[Linux-HA] Failover not happening.

[nasar sherieff]

I have two node cluster as active/passive setup.

two nodes are connected through Lan. There is a serial
connection between these two nodes.

OS: Fedora core 7
s/w: heartbeat-2.0.8-1.fc7, drbd-8.0.6-3(RPMS)
Stonith not configured.
Cluster nodes: master and slave1


Problem:
When I disconnect network cable of master node,
failover is not happening.  heartbeat still running
with the resources up. drbd show primary/unknown. 
slave1 node shows secodary/unknown.

Failover happening only when master node properly
shutting down or heartbeat service stopped.


Please let me know how to solve this failover issues
when network not available, but machine is up.
