I am not entirely sure how Samba works in regards to domain controllers, my network has "real" MS Windows 2008 domain controllers and I am only using my CTDB cluster as a member server. I would suggest that any other tasks related to SMB/PDC is wise to offload to another machine, be it a real MS Windows or Samba PDC.

Emne: Scaling of ctdb & DNS round robin and scaling of pdc
I hope this is the right place to ask - I have two questions:
1. In the ctdb wiki http://wiki.samba.org/index.php/CTDB_Setup it is recommended to use dns round robin for loadbalancing.
I'm quite new to this - how does samba handle a "session". We need massive I/O for our setup and considering ctdb to avoid our smb bottleneck. When is the client getting a "different" IP- Address?
Everytime a file is read or stored - our every morning when you log into your workstation. If this is the case then loadbalancing would be quite random. The scaling figures in one of the PDFs are impressive - are these "artifical" benchmark tests or real life scaling?
2. Can the PDC be a bottleneck. Can I avoid this with samba 4 and integrated PDC? I would like to here your opinion
Thank you for your time.
