I setup primary/secondary drbd with heartbeat v2.
With hb_gui, the setup goes like this:
Create native resource:
Resource ID: r_drbddisk0
Parameter: Name: disk0, Value: r0
Belong to Group: g_drbd0
That's all it needs. Adjust the parameter to your setup.
I'm still hesitate on primary/primary drbd setup. Isn't it dangerous? I
mean in the context of split-brain and data integrity?
