[Pacemaker] YaST and SuSE HA add-on - DRBD configuration

Hi,

We've got the SuSE Linux Enterprise 11 HA add-on, which comes with 
OpenAIS, Pacemaker and DRBD, as well as YaST modules for configuring these.

We want to run two DRBD pairs:

  - One with ext3 in a standard master/slave configuration
  - One with ocfs2 in an active/active configuration

I have two questions:

  1. I understand I need to set net { allow-two-primaries; } in 
drbd.conf - is that correct? YaST doesn't have an option for this, and 
it overwrites the change if I put it in the file manually :-(

  2. Does each DRBD device need a unique port? The default for 
/dev/drbd1 is 7789, and I've chosen 7788 for /dev/drbd2. Is this the 
correct thing to do?

Thanks
Martin
