Now I am curious to here if this is working for now. In the past ctdb only
worked for me only for file serving.
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
all.
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.

I asked a question like this ages ago:
If you had a shared filesystem between the PDC and BDC(s) then surely
you wouldn't need to migrate your BDC to a PDC automatically, you could
do it at your leisure. The only thing is the WINS server, which you
could either provide on a very reliable box or one with conventional
failover (no CTDB) as you won't be serving files or logons from this
machine; alternatively use smb4wins.
For your logon scripts and profiles in your LDAP you'd just point to a
virtual IP/hostname of the PDC/BDC cluster.
Volker, would this work?
Cheers
Alex
