Like you said.

drbd1: conn( Unconnected -> WFConnection )
drbd1: Unable to bind source sock (-99)
drbd1: Unable to bind source sock (-99)
drbd1: Unable to bind source sock (-99)
drbd1: Unable to bind sock2 (-99)
drbd1: conn( WFConnection -> Disconnecting )
drbd1: Discarding network configuration.
drbd1: tl_clear()
drbd1: Connection closed
drbd1: conn( Disconnecting -> StandAlone )

I used drdbadm connect all and it worked.
