 From the drbd page 

| When DRBD is run over switches, use of redundant components and the
| bonding driver (in active-backup mode) is recommended.

Heartbeat itself is deprecated, has not been developed in some time and 
there are no plans to develop it in the future.

When you say "I don't worry and don't need fencing for DRBD because I 
have configurated manual fencing", it tells me you do not understand the 
importance of fencing. Manual fencing is not fencing, is prone to 
mistakes and was even removed entirely as an option in RHEL 6.

Beyond this, I don't know what else to tell you.
