-fileserver
cluster using ctdb. You don't need the complexity of ctdb
for your DCs anyway, PDC/BDC is highly available implicitly.
