As the primary goes down and come back on-line heartbeat is not restarted and doesn't activate LVM. This is normal in order to allow you to diagnose the problem and correct it before re activating it as a valid/reliable node. Normally if you start heartbeat it would then notice it became secondary which is normal and then drbd would synchronize. Then and only then if turn off or shutdown the secondary node will your primary reclaim its original status.
