It is poorly organized, and coverage certainly isn't uniform.  There are 
hundreds and hundreds of configurations that people use, and although we 
use DRBD a lot, it isn't really part of our project.

We have someone who has volunteered to help reorganize things and fill 
in gaps, but he's been busy of late.  More help would always be 
appreciated ;-).

There is a guide to installing and configuring DRBD 0.7

I wrote a  pre-drbdlinks  article on this a couple of years ago.  It is 
very thorough, and worth skimming even now.  Unfortunately, it was for 
DRBD version 0.6 and heartbeat version 1.2.x.

Sean (the author of drbdlinks) wrote a newer one - based on DRBD version 
0.7.x, and drbdlinks.  But it still was based on heartbeat 1.x.

And, there is a copy of a real-life working active-active configuration 
using heartbeat 2.0.5, and DRBD and DRBDlinks - which sets up an 
failover arrangement using NFS, Samba, DNS, DHCP, and postfix with two 
DRBD partitions.  You can find it here:

This is the configuration I run on my home production HA system.
