First off, you might try upgrading to DRBD 0.7.5 -- a few 2.4 related
bugs have been resolved:
* Fix a bug that could case read requests to return wrong data
on a node in Primary/SyncTaget state. (A very unlikely race,
it is not known that this ever triggered; It was found by an
ASSERTION in the code)
* Better compatibility with early 2.4.x kernels (BH_Launder,
min()/max())
* Touch /var/lock/subsys/drbd, needed for RedHat based distros.

Can you attach your Heartbeat & DRBD configuration files? It might be
a simple configuration error. Also, what kernel version are you
running?
Also, I found this guide quite useful:
