the moment the rebooted node comes up again, the two nodes are loosing

Do you happen to use the heartbeat packages of Ubuntu 8.04?
Then this might be because of a bashism in /etc/init.d/heartbeat which is
misinterpreted by the new Ubuntu default shell /bin/dash. The script
finishes immediately and does not wait for the resources to stop. As the
shutdown proceeds it removes all networking, and if this happens before the
DRBD resource is stopped by heartbeat, this causes a real split brain
situation for DRBD. Using dopd does not help with this.
Try "#!/bin/bash" instead of "#!/bin/sh" in the first line of
/etc/init.d/heartbeat and see if this helps.
See https://bugs.launchpad.net/bugs/241017 , they did not deem it necessary
to patch the LTS release :-(
The proposed solution there is to keep using /bin/sh and adapt the
misinterpreted command to /bin/dash (posix) syntax:
This is caused by line 336 of /etc/init.d/heartbeat in function StopHA,
which is misunderstood by dash:
$HA_BIN/heartbeat -k &> /dev/null
Remedy: replace with
$HA_BIN/heartbeat -k >/dev/null 2>&1
