If you do not like the BDC stuff. Just set up a proxmox 2 node cluster. Virtualize your PDC. Set up your virtualized
Machine  a proxmox storage on glusterfs, make it HA.

Betreff: [Samba] Samba 3.6.9 - Redundancy (HA/BDC/DRBD)

Hi everybody,

our university uses a Samba 3.6.9 server as PDC for a windows domain on a single physical server (external LDAP on another server is used).
To get some redundancy up running a second physical machine was bought, which is exactly the same as the one running.

Now I´m searching for the best way to get the job done.
The first thought was to build a HA-Cluster with Corosync/Pacemaker etc. 
and mirror the data partitions via drbd.
So I would have two identical PDCs in an active/passive setup.

The question is, is there a better way to do this without scrambling my whole configuration?
If I configure a BDC (as far as I understood the BDC concept), the BDC is a read-only copy of the PDC. But I would have to sync the userdata (home dirs, profiles etc) by myself (drbd for example). So users could authenticate and login to the domain, but no changes could be made, right?

So how do you deal with the high availablity of your DCs?

Florian Götz

Mit freundlichen Grüßen
