Thank you Andrew,

Since what I am going to do is manage resources on 2 nodes, one will be the 
failover of the other but there will be services running on both nodes and 
switching nodes if needed, I cannot use STONITH of suicide methods. The nodes 
will be connected to each other by LAN and also by a parallel cable to prevent 
some of connection losses.
It seems that for some reason the Heartbeat quorum daemon fails to start and if 
I change the xml configuration manually to have-quorum="1", after a few seconds 
it returns to have-quorum="0" :).

What I found in logs regarding ccm is the below:
