[Linux-cluster] Heuristics without quorum disk

[Peter]

Hi!

I try to involve another failure detection method than heartbeat for  
failover. For example "nc -z -w3 <IP> <Port>" as a check wether the  
service behind the port is available.

The only thing i found is "heuristic program" from QDisk/quorumd. As i  
do not have a qourum disk, i am a little bit confused how to implement  
such a detection.

Can you please help me?

Thanks,

Peter
