Sorry, I'm totally new to Samba HA.

My file servers join AD, but are not the DC itself. Does it mean that 
CTDB is an option or not?

A common FQDN would mean I simply add two A records for e.g. 
smb.samdom.example.com, resolving to each IP of the file servers? Can it 
be as simple as that?

Thanks for your help,
