Dual-primary works just fine in the 8.3 line. I've used it extensively
going back to 8.3.9 up to the current 8.3.13.

Thank you very much, I understand that support dual-primary mode is
included from version 8.4 of DRBD, I'll try with pacemaker, and commented
on the experience.
Greetings!

Hi,
How I can to use active-active mode or primary-primary mode? I

that I can to use with file system for a cluster GFS, etc.
Tell me please.

In DRBD, this is called "dual-primary" mode. You are write in that you
need a cluster-aware file system like GFS2, which I use, or OCFS2.
The most important thing you need to make dual-primary safe is to have a
fence device. This is a mechanism for forcing one of the nodes to power
off if the communications between the node breaks. This can be provided
by a cluster resource manager like Red Hat's cluster service or pacemaker.
Beyond this, the topic starts to get more complex. If you want more
advice, you will need to be a little more specific on what it is you
want to do.
