9.5.3 TCP Port 7788

If your system is unable to connect to the peer, this also may be a problem of a local firewall. By
default, DRBD uses the TCP port 7788 to access the other node. Make sure that this port is
accessible on both nodes.

9.5.4 The --do-what-i-say Option

The --do-what-i-say option has been renamed to --overwrite-data-of-peer in the recent versions of
DRBD.
